Background: Thru-hiked the Appalachian Trail in 1994. Moved to Pacific Northwest 1996 and enjoyed day hiking excursions in the Columbia River Gorge area, followed by some backpacking along the Pacific Crest Trail. Moved to the desert southwest in 1997 and have been actively day hiking most weekends. I generally take 2 weeklong trips to the Grand Canyon each year. Backpacking philosophy has been rapidly moving towards ultra-light gear. My current base pack weight (not including food or water) measures about 10 lbs (4.5 kg).

Field and Test Information:

Location(s) of test:

The Starlite was taken on a 7 week trip to Europe which included day hiking and backpacking in both Spain and Switzerland. The pack was in almost continuous use during this period.

Terrain:

Terrain was mountainous with a considerable amount of elevation gain/loss required. Trails consisted of dirt, rock, grass and snow. Elevations ranged from 3000 to 7000 feet (915 to 2100 meters) above sea level.

Weather Conditions:

Weather conditions were variable with highs in the 90's F (32 C) and night time temperatures below freezing. Weather was mostly sunny with occasional clouds and an occasional heavy downpour.

 

Description of Experience and Comments on Product Performance:
Being fortunate enough to have an extended break from work, I traveled to Europe to enjoy some outdoor activities in the Spanish Pyrenees and in the Swiss Alps. Since I was only able to carry a limited amount of gear, the Starlite pack served a variety of purposes in addition to its role as an ultralight backpack. The first presented itself during the initial plane flight. By removing the aluminum stays and sliding those into my checked baggage, the Starlite was used as a carry-on bag for the long flight. In this capacity, I found that it served quite well. I used the external mesh pockets for frequently used items or those that I would want to quickly remove before taking my seat. The pack is also about the same size as the airline carry-on baggage limit, and fit well into overhead bins. Once at my destination I simply slid in the aluminum stays and was ready to begin hiking.

Backpacking and Day Hiking in the Spanish Pyrenees:
The Starlite was carried on a backpacking trip in Ordessa GorgeOrdessa Gorge in the Spanish Pyrenees. As luck would have it, the first day of my hike began with light drizzle, which became an off and on heavy downpour that lasted throughout the day. For light weight backpacking trips I typically do not use a pack cover since they add weight and usually do not fit very well over the outside of my packs. Instead, I prefer to place items that I need to keep dry into a water resistant bag inside the pack (usually a kitchen trash compactor bag). This trip was no exception. The pack was loaded and the roll top closure secured in place. No other pack cover was used during the hike. With the pack being deluged with water the entire day, I expected to find it saturated upon arriving at my destination. Surprisingly, I found that a only small amount of water had entered the pack at the top, making the contents loaded just under the roll top slightly damp. The rest of the contents of the pack were completely dry. My experience is that the manufacturer's claim that the dry bag closure "keeps your gear dry and contained" is true. This is not a waterproof pack, and the manufacturer makes no claims that it is, however, it gets high marks in the weather resistant category.

The pack was loaded with somewhat more weight than I had carried in the past due to the extended nature of the trip. Though I did not have access a scale I estimate the total weight at between 25 - 30 lbs (11 - 14 kg). The pack carried fairly well on the trip, however, with this heavier weight I began to notice a problem with the load lifters on the pack.
Note: It should be mentioned that the issues described below were communicated to the manufacturer and the design of the pack has been changed to eliminate these issues. I will describe these problems anyway, since they were part of my experience with the pack provided me for this test series.

First a quick description of this portion of the pack. The shoulder straps of the pack are connected to the pack body with an acetal buckle. A piece of ¾ inch (2 cm) flat webbing runs along the top of the shoulder strap, through an acetal triglide to a point where it is stitched to the strap. Another webbing strap runs from this stitched point, through the same triglide, then up to an acetal load lifter located just below the pack's extension collar. The purpose of this design is to allow the user to adjust the angle at which the load lifter strap rises off of the should strap. This is important since load lifters function optimally when this angle is at 45 degrees. The angle is adjusted simply by sliding the triglide up or down along the webbing over the shoulder strap.

