DESC: Backpacker April '08 proclaims the Marmot Atom bag is ''sleep-anywhere evidence that luxury and lightweight can go hand in hand.''. One of the sweetest, lightest bags out there, this Marmot masterpiece is for fast, light summer trips. Lightforce nylon shell is lightweight yet strong; a Durable Water Repellent finish causes moisture to bead up and roll off. Premium-quality 850-fill-power goose down is extremely compressible and offers an exceptional warmth-to-weight ratio. Face muff allows hood to be cinched snug without digging into your face. Down-insulated draft tube backs full-length zipper to keep the cold out. Zipper guards prevent zipper snags; locking zippers keep bag from opening if you toss and turn at night. Classic trapezoidal foot box lets your feet move freely and comfortably, and allows goose down to loft fully to keep your toes toasty warm. Stuff sack and storage sack included.
