The NEMO Tango Duo Slim 30 Sleeping Bag is an ultralight solution for two campers or backpackers. Packed with 700-fill down, this bag delivers high-loft warmth and compresses into a small package for storage. The DownTek™ down features a water-repellant treatment that will help maintain thermal efficiency even if your bag is exposed to wet or damp conditions. The bottom of the bag foregoes insulation and instead has an integrated pad sleeve that accommodates two 20 inch wide sleeping pads. This design contributes to weight savings you and prevents you and your partner from sliding around on your pads throughout the night. In warmer weather, unsnap and untuck the bag to use it like your comforter at home.
