  • Features

    • With a European Norm (EN) lower-limit rating of 20°F, this bag is suitable for 3-season use
    • Synthetic polyester insulation is durable and highly compressible; the fill also retains some insulating ability if it gets wet
    • Shingle construction with overlapping layers distributes insulation evenly and prevents cold spots
    • Equally distributed insulation accommodates the multiposition sleeper; mummy shape is thermally efficient, yet roomy enough for sleeping comfort
    • Durable ripstop nylon shell is water- and abrasion-resistant; nylon taffeta lining is soft and resists tears
    • Relaxed fit through the shoulders and hips gives you room to move
    • Contoured hood, insulated face muffler, roomy footbox and full-length zipper draft tube work together to keep heat in and cold out
    • Bag has a stash pocket under the collar
    • Pad loops provide attachment points to keep your sleeping bag and pad together (sleeping pad not included)
    • Full-length zipper is backed by wide, antisnag binding tape
    • Differentiated drawcords (1 round, 1 flat) allow quick hood and neck adjustments in the dark
    • Nylon stuff sack and cotton storage bag included

    Many sleeping bags are rated for temperature by an independent testing protocol. With both European Norm (EN) 13537 and International Organization for Standardization (ISO) 23537 testing, each bag gets a Comfort (or T-Comfort) rating and Lower (or T-Limit) rating. The Comfort/T-Comfort rating is the lowest temperature at which the bag will keep the average "cold sleeper" comfortable, and the Lower/T-Limit rating is the lowest temperature at which the bag will keep the average "warm sleeper" comfortable. Ratings are based on a person wearing one long underwear layer and a hat, sleeping on a single 1 in. thick insulating pad. Many brands use the Comfort rating for women's bags and the Lower rating for men's and unisex bags. Everyone's body and sleep comfort differ, so EN and ISO ratings are simply a guideline to help you compare products.
