Here's what other sites are saying:
A light weight housing for 32 oz. Nalgene round bottles. Insulated with closed-cell foam and fleece in a packcloth outer shell, keeps water liquid over night at 20 below. Web grab loop is large enough to provide a quick handle even with mittens, doubled down one side for strapping to belt, pack, or sled. Has a #8 coil zipper that resists icing but provides easy access. Use in warmer months to keep beverages cool. Weighs 5 oz. Made in USA.
