Backpacking Background:

I've been camping for several decades. I joined the Adirondack Mountain Club four years ago, the Appalachian Mountain Club a year later and am active in both. I have also expanded my backpacking to include more winter trips, mountaineering and backcountry cross country skiing, and participated in the AMC's Winter Mountaineering training program with Chauvin International Climbing Guides. More recently, I have actively studied ways to backpack lighter and more efficiently. During the summer months, my style tends toward very light, but not quite ultralight. I use a hammock or tarp for warm weather, and a small four-season tent for winter trips. Most of my other gear is very changeable, as I am constantly experimenting with gear and techniques.

The Black Diamond Lighthouse Tent:

The Black Diamond Lighthouse Tent is a two person, free-standing dome style tent. The tent is a slightly smaller, and much lighter, version of Bibler’s Ahwahnee tent. The targeted markets are mountaineering applications and lightweight backpacking. The tent is of single walled construction with interior poles. The design includes an awning and an awning pole intended to permit the rear screened window and front screened door to be left partially open in inclement weather. The front door comprises one full side of the tent and has a no-see-um mesh screen panel, permitting easy access and an enormous amount of bug free ventilation. The tent body is constructed of EPIC by Nextec fabric, a highly breathable and water resistant (not waterproof) material. The tent’s tub style floor is constructed using a grey/olive drab waterproof silnylon.

The vestibule is designed specifically for use with the Black Diamond Lighthouse Tent. It is constructed of a grey/olive drab silnylon fabric, just like the various stuff sacks and the tent floor. The vestibule uses a series of hooks to attach to the tent body and a single tensioned hoop for structure with two stakes at the vestibule door for additional support.

Initial Impressions:

The tent arrived in smallish and pleasantly lightweight box with the Black Diamond logo on the exterior. Upon opening the box, I found three grey/olive drab silnylon bags inside. The bags consisted of the stuff sack containing the tent body, another containing the DC Featherlite aluminum tent poles and the last containing the tent vestibule. There was a small hang tag attached to the pull cord of the stuff sack containing the tent body. This actually turned out to be a small booklet which provides information on the Black Diamond lightweight shelter product line in multiple languages (English, French, German and Japanese).

The Tent Body: Naturally, my curiosity was initially drawn to the EPIC by Nextec fabric of the tent body, never having seen the material before. Reading the literature provided at the Nextec website had led me to expect something different from what I had actually received. The website never discusses the 'hand' (or feel) of the EPIC by Nextec fabric. But the description of the production process (a waterproofing substance forced into the fibers of the fabric) led me to expect a fabric which resembled silnylon to some extent, which has a silicon waterproof coating. This expectation proved to be wildly in error. The first thing I noticed was how pleasantly soft and pliable the hand of the ripstop fabric was. It is easy to see how this fabric could be used to make lightweight, water resistant clothing. The bottom of the tent is made from the same 30d grey/olive drab silnylon fabric as the three stuff sacks. Typical of silnylon, the hand of the tent bottom is very light and slippery. Closer examination indicated that none of the seams were taped or sealed. The primary impression is one of lightness and delicacy.

The Tent Poles: The three DAC Featherlite poles are packed into their own silnylon bag. Curiously, this bag arrives fastened to the tent body’s stuff sack using two sewn-in black elastic loops. There is a small pocket at the top of the sack, apparently intended for the six stakes. The poles are packed with a clear plastic zip lock bag containing an owner's manual for the tent, six aluminum 6 in (15 cm) y-type tent stakes and materials for seam sealing the tent, consisting of a tube  of McNetts silicon seam sealer and a plastic syringe. This was my first time seeing DAC Featherlite poles, so I gave them close examination. They appear to be made of very thin walled aluminum tubing. The first thing that I noticed was the lack of tube ferrules. Instead, each connection is comprised of a full diameter tube section, slightly flared, which accepts the tapered end of the neighboring tube section, thus eliminating the need for the heavier ferrule. Examination of the tapered tube end reveals that there is a thin metal reinforcing insert. Each individual tube assembly is held together with a single thin piece of elastic shock cord.

