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.

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.

So comfy and warm
[This review was collected as part of a promotion.] This is definitely an investment in a quality sleeping bag for camping. The down material keeps you warm and snugged in temperatures that can drop overnight. It can me packed up nicely, lightweight and does not take up much space. It is very roomy, I am petite, female and 160 lbs, it zips up easily and does not snag. It is like cocoon shaped and air does not good to keep you warm. I amazed by the quality and craftsmanship. It is extremely soft and so comfortable. You have to remember the key is quality, comfort, comfort and warmth. In addition to being light weight so you can transport easily.

Most Luxurious, Comfortable, Lightweight Material I Have Ever Felt!
[This review was collected as part of a promotion.] As an avid hiker/backpacker, I have been wanting a sleeping bag that is super light to not weigh me down and small enough to not add too much bulk on my back. I have only heard good things from the Sea to Summit brand, so I was excited to try the 30-degree Spark Down Sleeping Bag. It came with a storage bag, a smaller compression bag, a clip, and a down certification paper with tons of interesting information about the down filling. It's amazing how compressed this sleeping bag can get, and it is so super lightweight! It didn't feel like any added weight at all when attached to my backpack! It zips down about halfway, so I had plenty of room to get in it. The zipper is smooth and seems very high quality. It is a mummy style bag, so it's meant to be snug in the footboard area. However, I had plenty of room for my feet and legs to move around. I was afraid it would feel too restrictive for my liking, but that wasn't the case at all. I could move my legs to be about shoulder width apart. The hood cinches, which helps with warmth as well. For context, I am a 5 ft 5 in female that weighs 135 pounds, so I can see this working for a variety of people given how much extra room I had. As far as comfort, I can't even describe how pleasant this bag feels. My words when I first got in was, "Wow, this feels like liquid gold surrounding my body!" That's the only words that came to mind, but it's the best feeling material I have ever felt! It's truly amazing and makes me want to use it in my bed every night! Even though it's extremely soft, it also seems like a high-quality shell that will withstand several seasons of camping. As far as warmth, I took it outside on a cold night, about 35 degrees, just to test it out. I was still warm after quite a few minutes, so I think the 30-degree rating is spot on. Overall, I am extremely happy with this sleeping bag and totally recommend it to anyone looking to prioritize comfort, warmth, and lightweight material!

Fantastic and light weight!
[This review was collected as part of a promotion.] Wow! Blown away by how light this is! It folds down super small if you use the compression bag it comes with or the regular uncompressed back for normal storage. It’s a decent roomy size for a mummy bag that fit both myself and husband just fine without feeling too tight. The no snag zipper is a nice bonus feature along with the ability to synch in the hood/top part. The outer material is thin but has a coating on it that makes it more durable than expected. It warmed up quickly with body heat and I have no concerns about being cold within the approved temperature range. Would recommend and excited to get more use of this as camping season picks back up!
