Light, warm, comfortable and most importantly, adaptable. Offering the perfect backpacking balance of comfort vs weight. The Altitude™ features extra down overall and THERMOLITE® panels under the foot area, to help keep heels and ankles warmer. The women’s specific fit is wider at the hip and narrower at the shoulders.
This bag has a tapered rectangular shape which is roomier than a mummy bag but will still keep you warm. You can adjust this design depending on the conditions thanks to the free-flow triple zips.The half zip on the right side of the bag provides freedom of movement for both arms, additional ventilation or fold the top third of the bag down as a mini quilt.
The full length, two-way left side zip and separate foot zip transforms the bag into a full quilt for when the temperature climbs higher than expected.If it’s warmth you want, close up all the zips, pull the cord locks tight to drag everything in, and relax in luxurious comfort.
Filled with R.D.S certified 750+ loft down providing great insulation, and the oversized draft tubes prevents loss of body heat. Vertical baffles over the chest area ensure the down cannot migrate or shift during sleep,creating cold spots. The paneled footbox and 3-dimensional hood ensure you’re not compressing the down when you’re trying to stay warm. A side block baffle construction maintains the 60/40 fill ratio, keeping more down on the top of the bag for maximum insulation.
The ULTRADRY Down™ protection also makes the Altitude™ an impressive hard-alpine or adventure racing bag, where every gram is counted and down has never been a viable option. All Sea to Summit Down Sleeping Bags use Responsible Down Standard (RDS) certified down.
