The Sea to Summit Venture Women’s 32-Degree Synthetic Sleeping Bag is a versatile bag for 2-season backpacking. The mummy style cut features a shaped hood, draft collar, and zipper draft tubes to keep the cold out and the warmth in. Thermolite insulation, with its proprietary blend of hollow-core fibers for lightweight warmth, and compressibility, fills the WaveLoft construction pattern, which maximizes loft, expanding the fill to trap air for maximum warmth. The women’s-specific design features shorter length and narrower shoulders to increase thermal efficiency and allow for a natural sleeping position; insulation is mapped to a woman’s physiology to maximize warmth. Snug and cozy in the cold, the triple zipper system cools things down when temperatures rise: full-length zippers on each side, as well as a footbox zip can be opened for ventilation; can be completely unzipped for use as a comforter. Bag can also be zipped to a Sea to Summit Ascent, Trek, or Traverse sleeping bag. The shell is made from DWR-treated 30D nylon. The Sea to Summit Venture Women’s 32-Degree Synthetic Sleeping Bag is available in two sizes: Regular (max user height of five feet seven inches), Long (max user height of six feet). Includes 70D nylon compression sack. Sea to Summit products are guaranteed against defects in materials or workmanship for the lifetime of the product.
