5-Season Extreme Sleeping Bag

SKU: AS-SB-22

Standard bags just do not cut it when the temperature drops below freezing. This 5-season bag is built specifically for extreme winter weather. It uses a twin-shell design with a windproof micro-fleece outer and a thick fleece inner lining. Paired with smooth, flat crash zips, it keeps you toasty warm but never slows you down when you get a sudden run in the middle of the night.

Direct from audited factories: We personally check the thermal testing reports to guarantee true weather ratings.

User Scenarios

You are out on a winter reservoir with frost covering the ground. Inside this bag, the thick fleece wraps you up and you feel right at home. When the bite alarm screams at 2 AM, one quick push opens the crash zips, letting you out of the bivvy in two seconds flat to hit the rod.

Sourcing Partner Case Study

A British tackle brand was dealing with heavy customer returns because their previous winter bags were poorly insulated. We stepped in, cut out the middlemen, and managed their custom 5-season sleeping bag sourcing closely. We kept a strict eye on the fleece weight at the factory level. By shipping these alongside proven products from a wholesale carp fishing bivvy China manufacturer, we helped them rebuild their winter reputation with highly reliable, cost-effective gear.
