Comfortable, packable, light, and user friendly, at a good price—that was my verdict after I used this air mat on a five-day backpacking trip in Washington’s Glacier Peak Wilderness and a six-day hike in Sequoia National Park. It has a quality that’s important in an air mattress—durability: Thanks to the 30-denier ripstop polyester fabric and welded construction, I slept under the stars on pebbly gravel at Columbine Lake in Sequoia, and used it nightly in my chair kit sitting around campsites, without the Flash springing a leak.

REI Flash air mat2Although it’s a full-length, six-foot air mattress, and a plush two-and-a-half inches thick, it packs down to slightly larger than a liter bottle. The one-way valves—one to inflate, one to deflate—keep air from leaking through when open, thanks to small a flap inside each. The inflate valve’s flap popped out of place once, but I only had to push it back in to repair it. More uniquely, it deflates in about a half-second when you open that valve, making packing up a quick task. It takes me about 25 strong breaths to fully inflate the mattress. The water-resistant, synthetic Primaloft insulation, packed into baffles, delivers an R-value of 3.2, comparable to other high-quality, three-season air mats. The insulation is also relatively quiet, not squeaking loudly when I roll around, like some other air mattresses—probably a relief for my tent mates.

    Michael – Thanks for your review. I had drecently purchase the REI Flash mattress and have also found it to be a great, lightweight sleep aid. I would like to know what chair kit you were using that worked with the Flash. I can’t get it to fit in my older Thermarest chair kit.

    Great timing Michael. Chris and I were about to throw in the towel on tent camping as our old bodies were aching after sleeping on our sleeping pads. I’m going to buy a couple of these and give tent camping another whirl.

      Good to hear that, Alisa. You guys can’t give it up yet! Besides, I thought Chris was a fan of suffering outdoors.
