Why We Like The Sea To Summit Ascent Sleeping Bag

The Sea To Summit Ascent Sleeping Bag is as adaptable as it is comfortable, right at home at shady summer campgrounds and setting up camp after a long trek on weekend backpacking trips. The relaxed mummy gives us more room than most mummy bags, and the Free Flow Zip System offers ventilation on both sides of our torso and at the footbox for ultimate comfort. The lightweight 750-fill duck down is treated with a hydrophobic Ultra Dry Down finish to ensure tent condensation and wet campsites don't sap the warming power of the down, and the draft tubes and collar keep warmth centered around our core.

[This review was collected as part of a promotion.] This is a super comfortable bag! Normally, I’m incredibly uncomfortable with a sleeping pad and bag, but the Ascent bag was so cozy! Kept me warm through the night, and the zip downs on the side were great for preventing overheating. It’s a bag that feels nice to slip into after a long day of hiking, and at around one pound, didn’t add to much to my pack. I’m excited to keep using this for the season.

Comfy and warm

[This review was collected as part of a promotion.] I Love the shape of this sleeping bag and that it’s made for a female body and stature. Can’t wait to take it fall camping , and am excited to break it out this summer. It’s compact and easy to bring along on the road.

Green with Backpacking Envy

[This review was collected as part of a promotion.] I am so excited to have received this sleeping bag! I plan on using it for our upcoming Yosemite trip. The color has two variations of green, which looks great and very eye catching. The durability of this sleeping bag is amazing and I know it will last multiple backpacking trips. The bag it comes in has two handles, making it easy to attach to my backpack using a carabiner at the top. It's super light, and I can roll it even tighter if needed, which is a huge plus for longer hikes. I was able to test it out in my living room and it has just enough space to not feel claustrophobic but keep me warm. The amount of down filling is impressive and I’m looking forward to a comfortable night's sleep after a long day of backpacking Yosemite!

Really incredible sleeping bag

[This review was collected as part of a promotion.] I am in love with this Sea to Summit sleeping bag. It’s the Ascent Women’s Down bag. The color is pretty and I like the aesthetic. It’s super portable. The bag is easy to carry. It can pack down small and is super light. I like all the zipper features. It’s cool that you can zip up but still leave your legs and arms sticking out. It’s very warm inside. The hood is nice as well. The size is perfect for me. Overall this bag is great and I would recommend.

Compact, warm and well made- extremely durable construction

[This review was collected as part of a promotion.] I received a free Ascent Women’s down sleeping bag by seatosummit in exchange for my honest review. This sleeping bag is extremely well made. The material is so soft and the weight is light as well for backpacking. This is rated to keep you warm in as low as 15 degrees Fahrenheit. The weather near me was not that cold but it is very warm and comfortable. The design is well thought out and I especially like how the head area curves in and can be tightened to keep out the cold. This sleeping bag is the regular size and is large enough for a woman that is 5’7’’. With that being said, I am 5’10 and I weigh 175lbs. Although I am past the recommended height restriction, I was still able to fit in this sleeping bag. My toes were right up against the bottom but it wasn’t uncomfortable. I assume that the long would be even more comfortable for my body type. The color is nice and reminds me of an avocado- dark green on the outside and light green on the inside. There is also a well thought out pocket on the inside for small items such as a phone or keys. For such a warm sleeping bag, I am super impressed with how small it can be folded into. This would be a fantastic addition for any serious hikers/campers who are looking to stay warm after a long day of hiking.

Soft and fluffy

[This review was collected as part of a promotion.] This sleeping bag is so soft and comfortable! It feels like your bundled up in clouds. It’s feels well insulated and it’s easy to pack and unpack from its bag. It’s a pretty 2 tone green color and I’m sure it will keep me warm camping on chilly nights!
