A Brief Introduction
I grew up camping with my parents and had taken a few short backpacking trips, as well as a couple of 10-day trips before I got married. While my wife and I have enjoyed car camping and day hiking for close to 6 years, this year we have decided to make backpacking a permanent part of our lives. Our trips are generally shorter (2 - 5 days) over rocky, hilly terrain. My general pack weight for a 3 day trip is around 35 lb (16 kg) including food and water.

The Tarptent Rainbow is a new offering by Tarptent this year.  It is a 1-2 person tent which boasts the ability to be pitched free standing with the use of 2 trekking poles.  Using stakes, the tent can also be pitched without trekking poles, but it will not be free standing.  As with all shelters made by Tarptent, the Rainbow is a single walled shelter designed to promote exceptional airflow and reduce condensation while boasting a low weight.  There are two versions available -- one with a sewn in "bathtub" style floor, and one with no floor.  I received the style with the sewn in floor.

Tarptent Dimensions

Included with the Rainbow is one Easton aluminum pole, 6 Easton aluminum stakes with silnylon pouch, the shelter body and a silnylon stuff sack to hold everything.  There is also a one page instruction sheet which includes setup directions as well as directions for seam sealing.  This instruction page is also available on the manufacturer's web page.

In order to determine the measured weight for individual applications, I weighed each element separately.  The measured weight is as follows:
Tent Body:
Pole:
Stakes (each):
Stuff Sack:
Total:
23.6 oz (670 g)
5.8 oz (163 g)
0.4 oz (10.6 g)
0.6 oz (17.5 g)
32.3 oz (914 g)
It is important to note that the above calculated weight is given assuming that all 6 stakes are carried.  According to the manufacturer's web site, only two stakes are required when using the tent as free standing with trekking poles -- one for the beak and one to guy out the back side.  This would bring the total carried weight down to 30.75 oz (872 g).

Erecting the Shelter
After laying out all the components, I decided to follow the manufacturers directions for pitching the shelter in its freestanding mode.  To begin, I inserted the included pole through the pole sleeve.  The pole sleeve is made of yellow fabric and it is quite easy to find.  Once inserted, the pole ends are secured in a grommet on either end of the shelter.  From here, it's simply a matter of securing the trekking poles to either end and looping the corner pull-outs to the ends of the trekking poles.  Since I have the sewn in floor, the corners of the floor have shock cord loops which are looped over the ends of the trekking poles as well.  The manufacturer recommends that the trekking poles be adjusted to at least 50 in (125 cm) in length, but I found that slightly longer seemed to provide a more taut pitch.  After all corners are secure, the tent is completely free standing.  At this point, all that is left is to (optionally) stake out the beak and the one tie out point directly across from the door.  In nice weather, neither of these steps are really necessary.  I've only erected the shelter twice, and I would say I can do it by myself in under 5 minutes.

Initial Impressions
This tent is very well made.  Everything fits together just perfectly and I can achieve a taut pitch without a whole lot of effort.  Once set up, the tent is absolutely beautiful!  The interior is bright enough not to feel gloomy when the sun is out, but still blocks enough light that I could see myself napping quite easily in bright sun without a problem.

The Interior
The interior of the tent is nothing short of spacious for one person.  In fact, I could easily fit two 3/4 length inflatable pads side by side.  It would be a tight fit, but two persons could share this shelter if absolutely necessary.  Also, the Rainbow is quite long.  I could easily put my pack at the foot of my sleeping bag without cramping my feet.  The interior height is also quite nice.  Not only is it tall enough in the middle to sit on my knees, the arch of the pole provides very steep sides so I had no worries about brushing my head or shoulders against anything while sitting up.  Two people could definitely sit facing each other to play cards or other camp type activities without feeling cramped.

Ventilation
Tarptent goes out of the way to provide plenty of ventilation.  The rainbow is no exception in this category.  Not only is the front all mesh with an ample beak to keep the rain out, there is ventilation directly across from the door near the peak of the tent.  This vent is adjustable with hook and loop fastener and can close during a storm (in theory, to keep the elements out).  To provide even further ventilation, there is mesh all around the floor of the tent!  The sewn in floor does somewhat negate this ventilation, but the floor un-clips at all four corners and lays flat when there is no risk of rain to gain back the ventilation properties.  

