Product Reviews
Rated 5 out of 5 by from This bag is amazing. I've [This review was collected as part of a promotion.] This bag is amazing. I've used it once so far, and I love it. Very happy with how it compresses when I pack it, and it fluffs out great. Got it for bikepacking, and I love it.

Rated 5 out of 5 by from Super Light, packs small, keeps warm! [This review was collected as part of a promotion.] Amazing sleeping bag, keeps really really warm and packs super small thanks to the compression sack. As expected from a super super light product, the shell is fragile and gotta be careful not to rip it. I used it on a bikepacking and then a backpacking trip through Patagonia and never really worried about the cold.

Rated 3 out of 5 by from I really want to love it but I feel so cramped Pros: the bag is ultralight and a dream to pack and carry Cons: I don’t have wide shoulders but I feel so cramped in this bag. Every trip sometime in the middle of the night, I seriously consider buying a new bag when I return home but this was too expensive to give up and it’s just so incredibly light to backpack (and when you are carrying your gear plus your kids it matters). The half zip is also kind of annoying but I’d deal if I could just fit my upper body in better. and for reference, I’m not a big girl, I’m not petite but I should fit a standard size bag.

Rated 5 out of 5 by from Awesome Bag [This review was collected as part of a promotion.] Awesome bag. Used it on a backpacking trip into Koai’e Canyon on the island of Kaua’i.

Rated 5 out of 5 by from Great Bag-Packs Small [This review was collected as part of a promotion.] Read other review recommending setting up sleep system early to allow bag to loft and shake several times to make sure down is distributed evenly. I would agree with that advise. Had issue with Ether Light sleep pad not holding air/leaks/tears along the fabric of the mat, so hard to gauge temperature rating.

Rated 5 out of 5 by from This is probably one of [This review was collected as part of a promotion.] This is probably one of the lightest and warmest sleeping bag you will find. I’m sure there are other cheaper ones that are as warm but if you had to carry 2-3lbs and the bulk it normally comes in, then you’ll really appreciate how light and how compact this sleeping can be. The outer shell is extremely soft inside out. Just love it

Rated 5 out of 5 by from Light, Highly Packable, Warm [This review was collected as part of a promotion.] The spark series bags have yet to disappoint! Note- there are a few compromises for the best performance, like a very light gauge zipper, 1/2 zip length, and a strong taper for the feet. If you are extremely claustrophobic and like to sleep like a starfish you may want a heavier bag for comfort- but that one small issue aside this bag is incredible! I find myself bringing it along on long backcountry day missions for a little extra insurance should I need to spend an unplanned night out! It is so light and small it fits in any kit, even ultralight bikepacking gear. Would recommend this bag to anyone!

Rated 5 out of 5 by from First trip with this bag [This review was collected as part of a promotion.] First trip with this bag was an 8 day elk hunt with temps frequently in the low 20’s at night. Used the bag in conjunction with the ether lite insulated pad directly on the ground in a tarp tent as well as a couple nights in a hammock. The bag was comfortable and warm except for my feet getting cold a couple nights which was easily remedied by tossing my base layers in the foot area at night. Packed down small in my rucksack and was everything I had hoped for when looking for a higher quality bag.