The Vestibule: The longest stuff sack contains the vestibule assembly. This consists of two primary parts, a 30d silnylon vestibule body, the same grey/olive drab color as the tent floor and stuff sacks, and a single sectioned pole. Also provided are two more aluminum stakes, for anchoring the door area of the vestibule, and another tube of silicon sealer with an applicator syringe.

Tent Features:

Exterior:

There are four guy points. The guy points are located 24 in (61 cm) up from each corner of the tent body, right on the corner seam and in line with the tent poles. The guy points are made of black 1/2 in (13 mm) webbing with a wide reflective stripe right down the center. The webbing is anchored to the tent body using a doubled triangular patch of what appears to be the same material as the tent body. The guy point is assembled using an x-patterned stitch and then sewn right into the corner seams.

Corner anchor points: There are four primary anchor points, made of a 4 in (10 cm) loop of black 3/4 in (19 mm) webbing. The anchors are located right at the four corners of the tent body, typical of most tents. The tent body is heavily reinforced at the corners, as this is also where the ends of the main tent poles sit. Reinforcing is accomplished using black, rubber-backed heavy duty nylon. The rubberized face is set against the tent body, so it is only visible if one takes the time to peel back the bit of excess material at the edge of the patch.

There are two secondary anchor points located at the center of the front and back panels. These are small nylon webbing loops, sewn right into the seam which joins the silnylon bottom and tent body. As the Lighthouse uses a tub style bottom, the seam (and the loops) end up being 3 in (7.6 cm) above the bottom of the tent. As the tent stakes are 6 in (15 cm) long, it seems a small guy line should be tied to these to make them more useful. This can be done very easily, perhaps even using pieces of the guy lines provided with the tent. 30 ft (9 m) of black guy line is provided.

Interior Features:

There are two small interior pockets, sized 11 in X 4 in (28 cm X 10 cm). These are located in the center of the two side panels and are sewn into the floor/wall seam. The pockets are made from no-see-um screen material and edged with yellow nylon tape.

There are four nylon fabric loops located in the tent ceiling. The loops are positioned above my head when sitting in the tent and it appears that they are well located to support a gear loft. They form a rectangle that is 16 in X 25 in (40 cm X 64 cm) with approximately 4 in (10 cm) of 'headroom' at the tent's peak. I have never had the opportunity to use a suspended stove setup, but it seems that these loops are well located to do this. They are off center enough to leave plenty of sitting room while cooking, but not so far off center that the store would be too close to the side wall. As they are sewn into the corner seams, and therefore the tent support poles, any load placed on them is transferred to the tent structure. Note: There is a large warning tag sewn into the rear of the tub/tent body seam. This tag warns (in English and French) that the tent is not fireproof and under no circumstances should one bring a flame source of any kind into the tent.

Here is one of those little details that sets a product apart and tells me that the people over at Black Diamond are awake and really working at improving their products: Interior door/screen toggles. Every tent I have ever used has these little 'toggle-and-loop' arrangements for securing the loose material of an open tent door or screen. They work well enough and I was always glad to have a way to keep things tidy and organized (at least these things helped make it look that way!). The only real shortcoming of the 'toggle-and-loop' is that it is a fixed size. One had to hope that the manufacturer got the size right, which was not always the case. Too big and the secured panel would flop around and occasionally come undone. Too small and one could ruin an otherwise perfect day trying to get them to close. With one really clever modification, Black Diamond has changed everything. All they did was replace the toggle (normally a small, solid plastic cylinder which is tapered a bit at the ends) with a spring-loaded toggle of the type often found on a typical stuff sack, allowing the tension on the secured toggle and loop to be adjusted! In use, this is no different from a more ordinary toggle (just slip the toggle through the provided loop), EXCEPT that by pulling on the bit of nylon that secures the toggle, I can now tighten it on the secured panel. Once this is done, it leaves a very tidy secured panel that is highly unlikely to come apart until I want it to. Really and truly nice.

