Sleeping bags with GORE® WINDSTOPPER® shell fabrics are built for the most demanding cold-weather and expedition environments. These bags are designed for prolonged exposure to wind, moisture, and extreme cold—where keeping insulation dry is essential for safety, warmth, and performance.

GORE® WINDSTOPPER® shells use a lightweight, two-layer laminated construction with a durable 30-denier face fabric, providing a strong barrier against wind and external moisture while remaining breathable enough for extended overnight use. This added durability makes these bags especially well suited for long expeditions, repeated use in harsh environments, and situations where abrasion resistance and weather protection matter as much as warmth.

All of our Expedition Series sleeping bags feature GORE® WINDSTOPPER® shell fabrics, delivering dependable insulation protection in extreme cold and wet conditions. If your objectives involve sustained exposure to severe weather, high-altitude camps, or remote environments where reliability is critical, GORE® WINDSTOPPER® sleeping bags offer the highest level of protection in our lineup.
