Spark Down Sleeping Bag

This is a great little bag that I actually use for all sorts of warm weather things, including when I’m traveling in a hotel room and I don’t like the sheets! It also packs into something the size of a Nalgene bottle, which is incredible to me. Great product.

Super Warm And Light

This thing is so cozy and I loved the footroom and fabric that repels moist

I Love This Product!

Truly a best in class sleeping bag for backpacking, I love it! Retains body heat well, great product!

Took The Spark Down To

Took the Spark Down to the woods on a Canada trip- loved the light weight, compaction of the bag. Stayed warm throughout the night. Had some rain get in the tent, the bag dried out extremely quick. The bag is soft and comfortable, really like how it's not overly heavy and still retains it's loft. I need equipment that is light, durable, and quality. I don't want to be out in wild, miles from anything and be wet, cold, and miserable with bad gear. Very happy with the product!

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)!