If the guy (or gal) who thought this up reads this review: I hope you received a raise or a bonus for this little winner. If you didn't, go ask for it now, you deserve it. Tell them I said so.

Setting Up:

My initial set up was done in a spare bedroom so I could leave the tent up long enough to apply the seam sealer and allow it to cure properly. As this was my first experience with a single walled tent, as well as a tent that uses interior poles, I departed this one time from the normal practice of my fellow males, and read the set-up instructions before trying to set the tent up!. As the process is quite a bit different from more common tents which use exterior poles under a separate fly, this proved to be a good idea.

First, I assembled all three poles. Next I spread the tent body on the floor. After making sure the tent door was open, I inserted the awning pole. This is the shortest of the three poles and has a slight peaked shape to the center section. It turns out that this pole slides through two metal (brass?) grommets located under the front and rear awning panels. The ends of this pole have aluminum inserts designed to fit into the two receiving grommets located at the center of the awning panels on small bits of black nylon webbing. Once this was done, I sat in the tent. Taking one of the main poles, I reached back to my right rear and located the right rear reinforced corner of the tent. At the base of the corner patch is a small metal snap which is supposed to accept and hold the end of the main support poles. I placed the end of the pole in the snap and then started gently bending the pole while sitting back up. Once fully upright, I continued bending the pole until I could reach the far end, which I then guided into the opposite left front corner of the tent and into the mating corner patch and snap. Once in place, I pulled the tent body over my head and the pole. I then repeated the process with the last pole, inserting the end into the left rear corner patch and snap and finishing with the right side front. Now, I started fastening the twelve hook and loop fasteners (yes, twelve) that secure the tent body directly to the poles. This takes a bit of fiddling, as the tent body develops considerable tension as this process is completed. Once done, the tent becomes quite taut around the frame. The term ‘tight as a drum’ comes right to mind. This seems a bit complex, but is much easier than it sounds. The process is much quicker than most tents I’ve used, and I expect it will go even faster as I develop more experience with the process.

The tent instructions state that the tent should be staked down immediately upon being set up. Take this seriously. The second time I tried setting up the tent (the first time outside), I stood up outside the tent to admire it and it started to fly away! There was a moderate breeze and the tent easily became airborne! Fortunately I was able to grab it and hold on without any difficulty. I then followed the instructions and promptly staked out the tent!

Assembly and installation of the vestibule is very straightforward. The single aluminum pole uses a ‘pin and grommet’ system (this is an Easton aluminum pole, not DAC Featherlite). There is a black nylon webbing strip that connects the sides of the vestibule. Once the pole is installed, this strap keeps the pole under tension while the vestibule is attached to the tent body. The grommets which accept the pins on the end of the single poles are located near the point where the webbing meets the silnylon sides of the vestibule. I placed one end of the pole into one grommet, and then gradually bend the pole until I can insert the opposite pin in the remaining grommet. This takes a fair amount of effort. Then I swing the pole into the top of the vestibule body, lining it up with the hook and loop straps. The hook and loop fasteners are then secured around the pole, securing it in position. The vestibule is now ready to install. One edge of the vestibule body has a series of hooks which mate with a matching series of webbing loops under the front awning of the tent body. The instructions recommend fastening the vestibule from the inside, stating that it is easier to see the hooks and webbing loops. This may be true, but I had no problem at all attaching the vestibule from the outside. Once this is done, it is a simple matter to pull the vestibule out tight and anchor the door panel area with the two supplied 6 in (15 cm) aluminum ‘Y’ stakes. Note: The website data tables and the tent package literature make reference to another variation on the vestibule attachment system, using clips instead of hooks. The instruction manual actually gives complete instructions on using the clip system in addition to the hook system. I do not know if other Lighthouse tents will be marketed with this alternate fastening system.

The vestibule has a small vent built into the door top. A wire stiffener holds the vent brim open. The door zipper is two sided, so the top section can be opened slightly, under the protection of the vent brim, while the most of door is zipped closed. There is a single toggle and loop to secure the door when open, but it is the traditional type, not the innovative sliding toggle used in the tent itself.

