My Story:
Well the Eclipse was upon us. While many people flocked to huge gatherings to enjoy this once in a lifetime even with hordes of others I took the opposite approach. I loaded my family up and headed to the hills. It was time to get up on a mountain top to be in the best place on earth and witness one of the greatest phenomenon’s we have the pleasure of viewing. I had the plan all worked out and luckily I also had the gear.
After the Summer Outdoor Retail show I made arrangements to test and review the Therm-A-Rest UltraLite Cot and Cot Tent. When the box arrived at my home I was overjoyed to open it and set the cot up right in my living room. It took me a second to figure out how to make everything go together but the process was simple enough and after my test run in the house I was ready to get out to the woods. It is important to note that the Tent Cot does not actually come with a cot. You would have to purchase that along with the Tent to make certain the system is complete. Now, let’s get on to business!

I first set up this system at my home under ideal conditions. My experience at home told me that I was not going to really be comfortable unless I used all of the cross poles and so I made sure to pack the cot in its entirety. This adds weight but I was willing to sacrifice that for the added comfort. I paired the cot with the THERM-A-REST NeoAir XLite MAX SV mattress and found it to be a very comfortable setup. This cot is comfortable without the pad but I brought it along as I needed to test it as well.

When out in the woods the cot assembled just as nicely as it had in my living room. I found it to be a great addition to my gear as it helped make a perfect sleeping platform in an area of not so perfect ground.

The cot tent was pretty user friendly and it only took about 2 minutes for me to have it assembled and up in the mesh version. I was unable to use the fly inside the living room. My test run at home proved what I already suspected to be true which was that this thing is tight. When laying in the tent I felt pretty cramped. On the mountain I felt that same confinement and it did create a bit of discomfort for me during the night. I am 5’ 9’’ and my toes easily touch the end of the mesh.
The night was clear and bright so I chose to leave the fly off. I wanted to see the stars and the mesh was fantastic for this. I lay in the tent nice and warm and drifted off to sleep. Injuries of the past bring with them a lasting restlessness that makes nights outside of my bed at home a bit of a rough time. This night was no different and while I did find sleep there were a few restless moments in which the confining feeling of the tent only added to my discomfort. I believe that if a person were any larger than myself they would have a very difficult time finding comfort in the regular size tent. On a positive note I was able to catch a great sunrise photo after my back decided it was time to wake up.

I was unable to get a good rain storm so I had to improvise and make a small rain storm in my yard. I am happy to report that after as sold 2 hour span the test results were a very dry interior. The tent is a solid performer in the wet and nasties and the fact that the sleeping platform is off the ground is a great way to insure a nice dry night’s sleep.

Overall I was pleased with the both of the products in regards to assembly and performance. They both work well. I would like to see a bit more room in the tent but I’m not sure that is possible with the current design. The system is a bit heavy and I believe that some weight could be cut by using a little lighter rainfly material. This is not for the UL hiker but would be fantastic for weekend trips or 2-4 day hiking trips. The whole system weighs in at about 5 LBS 4 oz. which is a bit heavy for a single person shelter. Add the THERM-A-REST NeoAir XLite MAX SV or similar pad to the mix and you are going to be over 6 LBS for a single person shelter.

What could be done better?
I would like to see the weight cut just a little bit. I think that the rainfly could be made out of a bit lighter material and still offer great protection. I would also like to note that if you are larger than 5’ 9’’ you are going to want the L/XL cot and tent. I found myself wishing for the extra room. The products all function as advertised and seem to be made well. Therm-A-Rest offers a great warranty in the event that anything was to go wrong so you can buy with confidence.

I give the cot at 4.5 rating as it was comfortable and functional. The Cot Tent was functional but a bit stuffy and on the heavy side. I give the tent a 4. This brings the system total to 4.25 Stars.
