Questions, Answered

Is it a one-time use emergency blanket?

No. Unlike foil blankets, this is a reusable bivy sack with a full-length zipper. Used with care it survives dozens of outings.

How warm is it really?

It reflects about 90% of radiated body heat. It is not a replacement for a sleeping bag in deep cold; it is the layer that keeps a bad night survivable.

How small does it pack?

Roughly the size of a deck of cards, 3.5 oz. It fits in a jacket pocket, glove box, or the bottom of any pack.
