"Since the Air Core is not self-inflating, it takes some effort
to blow up--typically 4 minutes of puffing"
[also the lack-of-insulation problem]

Of what material is the Big Agnes Air Core mattress constructed?
I've never liked the feel of air mattresses (or water beds) but
friends who like air mattresses are often disappointed when their
air mattress pops on the first night out!

Thermarest has two new models, with lighter foam and fabric, and
a tapered design. The Prolite 3 weighs only 1 lb 4 oz, same as
the regular size Air Core, and is supposedly just as comfortable
as the original 1.5"-thick Thermarest.
