When you're bicycle touring cross country, paddling for a week in the Boundary Waters, or backpacking Isle Royale, space and weight are at a premium. Bring along the Marmot NanoWave 45 Sleeping Bag, and stay comfy at night without contributing to any back crushing weight during your daytime travels. This lightweight yet durable bag uses high loft Spirafil 100 synthetic insulation to keep you warm on chilly summer nights. You might be tempted to think that, at less than two pounds, the NanoWave skimps on features of convenience and functionality. Have no fear Marmot created this easily packable bag while still focusing on the details. Blanket construction, a snagless draft tube, two way zipper sliders, and a zipper garage all contribute to comfort and convenience. Expertly designed features like feely drawcords and hang loops prove that Marmot's designers have been out there and know what features adventurers like you want.
