FEATURES of the Big Agnes Air Core SL Air Pad.
SPECIFICATIONS of the Big Agnes Air Core SL Air Pad.


The superlight Big Agnes Air Core SL sleeping pad is a half inch thicker and several ounces lighter than the standard Air Core pad, keeping your pack light and offering great comfort for sound sleep.


The Air Core SL from Big Agness is a superlight version of the regular air core. A compact, durable pad, made from durable rip-stop nylon top and bottom, the Air Core SL has an estimated R-Value of 1 with internal heat reflective polyurethane coating.

Size matters: the thick and comfy Big Agnes Air Core SL Sleeping Pad offers more airy cush than self-inflating pads, and its rectangular shape gives you more room for tossing and turning when your tent-mate is sawing logs. An internal heat-reflective coating and I-Beam construction that gives consistency and stability ensure efficient comfort, even when the temps drop to near-freezing. Rest your heavy eyes in superlight comfort.

I'm 6'5'' 260lbs. I needed a pad that not only was long enough, but also thick enough it would hold me up to where I'm not touching the ground. So I bought the long/wide, and I couldn't be more thrilled! Its super light, durable rip-stop looking(but slippery) material, and rolls up tightly to the size of a full stock of celery (thought I'd compare to something other than just specs). It does take abit of huffing and puffing to get it aired up, but the "work" for comfort trade off is WELL worth it! For those of us taller folk, (for reference) with my head on the pillow my heels are an inch from the end, and laying on my stomach my toes curl over the end. I'm sooooo thankful I got the wide version as well because my arms rest just perfectly on the mat with 1/2" left on either side. I haven't yet used it out in the field, but will be sure to update when I do.

This pad made my nights on the hard bunks of the AT shelters much more comfortable. Plus its lightweight and small packing size made it all the more appealing. It is a little loud at night with its crunching sound, but that has been typical for similar pads. I also wish it was a hair wider. All in all, it is a great product.

Negative Reviews:

You would think extra thickness translates into a more comfortable pad, but that's not what I found. I am 6'4'' with a slim build but broad shoulders, but have slept comfortably on 20" pads before.
The issue with this pad is that because it's so thick, if you arms hang off the sides at all they have a long way to go. This ended up being really painful on the shoulders after a whole night of dangling arms and alternatively trying to hold them back on the pad.
This pad could work fine for someone with a smaller build, but if you find any part of your arms coming off a 20" wide pad, it likely won't.
