Bantamweight 15 Sleeping Bag - Men's

About this find

This Marmot Bantamweight 15 is a men's down sleeping bag made for backpackers who count every ounce. The Short center zip size weighs 1 lb. 6.3 oz. and holds 1 lb. 0.2 oz. of 900+ fill-power goose down. The down is treated with Down Defender to improve water resistance in wet conditions. Both the shell and the lining are 100% nylon ripstop, and the center zipper on the front makes getting in and out easy.

The slim mummy shape reduces weight and increases thermal efficiency. This size fits people up to 66 inches tall, with a 57 inch shoulder girth and a 52.4 inch hip girth. Smooth, curved baffles reduce down shifting, and the drawcords cinch the hood around your head. The bag is rated to 15 degrees F (-9 degrees C) by the ISO tested Lower Limit, and its ISO tested Comfort rating is 26 degrees F.

A compression and storage sack is included. The stuff sack measures 6.3 x 12.6 inches and holds 6.4 liters, and the bag compresses down to 5.4 liters, so it takes up little room inside a pack. Temperature ratings are a guideline, not a guarantee of warmth. The ISO tests use one base layer, a pair of socks and an insulated pad with an R-value of at least 5.38. Pair this bag with a well insulated sleeping pad to get the most from its rating.