Disassembly of the tent and vestibule is essentially the reverse of assembly. While taking down the tent, I noticed another great little detail. The hook and loop fasteners used to hold the tent poles in place have a little bit of nylon webbing sewn on them. A little tug on this tab causes the fastener to come right apart. This really speeds up the breakdown process and eliminates what might otherwise be a bit of a nuisance. I note that this feature was not used on the vestibule, however.

Summary:

Things I like:
1 - Roomy design.
2 – Very light weight.
3 – That wide open panoramic door.

Things I Don’t Like:
1 – Seam sealing.
2 – I wish the vestibule shared the same innovative details as the tent.


Overall, the Black Diamond Lighthouse Tent is very impressive. The tent is a spacious and roomy design at a wonderfully low weight and equally impressive pack size. The tent in particular is loaded with nicely thought out construction details. I can’t wait to get this out into the woods and mountains to try it out.

I was surprised that the tent required seam sealing. Is it possible that the EPIC by Nextec fabric does not lend itself to seam taping? I find it odd that some of the features of the Lighthouse are not used in the vestibule (specifically the hook and loop tabs, the sliding toggle and the DAC Featherlite poles), as the vestibule is an option dedicated to the Lighthouse tent. The effect is that the vestibule comes off as a bit ‘pedestrian’ while the tent shines in these many details. Otherwise, this is a really impressive tent/vestibule combination.

Test Plan:

As the Black Diamond Lighthouse Tent offers some new technology to the single wall tent world, this test will require special consideration on this point. Constructed of Nextec’s proprietary EPIC fabric, the tent is supposed to offer unexcelled breathability. Naturally, this is intended to reduce the longtime bug-a-boo of single walled tents: interior condensation. This factor has generally limited single wall tents to high alpine or very cold weather use. It is of particular interest to me that Black Diamond is offering these tents to be tested outside of the normally recommended environments. This would indicate some confidence on their part that they have a real improvement to offer. Accordingly, I will seek out conditions that put the EPIC by Nextec fabric to the test. This will include wet lake shore environments and rainy, damp weather. A great deal of the field time will be spent in the Adirondack Lake regions, the Catskill Mountains and Harriman State Park.

A visit to the Nextec and Couloir Online websites gives some good information on the theory behind the EPIC fabric, as well as information on its structure and properties. As a woven, non-laminated fabric (the treatment is imbedded in the individual fabric fibers rather than the traditional surface laminate), it is easy to see how the fabric would have improved breathability. It is also easy to wonder about the degree of water-resistance. How long will the fabric hold up to a thunderstorm before leaks start to show up? Will this improved breathability eliminate condensation?

The Black Diamond Lighthouse Tent is based on the Bibler Ahwahnee tent, but the floor dimensions have been scaled down slightly to the dimensions of the Bibler Eldorado. As a ‘big and tall’ kind of guy, I can fill up a two person tent pretty quickly. The Lighthouse is not huge, but seems to be quite roomy for my wife and myself. The tents ability to house us and our gear will be checked both with and without the vestibule. It should be positively cavernous for solo trips.

Of, course, the more typical tent issues will be considered:

-Does the vestibule offer enough room for gear storage and cooking in foul weather?
-How much more difficult does the vestibule make entering and exiting the tent.
-Do the interior poles offer some advantages in setting up, such as erecting from the inside during a rain storm?
-Is this pole system easier or more difficult than an exterior pole system at the end of a long day?
-Is the vestibule/tent joint weatherproof?
-How does the vestibule affect ventilation in warm weather? Or rainy weather?
-How does the design hold up to wind? Are the DAC Featherlite poles strong enough for exposed tent sites?
-Is the EPIC fabric so breathable that it affects the tents heat retention in cool weather?
-How durable is the silnylon floor of the tent?
-How durable is the silnylon construction of the vestibule?
-How durable is the EPIC by Nextec fabric?

Overall, can the tent be expected to last for many years of use, or will the lighter fabrics compromise longevity?

I would like to thank Black Diamond Equipment for the opportunity to test this tent and vestibule.
