Spark 15° review

2 days ago
[This review was collected as part of a promotion.] This is one of the best sleeping bags I’ve ever owned!! 10/10 would recommend. The down is always warm and the ultralight pack ability makes it a go to for any outdoor adventure.

Small but missing critical baffles to keep you wam

17 days ago
Thru hiker here who has done the PCT and many treks in Nepal. I purchased the 30 degree bag for my latest PCT hike but have been pretty disappointed. While the size is amazing when compressed the design is missing critical baffles that would stop the down from clumping and exposing your body to nothing but the elements. My bag is comfortable if the outside temp is 55 or better. Anything less and I get cold even in this 30 degree bag. See my photos for what normally happens -- the down shifts in the large baffles leaving nothing between your body and the elements. They need to have smaller baffles that keep the down in place and down't allow it to shift so much. (Down jackets went through this same evolution over the years but SeaToSummit passed on using this knowledge in this bag design. ). I love the company and they've got some excellent gear I use on every trip, but unfortunately this sleeping bag is not one of their best. When I set up camp I thoroughly fluff the bag to help it expand and at that time I work to ensure the down is universally filling each baffle. But during the night with a little tossing and turning the down easily shifts and so I'm left with what you see in the picture -- freezing shoulders or hips because the down shifted. Picture is from inside the bag looking out so you can see how large 12" x 12" spots with no down present create cold spots for my body. I'm 6'0, 160 lbs, and a back/side sleeper. Over 20 years of professional guide experience. I hope Sea To Summit. updates this bag as they're close to having a lightweight bag with great warmth but just missed the ball on this one.

Perfect for Bikepacking

a month ago
I've been really impressed with this sleeping bag. It's super compact and packs down small, making it a great choice for bikepacking where every bit of space matters. It replaced my old bulky sleeping bag and freed up a lot of room in my setup. My only suggestion would be to have the zipper run a little farther down the side. I like to kick a leg out while I sleep, and a longer zipper would make that much easier. Overall, it's lightweight, packs incredibly small, and has been a fantastic upgrade. I'd definitely recommend it to anyone looking for a compact sleeping bag for bikepacking or backpacking trips.

[This review was collected as part of a promotion.] I laughed when I saw the stuff bag for this sleeping bag. I thought it would not be possible to use it. I quickly got used to it and used the sleeping bag on a cross-country motorcycle camping trip. Pack size is as important on a motorcycle as weight is for a backpacker, so this worked out well. The sleeping bag was comfortable and perfect for the season.

Great bag just not the most durable as expected

[This review was collected as part of a promotion.] Great bag I used it in a backpacking trip at 9,000 feet in early June I stayed warm and comfortable all night the material is very lightweight so I can tell it would rip easily but otherwise happy with it.

Excellent bag and service

I work wildland fire and hunt in the off season. Not to toot my own horn but i get a good sleeping bag when I have one. Comfort and weight are on point. great toe box. I was showing my buddy how light the bag was and he dropped it on a buddy heater. Sea to Summit took care of the whole fix. Absolutely amazing. Simple bag that works as one would want.

The Spark performs

6 months ago
I just completed a 750 mile section of the Florida Trail in 10 weeks. I slept in the 30 degree Spark every night. Throughout the 10 weeks there were many nights below freezing with temperatures dipping to the mid 20s. The spark performed marvelously! I even slept without a pad and still was comfortable. I wore multiple layers to sleep only once and frequently used my Poncho as a vapor barrier to help insulate. Other hikers complained about being cold when I was cozy and warm. The only complaint I have about this bag is that with the short zipper it can be a struggle to get in and out of sometimes. But I will take the weight savings that come with that feature over a little wiggling. The dampness of Florida nights did not cause the bag to become wet and my fears of carrying a down bag in a humid environment were conquered. A wonderful product all around.

[This review was collected as part of a promotion.] I got this as a dual purpose bag. First, an ultra light / ultra compact summer bag. Second, to pair with a 25 degree quilt for winter camping. Tried it once in a fire lookout and was too warm (ditched the quilt). Going to put it through its paces over the next year!