Back to the problem. The issue I began to notice as I hiked with this somewhat heavier load is that the triglide, which determines the angle of the load lifter strap, did not hold tension. In fact it would slide to the highest point it was able on the should strap making the load lifters ineffective and causing the top of the pack to hang back off my shoulders. I believe this also put a considerable amount of tension on the webbing described above that runs through the triglide, since the webbing on the right shoulder strap tore where it connects to the top of the strap.

and torn webbing.

Because the triglide kept sliding up to the highest point (where now the webbing was torn), I eventually hand tacked it down to prevent it from sliding off the end of the torn webbing so that I could continue my trip.

It should also be noted that the same type of triglide is used to attach the lower webbing of the shoulder strap to the pack body. I found that slippage also occurred at this triglide and even had the entire shoulder strap disconnect at one point as I hiked. Clearly the triglide slippage issue is one that creates significant problems for the hiker.

The other problem I found with the pack is with the webbing sleeves into which the aluminum stays are inserted. When the stays are supporting the weight of the pack's contents, the force of the load is transferred to the top and bottom of the webbing sleeves. Unfortunately the webbing used in the packs construction consists of a loose weave, and I found it was unable to withstand the forces required to carry the load day after day. The bottom of the right webbing sleeve tore, allowing the aluminum stay to protrude through the bottom. This eliminated the ability for this stay to bear any load since it just slid down to the bottom of the inner pack.

Product Update:
Since experiencing these difficulties, the manufacturer has changed the design of the Starlite to eliminate these problems. A different type of webbing has been used for the load lifters which allows the triglides to maintain tension. The stay sleeves were also updated and now use a heavier webbing with a tighter weave which should prevent damage by the aluminum stay. The manufacturer has also begun folding over and sewing the webbing which connects the lower portion of the shoulder strap to the pack body after it passes through the triglide to prevent it from sliding off. The manufacturer has sent me a new pack body which has incorporated these changes and I have not experienced these same problems with this new design. It should be mentioned, however, that I have also not had the opportunity to go on another extended 7 week excursion either.

Other than the issues described above, there was no other damage to the pack or body. The pack has otherwise held up well even after an extended period of continuous use.

 
Summary:
Brecht de RolandoThe initial design of the Starlite had several significant design flaws which presented a major inconvenience for me. These flaws quickly became apparent when carrying a heavier load - 30 lbs (14 kg), which is still below the maximum weight of 35 lbs (16 kg) recommended by the manufacturer. Six Moon Designs appears to be very willing to accept user input into the design of their pack and appears to have corrected these issues with their current version of the Starlite.

With the pack functioning as intended, I find it to be comfortable and easy to pack and carry. The pack offers many of the advantages of a backpack with full suspension in a lightweight design. The suspension does a good job of transferring the weight of the pack to the my hips and the padded shoulder straps and hip belt are quite comfortable. The external mesh pockets allow access to frequently used items and the right pocket allowed me to grab my camera or snacks without removing the pack. This pocket is a bit difficult for me to reach, though this might be due to the fact that I have long arms and have to bend awkwardly to get my hand high enough to reach into it.

The roll top closure and pack materials do a good job at repelling water and appear to be fairly durable over the long term. I did experience damage to the webbing of the original pack during what I would consider normal use. Because the pack was replaced fairly late in this test series, I can not comment as to long term durability of the redesigned Starlite.

Overall I think Six Moon Designs has a solid design in the Starlite pack and it has become my pack of choice for light weight backpacking trips.

 
Likes:
  • Light weight
  • Comfortable to carry
  • Suspension transfers the load of the pack to my hips
  • External mesh pockets allow easy access to frequently used items
  • Surprisingly weather resistant
Areas for Improvement:
  • Triglide slippage and weak stay sleeve webbing create significant problems for the backpacker. These issues appear to have been corrected with the current design of the Starlite.
  • I'd like to have a dedicated water bladder pocket which keeps the contents of the bladder close to my back
  • Mesh side pockets are a bit too loose, all items fall to the bottom of the pocket in a heap
  • The roll top closure system should have an omni-directional side release buckle
General Comment:
  • I have to be a bit of a contortionist to be able to reach into the right side mesh side pocket
