That's what grabbed me here. I can save 15 ounces for the additional investment of about $80 if I return my brand new Big Agnes Insulated Air Core to REI. 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...
