DO NOT BUY - take it from someone with 20+ years of experience

This is the worst sleeping pad I have ever used! The thing does not stay inflated by morning it is flat no matter what I do and under what conditions I use it. In addition, the gray portion of the stuff / pump sack ripped off within 1.5 years of use. I purchased this pad because it got good reviews especially for side sleepers and those with back pain. It turns out the only good thing this is good for is to add additional weight to your pack....I can find better uses for that space and weight. Not sure how this thing got all the awards and good reviews but it certainty will not get one from this user.

[This review was collected as part of a promotion.] Love this pad! For the comfort it provides, I do not mind the extra space it takes. I kayak camp so the added weight is no issue at all. I sleep so well on this pad! I love that you can blow the bottom up separately to provide more cushion especially if there are tree roots. So happy with my purchase.

Great pad. Comfortable and easy to inflate. Does wonderful in Cold weather. Have used it on the Appalachian trail in January February and June. No problems.

Comfort Plus is a game-changer!

I used to think I'd never get a good night's sleep in the backcountry. The Comfort Plus Insulated Air mat has changed that! The dual-layer system lets me customize a softer sleeping surface while keeping the bottom layer fully inflated to protect from hard ground. And I love that it provides redundancy in case of puncture, though I've been using it for years and have never worried about its durability. The only drawbacks are weight and packed size, but it's still my go-to pad for most trips because sleeping well and comfortably makes everything else better, too!

Arctic Airborne Infantry Certified

I bought this sleeping mat for the first time in 2016. I was stationed in Alaska as an Airborne Infantryman in the United States Army. This sleeping pad endured for 3 years in that environment. It held up in 40+ Airborne exercises in extreme cold temperatures for weeks at a time and a deployment to Afghanistan. Sleeping on it was something I always looked forward too. It continued to serve me well leading into 2022 when I finally passed it on to a friend and bought me a new one. The new one served me well in the swamps of Louisiana and the blistering heat of Eastern North Carolina while on active duty and even now, as a civilian, it is still going strong. Treated with respect, I imagine this pad will last the average person the better part of a decade. I have never had one fail in any way, but if it does and you forgot your included patch kit, it is compartmentalized, so the opposite half will retain air. To this day, I use it for camping and I keep it deployed full-time in a spare bedroom where I still sleep on it occasionally. It is very comfortable and effective. I highly recommend this product.

[This review was collected as part of a promotion.] Most comfortable pad ever, although its the first "good" pad iv tried it definitely sets a new standard for everything i sleep on (bed or otherwise) from this day forth. If its in the budget pull the trigger, otherwise there are cheaper ones that will work just fine. Don't get too caught up in R ratings unless your goin into some nasty nasty weather then you're going to splurge on all your gear anyways.

Slick sleeping surface

First off, I love my Comfort plus. As a side sleeper it’s always difficult to find a comfortable sleeping pad. I tend to camp in cold weather and during the last cold camp it got down to 16°f. My toes were cold in my 0° sleeping bag but that was it. I’d say my biggest complaint is that it skids around on my silpoly tent floor. I wish they still made the Comfort Plus in a rectangular model. The weight difference wasn’t that dramatic and I could keep my feet off the ground. All in all, a great pad for packed size, R value and comfort.

Great Buy!!

[This review was collected as part of a promotion.] Best pack friendly mattress out their hands down. Used in 12 degree snow and in the summer. Had to replace one my dog tore up while out getting supplies.

worked well but...

Love this pad. But some warning. In a 4 season tent, at about 15 F, in a sleeping bag with a 17 F comfort rating, with this pad and a closed cell pad underneath it (total R rating over 6), wearing thermals, down socks, down jacket, down pants, wool baclava i got cold. What saved me from losing sleep were hand warmers. Put one in each sock and one in each pocket of down parka (total of 4) at about 0200. Slept nice and toasty after that. Moral - consider taking hand warmers with you when temps are going below 20 F.

Comfort Plus Insulated Mat

For a side-sleeper, this is the best mat I've found. The fact that it has two compartments means a puncture isn't a disaster, a problem that occurred to me on a mattress by a different manufacturer.