Field Conditions
I try to get out in nature at least twice a month either car camping or backpacking. Most of the trips involve two nights of camping. The Tarptent Rainbow will accompany me on all such excursions and be used for my shelter during the testing time frame.

Most of my hiking and backpacking trips center around the Adirondack and Catskill regions of New York as well as numerous overnight trips along the Finger Lakes Trail which passes within 10 miles (16 km) of my home. Due to the timing of this test, it would not be unreasonable to expect a wide range of weather conditions from harsh winter to warm summer months. Precipitation is very common in this region so snow and rain are almost a certainty. Average elevation for the areas surrounding my house is 500 - 2500 ft (150 - 750 m). Average temperatures during the testing time frame 0 - 80 F (-17 - 25C).

Also, during the first couple weeks of June, my wife and I are planning a thru-hike of the Northville Placid Trail. This would be around a 14 day trip. Elevations would range from around 800 - 2500 ft (250 - 750 m) and the average temperature around this time is 45 - 75 F (7 - 24 C).

Test Plan
I plan to test the following aspects of the Tarptent Rainbow over the testing period:

A shelter must keep me and my gear safe from the elements. To me, this means keeping me dry when it’s raining and shaded when it’s sunny. It must also block the wind.
  1. Does the Rainbow prevent water from entering during a storm? What about wind blown rain?
  2. How well does the high shielded vent flap protect the vent when closed?
  3. How well does the beak keep water out of the entrance?
  4. How much water, mud and debris splash under the fly and enter the living space?
  5. How well does the Rainbow protect me from the wind? Does it shake excessively or does the wind blow past easily?
  6. Is it necessary to guy out the back wall and the front beak for the tent to shelter me from the elements?
  7. Is it necessary to stake down the corners for the tent to be stable during normal use?
  8. Is there enough room for my gear either under the beak or in the shelter?
  9. Does the tent arrive with all the seams sealed? If the user is responsible for this, are adequate directions given?

A shelter should be easy to setup, especially in adverse conditions when you need it most.
  1. How easy is the rainbow to setup? The website claims that all tarptents can be setup in 2 minutes. Can I meet or beat this number with practice?
  2. Can I set it up during a downpour without getting the inside completely wet?
  3. Does the pole slide easily into the pole sleeve even when both are wet?
  4. How easily do the corner pullouts adjust?
  5. How hard is it to adjust and secure my hiking poles?
  6. How hard is it to setup the beak and rear vent flap?
  7. Can I do all the above things with gloves on?
  8. Can I setup the Rainbow successfully with or without the trekking poles?
  9. Are there any limitations to what sorts of trekking poles work with the Rainbow?
  10. Do the supplied stakes work well in various soils?

A shelter must be comfortable to live in. It must keep out unwanted pests (bugs and such) and ventilate well enough not to feel stuffy or cause condensation.
  1. The Rainbow is made from a very lightweight silnylon. Does this material let in enough light to be cheery while waiting out a storm? Too much light to sleep at night with a full moon?
  2. Does the bug netting on the front of the tent seal well enough to keep out biting insects?
  3. There are many ventilation options. I sleep very warm and have  tremendous problems with condensation in every tent I’ve tried. Does this ventilation allow for enough airflow, even during hard rains, to keep the inside relatively moisture free?
  4. Is there enough interior space to sit up? Can my wife and I both sit facing each other in the tent to wait out storms?
  5. Do I feel cramped in this tent? Can I easily maneuver around to dress / undress without hitting the walls?
  6. Do I have any trouble with my sleeping pad sliding around inside the tent, causing me to constantly have to re-adjust myself during the night?
  7. If necessary, how hard would it be to cook under the beak? Is it even practical?

A shelter must pack well, even when wet. It must not take up too much precious pack space. It must be lightweight while not sacrificing the above necessary traits.
  1. Does the shelter pack in a shape that is easy to pack on the inside or outside of my pack?
  2. How quickly does the shelter dry when completely wet?
Finally, I will report on any other findings which merit mention during the length of the test.

Summary
After setting up the tent a couple of times and seeing the interior, I have to say that I think this is going to be one fun test!  

Likes:
  • Quite easy to setup
  • The one page instruction sheet included is very easy to read and quite descriptive.
  • Easy entrance and exit from the tent
Dislikes:
  • Really nothing to complain about, but I did notice that there was no included repair sleeve for the pole.

I would like to thank Tarptent and BackpackGearTest.org for the opportunity to participate in this test!
