Why We Like The Sea To Summit 30 Down Spark Sleeping Bag
For ultralight backpackers, adventure bikepackers, and everyday campers, the Spark 30 Down Sleeping Bag is here to provide a comfy night's sleep in a super lightweight package. Sea to Summit stuffed it with 850+ fill power goose down for the best possible warmth-to-weight ratio while also keeping us cozy in temps down to 30°F, and gave it an Ultra Dry Down treatment that maximizes thermal performance even when wet. The ultra-light, breathable 10D nylon shell and lining shed even more weight while adding durability, while the full hood and anatomic footbox wrap around the head and feet, respectively, without the claustrophobic feel of other ultra-light bags.

Warm and cozy
[This review was collected as part of a promotion.] The Spark Down Sleeping Bag is exceptional! I tried it out and was so impressed with the comfort and warmth! It packs down very small for something that keeps you so warm! I am a tall girl and it is long enough and comfortably roomy. Love the yellow and grey color!!

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.

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.
