Sidewinder 20 Down Sleeping Bag

With cool Southeast shoulder-season nights in mind, the Sidewinder 20 is our go-to 20°F down bag for backpackers and hunters. Its 650-fill DownTek down repels moisture, so it holds loft in humid air and condensation-heavy tents, while three sizes keep dead space down and warmth up.

• 20°F rating covers Appalachian fall hunts, spring backpacking trips, and early-winter camps
• 650-fill DownTek down is water-repellent, so it keeps loft in humid air and condensation-heavy tents better than untreated down
• Responsibly sourced down (RDS) gives you a lightweight bag that compresses small in your pack
• Available in Small, Regular, and Long, so you get a snug fit that traps heat without wasted space
• Chinois Green, Mercury, and Evening Primrose colorway blends into the woods and works as a backcountry staple
