Thermarest Haven

An Ultralight, Zipperless Sleeping Bag. Thermarest have essentially removed the entire bottom of the sleeping bag, together with the zippers. Instead of insulation on the bottom, the Haven works in conjunction with a sleeping pad, eliminating reduntant material underneath and therefore cutting weight to 1 lb 6 oz. The Haven secures to any sleeping pad using built-in straps on back and can also be used without a sleeping pad in warmer weather. The Haven Top Bag provides serious ounce-counters with the ultimate synergy between mattress and bag, challenging the convention that you have got to sacrifice comfort to travel light. Its unique, zipperless design takes advantage of inherent mattress warmth, eliminating the need for redundant and unutilized insulation. The resulting weight savings, premium 700-fill down and versatile mattress integration options create an EN-certified warmth rating of 20F (-6C), an impressively sleek 1lb 6oz (624g)* weight, and a new standard of ultralight comfort on the trail.

Ultralight Warmth: Eliminates zippers and unnecessary fabric and fill beneath you to achieve EN 13537 -6C (20F)-rated comfort at just 22 oz (624g).
Technical Performance: Durable 20D nylon shell, and 700-fill down combine with a full hood, modified foot box and wrap-around coverage to provide reliable warmth with minimal draft.
Exceptional Versatility: Can be strapped to any mattress, used on top in warmer weather or slip a tapered ProLite or ProLite Plus mattresses inside for maximum cold-weather performance.
Unparalleled Comfort: No more sleeping like a mummy, trying to find out which way is up, or searching for your zipper - they’ve delivered room where you want it without excessive gaping for maximum efficiency.
