The new Haven Sleep System provides ounce-counters with the ultimate synergy between mattress and bag, challenging the convention that you have to sacrifice comfort to travel light. It's unique, zipperless design takes advantage of inherent mattress warmth, eliminating unnecessary insulation between mattress and sleeper. The resuling weight savings combine with a full-coverage design, premium 700-fill down and multiple mattress integration options to deliver a EN-13537 rating of -6C (20F), an impressive 625g (1lb 6oz) weight for regular size, and a new standard of ultralight comfort on the trail. Fits any rectangular mattress with or without lightweight and easy to use straps (included); allow added ventilation options in warmer weather. Tapered Prolite and ProLite Plus mattresses fit easily inside to provide better cold-weather performance; elasticized opening for easy entry/exit and minimal drafts and eliminates zippers and unnecessary fabric and fill beneath you. Full hood and total coverage allows true cold-weather performance without added gear and the enclosed foot box retains maximum heat where it's needed most. Dimensions: Fits up to 178cm (5'10") Weight: 624grams (1lb 6oz)
