DESCRIPTION

Thanks to its highly breathable, water-resistant design, the 36-degree down Sea To Summit McII Sleeping Bag provides lofty, three-season warmth in a small, lightweight package. While compressed, this convertible mummy is the size of a small stove, but when unpacked, its 2D NanoShell and Nano DWR tech uses tiny water-resistant particles to prevent condensation and water vapor from accumulating in the down.
