Insulated Vest FHM Mild DuPont Sorona Blue

Insulated Vest FHM Mild is a lightweight technical garment engineered with high-tech DuPont Sorona insulation for superior thermal regulation. Designed for high-output activities such as hiking, biking, climbing, and fishing, this synthetic mid-layer is more breathable than down and resists moisture absorption. The 100% nylon outer shell and lining house the Sustans bio-based fiber, which provides exceptional loft and warmth while utilizing 30-40% less energy during production than standard nylon. DuPont Sorona technology works by utilizing unique molecular structures that create a resilient, elastic fiber with high insulation-to-weight ratios. This bio-based insulator ensures the body remains warm and dry by maintaining its loft even in damp conditions, improving performance in cold weather environments.

Features

• High-tech insulation: DuPont Sorona Sustans bio-based fiber provides excellent loft and thermal retention.
• Moisture management: Synthetic fill is more breathable than down and won’t soak up moisture readily during activity.
• Secure storage: Features a chest pocket with zipper, two hand pockets with zippers, and an inner pocket for essentials.
• Wind protection: A specialized protection strip is positioned under the central zipper to block cold air drafts.
• Adjustable fit: Elastic edging on the armholes and an adjustable bottom part ensure a personalized, heat-trapping seal.
• Compact packing: Includes a dedicated cover for packing, making it easy to store in a backpack or luggage.

The Sustans insulation maintains its loft and warmth even as morning mist settles on the 100% nylon shell during a river valley crossing. Because the synthetic fibers do not soak up moisture as readily as down, the vest remains breathable while climbing steeper trail sections toward sandstone outcrops. When the temperature rises, the lightweight construction allows it to be packed into its own cover and stored without adding significant bulk to your gear kit.

Technical Specifications

Fabric and Technology
