Sea To Summit Ascent -9C 185 (ASL041101-212004)

The Sea to Summit Ascent lightweight backpacking bag impresses us with its premium down, relaxed mummy shape, and versatile zipper system. It features 19. 4 ounces of responsibly sourced, 750-fill duck down that's treated with a durable water repellent to minimize the risk of moisture ruining our bag's lofty insulation. Vertical baffles in the ches... moret prevent the insulation from shifting away from our core while an oversized hood and draft collar seal in our body heat to keep us safe down to 15 degrees. We also like the relaxed mummy shape, which gives us a little more to room while still minimizing weight and bulk for easier packing. Finally, the bag's Free-Flow trip zip system lets us fold down the top third of the bag for maximum ventilation, ventilate our feet, open the bag fully for more comforter-like use, or pair with women-specific right-hand zip models, such as the Sea to Summit Altitude, Journey, and Venture sleeping bags.
