They're quite new and it might be they can't yet supply the volume REI requires. BackcountryGear lists them as available, so they're at least out. No way to test in-store, though (unless you live in Eugene).

I'm dubious about the BA insulate Air Core being nearly R-5. Mine doesn't seem any warmer than the standard NeoAir, and is not as comfortable.

p.s. How is it the regular is six inches longer than the medium--same width--and weighs a scant one ounce more? Seems unpossible.

Cheers,

However, they only seem to carry the regular NeoAir - it only has an R value of 2.5, compared to 4.1 for the Big Agnes Insulated Air Core or 4.9 for the All Season NeoAir. Comparatively, I can save a pound on a tent for about $200, or about 5 lbs on a pack for about $200. Really, it's an opportunity to not get stuck in a sunk cost on the Insulated Air Core.

Thanks for all the help...
