● Tested by an independent third-party lab using European Norm protocol, the EN temperature ratings allow direct comparisons across brands with other EN-rated bags

● Synthetic Thermawave polyester insulation is durable and highly compressible; synthetic polyester fill retains some insulating properties even when wet

● Shingle construction with overlapping layers distributes insulation evenly and keeps it from moving around so there are no cold spots

● Equally distributed insulation accommodates the multi-position sleeper; mummy shape is thermally efficient, yet roomy enough to ensure sleeping comfort

● Ripstop nylon shell fabric has a nice hand feel, is lightweight, durable, water- and abrasion resistant; nylon taffeta lining is soft and tear-resistant

● Relaxed fit through the shoulders and hips gives you room to move for a better night's rest

● Contoured hood, insulated full-face muffler, roomy footbox and full-length zipper draft tube with ground-level seams work together to keep heat in and cold out

● External chest pocket keeps small essentials—headlamp, watch, glasses—right at hand and easy to find in the dark

● Special pocket in hood can be stuffed with clothing layers to make a pillow that stays in place; no need for a pillow to take up valuable space in your backpack

● Pad loops provide attachment points to keep your sleeping bag and pad together, so you needn't worry about rolling onto the cold ground (straps sold separately)

● Full length zipper is backed by wide, antisnag binding tape

● Differentiated drawcords (1 round, 1 flat) allow quick identification, even in the dark, so neck and hood adjustments are a cinch

● Nylon stuff sack and cotton storage bag included
