Why We Like The Sea To Summit Spark 30F Down Sleeping Bag
As the forest reawakens to springtime rains, and the sun shines just a bit warmer on our faces, we pack our Sea To Summit Spark 30F Down Sleeping Bag on our first fair-weather camping trips of the season. The powerful 850-fill down provides consistent warmth from the first warm nights of spring through the final trip of the fall, allowing us to sleep beneath the stars in comfort. The hydrophobic down and DWR treatment on the lightweight nylon ensure reliable warmth, even after spring showers and summer thunderstorms, and the bag packs down small so we can bring it on every trip.

Almost perfect
[This review was collected as part of a promotion.] I really like the compressibility and weight of this bag. Just what I need for the fall and spring in my area. My only complaint is that the zipper is on the left, which I can't get used to. The door of my Alto TR1 is on the right (as well as most other single door tents) and so is the storage pocket. I am used to being able to unzip the bag a bit and access the door of my tent and the pocket for my phone ect. I can still get to these things but I would prefer the zipper on the right like all my other sleeping bags.

Excellent product
[This review was collected as part of a promotion.] This sleeping bag is well made and very functional. Zippers work well and are easy to use. And of course, it's very light, which is the primary reason I got it. I'd definitely buy again.

Heavenly
[This review was collected as part of a promotion.] This bag is definitely incredible. Its packability is superb and it’s lightweight. It’s very comfortable in temps well below its 45f rating (32F) with the addition of just a pair of good down booties and a down jacket. Ive used it for fastpacking in the high peaks of Colorado with a bivy.

Absolutely incredible
[This review was collected as part of a promotion.] This weighs nothing at all. It's so amazing. I feel lucky to have this. It's crazy warm and soft and cozy. If I could sleep in it every night I would. I'm amazed by how warm this is with it weighing nothing at all.

Super Light Yet Warm
[This review was collected as part of a promotion.] It's a super comfortable, durable, and warm sleeping bag. I was impressed since it is super lightweight and easy to carry, especially with the bag it comes in. I do wish it was more compact, depise it being super lightweight, I feel like it takes up a lot of space.

Light & small, but performs great
[This review was collected as part of a promotion.] I am so impressed how light this sleeping bag is, but still keeps me warm! Compresses down without a problem - perfect companion for a backpacker/hiker. Love the attention to detail with the zipper - did not have any issues with snagging. Camped on a lake island with temps getting in the low 40s and still was comfortably warm. Material is easy to clean and shake out. 10/10 recommend.
