A quilt for the minimalist adventurer.

Sea to Summit's Ember EB I Sleeping Bag is more of a quilt than a bag, and its zipperless design gives the ultralight, ultra-compressed convenience that minimalist backpackers, alpinists, and touring cyclists need. Ultra-Dry Down 750+ insulation gives this quilt a phenomenal weight-to-warmth ratio that only weighs around a pound and stays warm enough for summer trips.

Sea to Summit treated the Ember's down insulation to resist moisture, remain lofty, and retain its warmth in humid, moist conditions. The quilt's bottom has a drawcord and press studs to create a snug footbox so your legs don't slip out in the middle of the night. Four adjustable straps secure your sleeping pad so you don't slip off halfway through the night.
