Description
The Sea to Summit Ascent 0-Degree Down Sleeping Bag is a high-performance, versatile down bag, ideal for backpacking 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. High-loft, 750 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. The relaxed mummy shape offers more room between the hips and knees for a natural sleeping position, while vertical baffles over the chest prevent the down fill from shifting during sleep. Snug and cozy in the cold, the Free-Flow Zip System cools things down when temperatures rise: a full-length left-side zip, half-length right-side zip, and foot zip can be opened for ventilation or to turn the Ascent into a comforter. Bag can also be zipped to the Sea to Summit Women’s Altitude, Journey, or Venture sleeping bags. The shell is made from lightweight 20D nylon, and an internal pocket holds small essentials. The Sea to Summit Ascent 0-Degree Down Sleeping Bag is available in two sizes: Regular (max user height of six feet) and Long (max user height of six feet six inches). Includes Ultra-Sil compression sack. Sea to Summit products are guaranteed against defects in materials or workmanship for the lifetime of the product.
