Powered by Lavalan® Sport insulation, this vest brings the natural benefits of wool to technical outerwear—providing reliable warmth, moisture management, and odor resistance, even in damp conditions.

Practical features include YKK conceal-zippered chest and hand pockets, plus an interior mesh dump pocket that doubles as a stow pocket, making this vest highly packable for extended trips. An adjustable hem ensures a secure fit that keeps warmth close.

Q: Why is layering important for fly fishing?
A: Layering helps you stay comfortable and adaptable in changing weather conditions. By combining moisture-wicking base layers, insulating mid-layers, and protective outer layers, you can regulate temperature, stay dry, and fish comfortably in any season — from chilly steelhead mornings to cool alpine streams.

Q: What types of layering clothing do you sell?
A: Drift Outfitters carries a complete range of thermal and layering pieces including base layers, fleece, insulated jackets, and soft shells. These garments are designed to keep you warm and dry without restricting movement, making them perfect for fishing and outdoor adventures year-round.

Q: What materials are best for thermal and layering clothing?
A: The best layering materials include merino wool, polyester blends, and technical fleece. These fabrics wick moisture, dry quickly, and provide warmth even when wet — unlike cotton, which retains water and can cause heat loss in cold conditions.

Q: Which thermal clothing brands do you carry?
A: Drift Outfitters carries trusted performance brands like Simms, Patagonia, and Hooké. These brands are known for their high-quality technical fabrics, comfort, and durability in demanding fishing and outdoor environments.

Q: How do I layer clothing for cold-weather fishing?
A: Start with a moisture-wicking base layer, add an insulating fleece or mid-layer, and top it off with a waterproof or windproof shell. Proper layering traps heat and manages moisture, keeping you warm without overheating.

Q: How should I care for my thermal and layering clothing?
A: Wash according to manufacturer directions. Air-dry or tumble on low heat to maintain performance and prevent shrinkage. Always follow brand-specific care labels for best results.
