Trek TkI -1C Ultralight Down Sleeping Bag

About the Sea to Summit Trek TkI - 1C

The Trek TkI sleeping bag delivers Sea to Summit's trademark performance with a water-resistant breathable shell fabric filled with 650+ down insulation for backpacking and camping.

The Trek Tk range is designed with a classic tapered rectangular shape and lightweight 30D nylon shell to deliver a low bulk sleeping bag with a compact design and ultralight weight of just 920g. This is ideal for those looking for a sleeping bag for fast-moving, warmer weather adventures from trekking and wild camping to backpacking.

The versatile design features a foot opening zip at the foot for temperature regulation and full-length side zip, to allow it to be used as a quilt in warmer conditions. Also features vertical chest baffles to prevent down migration and cold spots; oversized zip draft tube with anti-snag materials, and a 3D hood draws in tight when needed.

Ultra-Dry Down® 650+ insulation gives you a highly compressible premium goose down with water-repellent treatment that protects from both external moisture and internal condensation. This helps retain over 60% more loft and absorb 30% less moisture when compared with untreated down and continues to insulate even in damp conditions.
