Perfect Summer Bag

Had this bag with me on an 8-day bikepacking trip round the Pacific Northwest. Light, packs small, and functions as you’d expect (no zipper snags)!

Overall Great Warmth/weight Ratio

Over three months I've taken this bag camping on the Alaska Marine Highway (ferry) and a couple 1-3 nighters in the Cascades. It's not the warmest bag you'll find, and on a cold night in the mountains (in a 3-season tent), I was a little bit cold -- though not uncomfortably so. However, it's a great compromise on warmth/weight -- and especially warmth/volume. It packs up so small, best part. The half zip is a little annoying, but I understand the compromise.

Amazing bag super compact and light and met all temp expectations

Spark Bag

Do not like 3/4 zipper. Makes bag difficult to get in out. Do appreciate the lightness of the bag.

Spark Down Sleeping Bag

I plurchased this for a fast thru hike on the Superior Hiking Trail. Nights got down to 40 degrees. I-was a little worried about the chill and the bag rating since I'm a t-shirt underwear and sometimes socks guy. But this was perfect. Finally a bag true to its rating. Yes my tent was small and my pad reflects heat as well. but the bag was warm and comfortable and packs down sooo crazy tiny.
