If you're counting grams, but still count on a great night's sleep, the Spark may be the right bag for you. Filled with RDS-certified 850+ fillpower goose down treated with a non-PFC Ultra-Dry Down treatment, the Spark is constructed with a technical hood and zipper draft tube to retain warmth. Comfort comes from a super-breathable 10 denier liner fabric, while a 10D shell with a non-PFC DWR plus a highly water repellent hood and footbox fabric shed wind and condensation. The full-length zipper model can be zipped to an equivalent Women's Spark for comfort that couples can share.

  • RDS-certified, 850+ fillpower goose down with a non-PFC Ultra-Dry Down treatment for maximum thermal performance

  • YKK #5 zippers with zipper plow provide reliable, snag-free operation

Scary Light

[This review was collected as part of a promotion.] I get cold very easy, even in warmer temps. I was so nervous to try out this bag, because it feels super lightweight and airy. I thought it couldn’t possibly be warm enough. I got the chance to test it out recently, and even brought an extra bag just in case I needed to double up. No sir! I slept snug as a bug the entire trip. Not only is it cozy and lightweight, it also packs down small. Perfect for fitting in a suitcase, backpacking, or even alpine.

Great 👍🏾

[This review was collected as part of a promotion.] Slept great on the air pad and tucked nicely in the spark. Temps down to 30 degrees and woke up with frost on the ground. The 15 degree sleeping bag did great.

Spark Down Sleeping Bag

[This review was collected as part of a promotion.] 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
