REI Co-op

Features

1. 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
2. Women-specific bags are cut to mimic a woman's shape for optimal thermal efficiency
3. There is more insulation in the women�s Lumen than the men�s Lumen to account for metabolic differences in gender so women are comfortable at the same temperature
4. Synthetic Thermawave polyester insulation is durable and highly compressible; synthetic polyester fill retains some insulating properties even when wet
5. Shingle construction with overlapping layers distributes insulation evenly and keeps it from moving around so there are no cold spots
6. Equally distributed insulation accommodates the multi-position sleeper; mummy shape is thermally efficient, yet roomy enough to ensure sleeping comfort
7. Relaxed fit through the shoulders and hips gives you room to move for a better night's rest
8. Ripstop nylon shell fabric has a nice hand feel, is lightweight, durable, water- and abrasion resistant; nylon taffeta lining is soft and tear-resistant
9. 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
10. External chest pocket keeps small essentials—headlamp, watch, glasses—right at hand and easy to find in the dark
11. 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
12. Full length of zipper is backed by wide, antisnag binding tape
13. Differentiated drawcords (1 round, 1 flat) allow quick identification, even in the dark, so neck and hood adjustments are a cinch
14. Nylon stuff sack and cotton storage bag included
