Description

Ultralight and super-compact with 850+ ULTRA-DRY Down

The Spark 40F is an ultralight down bag that packs down super-small for use as a liner or standalone summer bag. The Spark uses premium materials, including ULTRA-DRY Down 850+ Loft Loft, and no-frills design to provide cutting-edge performance for backpacking, bikepacking, and travel. Ultralight does not mean ultra-tight: The Spark sleeping bags are snug but still have adequate girth for the performance-oriented backcountry user.
