Breakdown For those early season scouting and hunting trips, the Marmot Hydrogen is your go-to bag. The Hydrogen utilizes 800+ fill power goose down. Additionally, a down defender treatment improves water resistance in wet conditions. An anatomically designed foot box with wrap-around construction increases warmth for your feet. The main access zipper has an anti-snag slider making it that much easier to get into bed on a chilly night. The pack size is impressive, packing down to a mere 4.6L size. The Hydrogen is lofty, sleeps warm, is extremely lightweight, and takes up almost no space in your pack. It’s a perfect addition to your early season kit.
