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-PFAS 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-PFAS DWR plus a highly water repellent hood and footbox fabric shed wind and condensation.

The full-length zipper models can be zipped to an equivalent Women's Spark for comfort that couples can share

Miles ★★★★★

Weighs next to nothing but the 850-fill down kept me cozy well past midnight with temps dipping to the mid-20s. The draft collar made a real difference when I rolled onto my side. Feels like a solid upgrade from my old three-season bag.

Julian ★★★★★

Took this out on a 20°F night and woke up totally cozy, the non-PFAS down treatment kept it dry through a bit of condensation in the tent. It packs down ridiculously small for how much warmth it holds, and the Like New condition honestly looked untouched.

Zoe P. ★★★★★

The 850-fill down is absurdly warm for the weight, and the non-PFAS treatment handled a damp night without clumping at all. I've already used it on three trips below freezing and slept through every single one.
