Helsport Polar Spitsbergen Dual -30

Helsport Polar Spitsbergen Dual‪ -30 is a twin-layer winter sleeping bag built for demanding deep-winter trips, combining a down inner bag with a synthetic outer bag for reliable warmth in harsh, humid conditions. Designed with input from polar expedition ambassadors, it suits polar-style expeditions as well as remote winter overnights in the Nordic backcountry. The updated inner bag uses high fill power goose down for higher loft, while the outer bag is made to better handle moisture when conditions turn wet and cold. Practical details like arm openings and a center Vislon zipper help make camp routines smoother on long winter nights.

• Twin-bag construction pairs a high-loft down inner bag with a synthetic outer bag for efficient insulation in extreme cold
• Updated inner bag with 900+ fill power goose down for increased warmth at a given fill weight
• Outer bag uses synthetic insulation to keep thermal performance more consistent in damp conditions
• Updated outer fabrics with waterproofness 1000 mm to better resist humidity and melting snow contact
• Center Vislon zipper is easy to locate and operate and is designed not to freeze up
• Arm openings on the inner bag allow tasks to be done without fully leaving the warmth
• Hood connectors help secure the inner bag to the outer bag so the two layers stay aligned
• Recycled shell and liner fabrics with fluorocarbon free DWR finish for a more responsible material choice
• Rds-certified grey goose down with 90/10 down-feather blend and fill power 900+ for traceable insulation performance
• Comes with a storage bag for packing and keeping the system organized
