Sea To Summit Ascent

The Ascent series delivers the optimal balance between comfort and weight. The special design offers more space than traditional mummy-shaped sleeping bags. Nevertheless, the Ascent guarantees excellent thermal efficiency and can be used without hesitation on tours above the tree line. With the unpredictability of weather and nature in mind, the Ascent series has been designed to be the most flexible sleeping bags in the range.

The Free-Flow Triple-Zip system ensures high thermal performance and efficiency, offering versatile ventilation settings. The half-zip on the right side and the full-zip on the left side provide enough free space for both arms, allowing the top third of the sleeping bag to be folded down like a blanket. When temperatures rise higher than expected, the sleeping bag can also be opened up into a blanket through the full-sided two-way zipper and the additional zipper in the foot area. If you want warmth, close all zippers, pull the cords together, and relax in luxurious comfort.

The generous use of high-quality 750+ loft down provides excellent insulation. The large-sized zipper channels prevent body heat from escaping. The specially shaped footbox and three-dimensional hood ensure that you don't compress the down. The separate vertical chambers with 60/40 down ensure that the down on top does not slip sideways, providing maximum thermal insulation in the upper body area.

Despite the generous cut, the Ascent does not compromise on weight and pack size. The ultralight 20D shell and perfectly matched design features, along with the high-quality down, allow the sleeping bag to compress impressively compact and stow in the included Ultra-Sil compression sack.

Lightweight, warm, comfortable, and above all versatile, the Ascent is the most flexible sleeping bag in the range and the ideal choice for a variety of activities and weather conditions.
