STAFF PICK - Sleeping Bag: With good reason the Therm-a-Rest Thermarest Hyperion 20F Sleeping Bag was our top pick for an ultralight sleeping bag. it is one of the very lightest 3-season bags on the market. Not surprisingly, it has the best weight to warmth ratio of all the sleeping bags we looked at! This is achieved through the use of 900 fill power down, a relatively lightweight shell fabric (10D compared to 15-20D for some other bags reviewed here) and a snug fit.

GREAT FOR: One of the lightest and warmest all around sleeping bags on the market.
