Sea to Summit Ascent Down Sleeping Bag - Best Summer Gear
Sea to Summit’s Ascent Down Sleeping Bag was chosen as part of our Best New Hiking/Camping Gear of 2024—to see the entire list click on over here.Sea to Summit has redesigned their men’s and women’s Ascent Down Sleeping Bags for Spring 2024 and they’ve added a few new features that make it one of the most versatile and functional 3 season sleeping bags on the market. The Ascent’s warmth comes from the bag’s RDS-certified 750+ fillpower goose down which uses a non-PFC Ultra-Dry Down treatment to ensure the down stays drier in damp conditions. This is wrapped up in a lightweight 20D recycled nylon shell with a non-PFC Durable Water Repellant (DWR) finish to ensure wind and water don’t penetrate the outer fabric. On the inside of the Ascent Sleeping Bag, you’ll find the same super soft and comfortable 20D recycled nylon. Sea To Summit uses a box baffle design that keeps more of the warmth within the bag since the stitching is not sewn through. This process takes considerably more effort to produce but the added warmth and comfort are immediately noticeable. On the lower half of the bag, the baffles run vertically up and down to minimize migration of the down and maximize the warmth transfer down your body while the upper baffles are a more traditional horizontal orientation to promote heat distribution across your torso.
Sea To Summit’s unique Free-Flow Zip System means that you have several ways to stay comfortable depending on your sleeping preference and body temperature. You can open up the side zipper to vent out excess heat or use both side zippers to increase ventilation and airflow to prevent overheating. You can even unzip the foot box zipper to release heat from that area as well. If you prefer you can unzip the main zipper fully to use the Ascent Sleeping Bag as a quilt or simply snap the top of the side zippers and then open up the zippers enough to poke your arms out and use the foot box zipper to poke your feet out and you can relax in your tent staying warm and comfortable while still having all the mobility you need. The Free-Flow Zip System also allows you to seamlessly couple together two Ascent Sleeping Bags to maximize interior space, heat sharing and comfort. All of the zippers have interior baffles to prevent heat loss and the two side zippers used anti-snag zipper plows to ensure that you will never snag the fabric when closing the zippers. Brilliant!
This is the one three-season bag you’ll ever need no matter the conditions or your adventure, full of innovative design features and an impressive warmth-to-weight ratio making this our sleeping bag of choice.
