The sleeping bag has a 650-fill power RDS-Certified Duck Down insulation yet maintains a decidedly streamlined silhouette to prevent it from being too bulky to carry. The mummy-style sleeping bag has a neck baffle to further enhance warmth retention, while the Thermolock draft tube prioritizes warmth across the body.
The Coleman Peak1 Zero Degree Sleeping Bag is accented by a sleeve on the underside for placing a sleeping pad to keep the unit in place. The bag is rounded out with recycled 20D nylon for the shell, a 40D nylon for the liner to combat against moisture and more.
