User Review: Big Agnes Insulated Air Core
Price Paid: $60-ish
Extremely comfortable. I've used closed-cell foam, then self-inflating pads, and then this one, and the amount of comfort is amazing. I camp mostly early to late summer, and have not had issues with coldness. Once it felt a little chilly, but I just blew more air into it and it was fine.
Bottom line, if you camp in the cold, you need to augment this pad with a closed-cell pad underneath. Big Agnes skimped on the insulation - there's very little to insulate. As long as you do not depend on this pad to keep you warm in colder temps, you'd probably love it. I had always slept brokenly in the wild until I got this pad. Very very peaceful.
