DEMO Sea To Summit | Ascent Down Sleeping Bag 15°F


DEMO UNIT products are gear items we have personally used for making product videos/photos, store displays, and used at shows. These items are generally used once or twice. These items are possibly a little dirty and show signs of wear and may not come in original box or package, but will include everything and are not missing any pieces. These items are in good working order and are discounted due to being used in house and discontinued

The Ascent down sleeping bag is a relaxed mummy style that redefines what versatile means in a sleep system. Complex construction and high-quality down keep you warm when it’s cold outside, while the triple-zipper Free-Flow Zip™ system ensures you stay cool and ventilated when the weather warms.

Shaped to allow a natural sleeping position for comfort, the Ascent is light and compact enough to go everywhere your adventures may take you.


  • 3 Season: 15°F (comfort range 15°F to 65°F)


  • More room between hips and knees to allow you to sleep in a natural position without compressing the down insulation and creating cold spots. Far more comfortable than narrow mummy bags for most sleepers.


  • ULTRA-DRY Down 750+ Loft 90% Down Cluster Premium Duck Down certified Responsible Down Standard (RDS)
  • Free-flow zipper system: full-length YKK® #5 main side zip, half-length opposite side zip, and foot zip provides unparalleled ventilation and use as a comforter.
  • Vertical baffles over the chest to prevent down shifting as you roll over in your sleep.
  • Shaped hood, oversized draft collar, and zipper draft tube keep the cold out and the warmth in.
  • Internal pocket for phone / GPS / valuables.
  • Form a snug double sleeping bag by zipping to any Altitude™, Journey™ or Venture™ sleeping bag.
  • Includes lightweight Ultra-Sil™ compression bag and storage cell.
