Rolls up relatively easy and rolls out and inflates relatively easy. As it says it's name is Basecamp and that is exactly it's best use. This is not a take on backpacking mat. But for car camping Etc it is at the peak of inflatable mats for comfort and durability.

Very comfy. Seems sturdy. Cannot speak to longevity as I just got it. I used it in my car. I would not recommend it if you have animals because I am unsure of how it will hold up. It is easy to inflate and keeps you nice and toasty on a cold night.

Basecamp XLUpdate... I have had this for a year now, and I've used it on three camping trips and twice as a take-along "guest bed" when visiting relatives. I still love it, and it's holding up well...As a "car camping" tent glamper, I have gone through three air mattresses that eventually sprung leaks. I should have gone straight to the Therm-a-rest n the first place. Also, since even the "regular" size is so big it is only for car camping, I suggest you go ahead and get the X-Large size. Its 30" width is comfortable for wiggly sleepers. I bring along a twin size mattress cover and sheet sheet, make up the mattress as a "bed," and put the mattress on top of my Ozark Trail zipper cot. However, I have used the mattress without the cot, and that is comfortable also. The only drawback is that the mattress should be stored in an inflated state. I keep mine behind an upright dresser. Also fits under a bed.

I had one of the very first self-inflating Thermarest pads back in the 70’s, and this new one is no exception to their outstanding quality and design. My original never leaked air or deflated unexpectedly or had structural issues the whole time I backpacked with it. I’m expecting the same great quality with this new purchase, but for car camping (we are much older now!). I was willing to spend the extra $$ on Thermarest brand because I know I can count on their quality. I love the simple improvements to the valve, the great color, and the feel of the outside fabric is just as nice as I remembered. We are looking forward to more great adventures ahead in comfort with these air mattresses (we ordered two the exact same).

Pic from left to right: Standard Thermarest - Thermarest XL Basecamp - Invoker 3†modelLongtime Thermarest owner for hard camping. Now that I “glamp†more than camp, I wanted “toppers†for the RV bed cushions in my Class B Xplorer motor home. The idea was to have an adjustable firmness topper that would store easily. I intend to store them deflated under the existing cushions. I have a full 77†length in the rear of my wide body Class B. Set up as twin beds in rear, right and left, 30†W each bed with 24†aisle between. Just my setup. I also like the idea of having my old standard Thermarest in case someone wants to sleep on the floor. The Thermarest XL fit the space perfectly. My old “standard†a bit too small. This comparison is between the Thermarest XL Basecamp and the Invoker 3†model. Both are longer and a bit wider than my “standard†Thermarest I have owned for years. I bought both the Thermarest XL & a 3†Invoker for this comparison & review.Pros & Cons: The INVOKER is 1†thicker and has a softer surface. It is more comfortable and less likely my hip bone will touch bottom side laying, if I let air out to make softer. Not really an issue in my use since they will be over other very firm cushions. The 3†Invoker is a little less than 28†wide, 2†shorter than the Thermarest XL, but love the comfort of the extra inch thick over the Thermarest. But the Thermorest XL is wider so fits better in my space. The Invoker softer surface will likely hold a fitted camp sheet a little better than the slipperier Thermarest. Naturally the thicker Invoker does not roll up as small in diameter as the thinner Thermarest. But the Thermarest XL is longer. My Thermo standard size is perfect for camping and on a pack since it’s smaller.Both inflate on their own easily in 5-10 minutes. Both have good 2 way air valves. Both you can blow inflate if you wish to make them firmer. IMHO Thermarest valve is better positioned off the surface so not to be in the way of rolling up. The Invoker valve is perfectly ok positioned on the surface but deep in the corner. However the Thermarest valve is better engineered, positioned & seems more durable. The the only reason I’m not going 5 stars is it’s just not quite thick enough w/o blowing it up a little, and that makes it too firm for me. (I’m such a whiner). I wish there was 4 1/2 star pick.Overall you won’t be disappointed with the Thermarest XL. I intended to pick the best and return the other, but I’m keeping both!

Tried all kinds of sleeping mattresses for tent and SUV camping. This is the best I've ever experienced. Very comfortable even side sleeping. Pricey but comfortable and sleeping well is more important.

The base camp self inflating mattress was a great buy 30 years ago when we camped. It still shows no wear, holds air and rolls up easily. Now, we needed another to go under a Costco 3inch memory foam for the berth on our boat. It’s perfect- thank you to a quality company that’s been around a long time!

I bought this for my daughter for Christmas. She is so happy with it. There was a slight billing issue but it was sorted out immediately. Super happy with this company and would 100% buy something from them again.

Tout d'abord je voudrais dire que c'est un matelas de TRES bonne qualité, épais, auto-gonflant et résistant. Agréable au contact avec la peau, silencieux la nuit quand on se tourne en dormant, ne glisse pas quand on y dort dessus avec son duvet. Bien isolant R value à 5,8 super aussi. Tout ça c'est génial! Le seul problème c'est son poids ! (1 150gr) ! Therm-a -rest faites un effort sortez le même produit avec les mêmes qualités mais surtout avec 40 cm DE MOINS pour les randonneurs de longue durée qui marchent SOUS LE SOLEIL des Pyrénées. Un matelas arrivant sous le genou serait suffisant long.

Apparently this has an R-rating of 6. If it does, then I am Elvis Presley. I recently took my son camping in the Derbyshire peaks in November. He had this mat, which was in a tent which was on a ground sheet. He was in thermal base layer, some joggers and a fleece, and inside a 4 season bag. It was a mild night for November, and only got down to 6°C. Well inside the the range for this type of mat.He said he could feel the cold through the mat and was shivering for much of the night. I was on an Exped Downmat with a 8 R-rating. So we swapped for the second night. He was right, this mat does very little to protect you from the cold ground. I can confirm that this mat is NOT suitable for mild British winters. It was fine during the summer, but is hopeless for all year around like Therm-a-rest claim. Very disappointed considering the cost. Getting him an Exped mat.
