Main benefits

  • Extraordinary lightweight system: 2.66 kg both tent and cot.
  • Both tent and cot are collapsible to very small packed sizes.
  • This is a tool with 3-in-1 features. Both tent and cot can be used separately.
  • The system is completely portable in a backpack.

Check on Amazon.


As mentioned above, this is an ultra lightweight set which is without a match in this industry. The system which you have here is difficult to compare with any other model described in this site. This is mainly because what you have here is completely portable, unlike any other available on the market.

Typically what you have with tent cots are relatively heavy structures which are great when used in a camp with car access, but in general, they are not portable. However, with 5 lb 14 oz (2.66 kg) this Thermarest cot tent can be carried, so it can indeed be used by hikers and mountaineers.

Because the tent and the cot are separately packed, you have a true 3-in-1 system. So you can use the tent completely separately if you are on a long tour and want to save weight.

The cot alone can be used in any environment, outdoor and at home, or as a bed in emergency situations.

Tent specifications & features

The tent comes with the top fabric which provides a complete shelter from insects, and you also have a rain fly included to protect you from elements.

The package includes a pole which gives you an unusually high dome, with the peak at 140 cm. This is rarely seen in any tent of this type. The attachment of the tent to the pole is through hooks and velcro tabs. To attach it to the cot you will use straps that are available. You will see details in the video below.

The package includes 4 stakes which you will use in the usual way to fix the tent to the ground.

The cot: Thermarest LuxuryLite UltraLite Cot

There are several types of Thermarest cots available on the market. Here I give data for one of them, the Thermarest LuxuryLite UltraLite Cot.

This is Thermarest’s BowFrame technology, their patented BowFrame design, and presently this is the lightest cot available on the market. This makes it suitable even for backpackers.

From the video below you will realize that it is incredibly packable. You can attach it to any backpack or carry it inside of it. Note, the cot can be ordered separately, check here.

In the same time, this is a very durable construction with strong polyester feet and with anodized aluminum poles. The top cover is waterproof stretch-free polyester.

The setup may look complicated (see the video below) but in fact, this is a three-minute process without any additional tools, a truly unique design. In any case, I feel it is indeed worth the efforts.

In 2017 Therm-a-Rest has launched a new version of this incredible cot, so you can see my full review here.

Here is the summary of specifications for the cot:

  • Two sizes: R, L.

    – R: 3 lbs (1.36 kg).
    – L: 3 lbs 6 oz (1.53).

Pros & cons

My summary of possible cons and pros for this Therm-a-Rest tent cot is as follows:


  • Quite short bed & tent.
  • Not so simple procedure of setting up the cot.


  • Complete protection from elements.
  • Comfortable sleeping.
  • Everything collapsible.
  • Extraordinary lightweight.

This tent cot is made quite short, hard to understand why they made it that way. So for most people the only option is to choose the L model.

But the cot has been very popular, and at Amazon it has received a huge number of reviews, presently almost one hundred. The average rate is 4.2/5.

I wish to stress that this cot has been subject to real testing in the field. There are several reports available here, so please have a look. Do not be confused with the name Cascade Designs which you see in these reports; this is the name of the company which actually owns Therm-a-Rest (or Thermarest).

Comparison with competitors

Thermarest cot tent is quite unique and there are no many models on the market to compare it. Nevertheless, in this table I give its data side by side with some other models.

For Thermarest I use data for the L/XL model, and as you see it is still considerably shorter than the other models. But see the weight and the height.

Bed size, inches (cm)
Tent Height, inches (cm) Packed size inches (cm)
Weight, lb (kg)
Therma Rest* 26 x 77 (66 x 196) 55.12 (140)
Separate parts, see above. 5 lb 14 oz (2.66)
OUTAD tent cot 78.7 x 26 (200 x 66) 45.3 (115)
19.7 x 5.9 x 5.9 (50 x 15 x 15) 5.84 (2.65)
KR oversize 32 x 90 (81 x 229) 36 (91)

36 x 34 x 7 (92 x 86 x 18) 34 (15.4)
KR Compact Collapsible 29 x 79 (74 x 201) 39 (99)
43 x 10 x 9 (109 x 25 x 23) 25 (11.3)

*This is for L model.

KR = Kamp Rite.

The most similar model in the table is the OUTAD tent cot, so please follow the link to see some more details about it.


So to conclude this Thermarest cot tent review, what you have here is a completely innovative and unique system, a 3-in-1 tool, packable and portable. I can fully recommend this tool. Note that this is not the only portable tent-cot of this type, see also this FUNS Off Ground tool.

If this tent cot concept is completely new to you, you can read here a bit about advantages of this system.

Therm-a-Rest is a renown outdoor equipment company which has been in this industry for almost half a century. This is the company which became world famous for the invention of self-inflating mattresses.

  1. A very thorough review. I like that you even included a video on how to setup a tent. I’m quite confident that someone that’s never pitched a tent before will be able to do it with ease after your informative instructions. I also like your honesty in listing not only the pros but the cons as well. Like this people will know exactly what they’re buying. Well done!

    1. Thank you George, very kind words, this means a lot to me. I really like these tools and it is great to hear that others like them as well. All the best to you.

  2. DUDE this product also is AWESOME! I have just visited yet another post in your site. These tools are completely new to me.
    Thanks again!

  3. The Thermarest Cot Tent seems like a good product to go hiking or camping. I enjoy that it can be carried in a backpack and that it is lightweight so if I were to go hiking with it it would not be to much to carry around. I love that the tent and cot can be separated. Do you have a personal favorite when it comes to tents? And do you think this tent is made for more casual use like backyard camping, or for maybe staying in the wilderness for a few days?

    1. Hi Kevin, thank you for the comment. This Thermarest model is in fact my favorite because of the reasons you mentioned. Thermarest is a famous brand, they have invented self-inflating pads, and they produce a lot of top class items. So this is indeed a reliable tool, not just for casual use.
