The Sea to Summit Journey Women's 30-Degree Down Sleeping Bag is a versatile down bag, ideal for backpacking, trekking, and traveling in a variety of temperatures and conditions. The mummy style features a shaped hood, oversized draft collar, and zipper draft tube to keep the cold out and the warmth in. Compressible 650 fill power down insulation (Responsible Down Standard certified) is treated with proprietary ULTRA-DRY Down to improve reaction to moisture, retaining loft and performance in rugged conditions. A Thermolite insulated footbox provides instant warmth for the feet. The women's specific design features shorter length options, and narrow shoulders to eliminate dead space and increase thermal efficiency; down chambers are mapped to a woman's physiology to maximize warmth. Snug and cozy in the cold, a full-length left-side zip, and foot zip can be opened for ventilation or to turn the Journey into a comforter. Bag can also be zipped to the Sea to Summit Ascent, Trek, or Traverse sleeping bags. The shell is made from durable 30D nylon, and an internal pocket holds small essentials.
