Does exactly what it's supposed to do.Review by Vern
The Vireo UL does exactly what it's supposed to do - keep you warm in moderate temperatures when combined with other warm clothing.

Last year I used this bag extensively around the Canadian Rockies including 2 nights on an icefield - http://www.explor8ion.com/climbs/brazeau.html. This bag is so light and packs so small you don't know it's there, which is the entire point! I combined it with a NeaAir XLite sleeping pad and only wished I'd brought my 800 fill down jacket, which I forgot since it was mid summer.

I like the Vireo so much, I just ordered a Snowbunting bag for winter use. (Posted on 3/4/2016)
