Why We Like The Sea To Summit Spark Sleeping Bag
The Sea To Summit Spark 15-Degree Sleeping Bag keeps our pack light and offers plenty of reliable warmth for backpacking trips through the early parts of winter. The lofty 850-fill down has a hydrophobic Ultra Dry Down treatment to maintain warmth in cold, damp conditions. The bag is exceptionally warm, especially considering that it weighs just over two pounds, and the mummy shape maximizes thermal efficiency on cold, frosty mornings. The three-quarters length zipper is protected by a down-filled draft tube to eliminate cold spots, and the hood and footbox are protected by a DWR coating to ensure the down stays lofty even if our tent gathers condensation.

Amazing
[This review was collected as part of a promotion.] Let me nephew borrow this and he said it's super comfortable and really liked the way it feels and how easy it was to put away! Makes me excited for camping this summer!

A nice light sleeping bag!
[This review was collected as part of a promotion.] I received this sleeping bag from influenster in return for an honest review! We went camping in the sequoia national park, and I brought this sleeping bag to test it out! First of all it’s a nice looking sleeping bag, and it is very soft and light. It doesn’t take up a lot of space, and is easy to roll up and put away in the bag it comes in. I did sadly freeze in the night, but it was cold when we went, and was about to snow the day after, so I’d say this sleeping bag is more for a barn spring or summer use! I think this says to be good down to 7 C or like 45 F, but I think it was around 30s F when we were camping. I was wearing two blankets on top but was still cold on my back and toes and legs. I liked that the zipper is both reachable on the outside and the inside of the bag, and that the head piece can be tightened a lot, I tightened it so only my mouth was sticking out, to try and keep warm. Also the bag is pretty roomy, I was able to sleep on my side in it! Overall it’s a great sleeping bag, you just have to be mindful of how cold it is where you’re going to camp!

Soft & lightweight
[This review was collected as part of a promotion.] It hasn’t gotten cold enough to see if it keeps warm, but it’s super comfortable and cozy and I’m a little bit on the bigger side. It’s a little snug but still comfortable! Perfect for camping sleepovers or just something cozy for an emergency

Lightweight Warmth
[This review was collected as part of a promotion.] Wow. This sleeping bag from Sea to Summit is amazing. It’s super lightweight and very easy to compress and pack into a small size. It is very form fitting and snug, but it definitely does the job of keeping you warm and comfortable.

Premium Quality and Comfort
[This review was collected as part of a promotion.] Our family has owned several sleeping bags throughout the years but the quality of all of them combined does not even come close to the quality of this Sea to Summit sleeping bag! With a mummy shape designed for a woman, it contours to my body leaving no room for cold air to make its way inside. The zippers are snag proof and the water repelling nylon fabric is soft, smooth, and breathable. (I still plan to purchase one of their silk-blend liners to keep the bag clean inside.) It’s incredibly lightweight- easy to fold, carry, and store; perfect for backpacking. Despite its weight, the 850+ PFC free ultra-dry down fill keeps you warm in 15°F freezing temperatures. In the past, I never would have considered spending over $500 on a sleeping bag until I received this one as a gift in exchange for my review. I’ve since ordered a regular one for my hubby.

Love it!!
[This review was collected as part of a promotion.] So soft and durable. It packs up in a small square that will barely take up any room. It feels super warm and uniquely fitting to my body. It’s perfect !

High end experience!
[This review was collected as part of a promotion.] This sleeping bag is INCREDIBLY comfortable! It’s made of down goose feathers and high end. This is the first sleeping bag made for women that adequately hugged my curves and gave me a good night sleep. I packed it up with minutes and was ready to go back on my hike! Entirely worth its price point!

So soft!
[This review was collected as part of a promotion.] Right off the bat I was super impressed with how lightweight this sleeping bag was. I was a little hesitant as to how warm it may be because it’s so thin, but WOW! It’s so warm yet not too warm. It’s very very soft and fits perfectly in the small bag it came with! Very impressed!

Very good quality
[This review was collected as part of a promotion.] I love camping and hiking trips and visited most of the US National and State parks. Couple years ago when we did our camping trip with it snowed at night and I thought I will freeze to death, becauseI found out that my sleeping bag wasn’t warm enough for that weather. Since then I avoided going camping in autumn and wished I had a warmer sleeping bag. As a person who is always cold, I am so happy with this -9 C Women’s Regular size sleeping bag. It is down filled, very warm and made of very nice quality materials. Easy to pack, comes with two storage bags. Has lifetime warranty.

Good luxury feel sleeping bag. Kinda thin.
[This review was collected as part of a promotion.] The material feels extra luxurious. It’s powder soft and warm. It was made to fit the contour the woman body shape so it fits perfectly, kinda long for me because I’m short but it doesn’t matter. But i think it’s really thin so I think I have to buy a sleep liner if I want to feel more comfortable to sleep on the ground.
