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 25 lb (11.4 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.

For more information regarding the specifics of this tent, please see my initial report.

Field Conditions
During the 4 months of testing, I have taken the Tarptent Rainbow all over the Adirondack and Catskill regions of New York as well as Northern Pennsylvania.  I have seen both cool rainy spring weather as the hot and humid weather this region had most of the summer.  Precipitation is very common in this region and I was able to test the Rainbow in plenty of rain.  Average elevation for the areas surrounding my house is 500 - 2500 ft (150 - 750 m). Average temperatures during the testing time frame was 0 to 95 F (-17 to 35 C).

Final Report
Overview
Since my field report, I have taken the Rainbow out for close to 10 more nights in the field.  These nights have centered around the central region of New York state.  Temperatures during this testing time frame have been from 65 - 95 F (18 - 35 C).  There have been about an equal number of very hot humid nights and wet rainy nights.

Since my field report, and with a very hot summer, I have become all the more happy with the performance of the Tarptent Rainbow.  I've always slept very hot and as a result, sleeping in high humidity was somewhat problematic for me.  With the Rainbow and it's vast quantities of ventilation, I have actually remained quite comfortable during the nights as long as there was at least some breeze.  My views of the performance of this shelter have not changed much since the field report and I still find this to be a superb shelter.

Results
In my initial report, I outlined some specific characteristics which were important for me in a primary backpacking shelter.  I will attempt to evaluate these criteria after four full months of testing.

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.
I feel that the Tarptent Rainbow fulfills these expectations.  While I have never had a shelter breathe so well, I was a little surprised with the amount of breeze that can be felt inside the shelter.  I was initially very skeptical about how this would keep the rain out, but to my delight, it worked perfectly.  What's more, the breeze through the tent keeps the interior temperature much more bearable than less ventilated options.  I have now become quite used to feeling a breeze at night and actually enjoy knowing that I'm not going to wake up in a sauna every morning.  For me, this has been the highlight of using this shelter.

Due to the large amounts of ventilation, I'm not sure how well this shelter would perform if one was trying to keep the wind out such as during colder weather.  With the bathtub floor fastened in its raised position and the beak staked all the way down, I find I can minimize the breeze but not eliminate it completely.  For the weather I usually backpack in, and the fact that I'm a very warm sleeper, this shelter is ideal.

I also found that while the Rainbow breathes very well, in bright sun, it can still become quite warm.  I'm not usually one to use my shelter during the day, so this isn't a concern for me.  Also, I've never used a shelter that didn't warm up with direct sunlight.  

A shelter should be easy to setup, especially in adverse conditions when you need it most.
I've been known to go a bit overboard with preparation, but I cannot stress enough the need to set up this shelter a few times before taking it in the field.  My first few attempts at assembly were slow and the resulting pitch was not very tight.  I found this shelter much easier to setup using the included stakes as I could move the stakes to the optimal location for the ideal pitch.  However, after setting up the Rainbow a few times, I found that setup was very quick (quicker for me using the stakes than in free standing mode) and I could do it successfully in wind or light rain.  Due to the low weight of this shelter, I found that inserting the ridge pole into the body could become difficult in strong winds.  After four months, I can perform this quite quickly and if it's raining, I find that minimal water enters the shelter during the process.  Overall, I feel that the Tarptent Rainbow is quite easy to setup after some practice and that the included instructions were very good.  

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.
The atmosphere in this shelter is wonderful.  The lightweight silnylon lets in enough light to read by during the day yet blocks enough that it would be possible for me to sleep well into the morning if that were my style.  I also find this shelter huge for one person.  Numerous times, my wife would join me for reading before bed or playing cards.  We both fit quite comfortably for these activities and never felt overly cramped.  In my experience, I believe the Rainbow could easily sleep two people in an emergency.

As I've mentioned before, condensation was only a problem if the night was very still.  Not much can be done about this in any shelter as air simply won't move without a breeze.  I was very happy that I could raise the beak and lower the bathtub floor even during light rain without myself or my gear getting wet. The only time when I really had to fully deploy the beak and raise the floor was during a large thunderstorm with plenty of rain.

The bug netting has performed great and I have had no problems with bugs entering the Rainbow.  It is fine enough that even gnats cannot penetrate it.  All crawling creatures entered through the door when I was either entering or exiting the shelter.

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.
The shelter packs easily into the supplied silnylon bag, even when wet.  For me, the packed size of this shelter has not been a problem.  I find that I can either attach it vertically to the back of my pack, or slide it inside of my pack down one side.  The supplied stake bag is slightly on the small side especially when trying to put damp stakes in it.  They somehow seem to stick to the back making the whole process a bit difficult.  Overall, I have found little to complain about regarding packing the shelter.

On the occasions when I have the Rainbow wet, it seems to dry easily when setup in the sun or in a breeze.  If I set up the shelter during a long lunch break, it was usually dry when I resumed hiking.  Either way, the Rainbow does seem to dry quickly.

Summary
After using the Tarptent Rainbow for four months, I have seen no durability issues.  I truly enjoy this shelter and can see myself using it for years to come.

Likes:
  • Keeps the rain out while still allowing for ventilation.
  • Very easy to setup and adjust.  Stakes are great.
  • Included instructions are concise and contain all necessary information.
  • The Rainbow is very spacious for one person!  I can sit up, dress and pack my gear without worrying about bumping the walls.
Dislikes:
  • The zipper pulls are very small.  Adding small pieces of cord to them helps, but they seem to tangle the cord.
  • The hook and loop fastener on the beak holds securely, but is somewhat awkward to close from inside the tent -- especially when the beak guy line is under tension.
  • The stiffener used in the back beak (over the rear vent) seems to become deformed when packing the tent.

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