Q: What makes a fly fishing jacket different from a regular rain jacket?
A: Fly fishing jackets are specifically designed for anglers — built with waterproof, breathable materials and tailored cuts that allow freedom of movement while casting, they are often cut shorter so that you don’t get them wet while wading. They often feature gear-oriented details like high pockets, adjustable hoods, and D-rings for net or tool attachment.

Q: Are fly fishing jackets waterproof or water-resistant?
A: Most fly fishing jackets are fully waterproof, using advanced membranes like GORE-TEX or proprietary waterproof-breathable fabrics. Some lightweight models are water-resistant and ideal for wind protection or light rain.

Q: What types of outerwear do you sell for anglers?
A: Drift Outfitters carries waterproof wading jackets, insulated jackets, soft shells, and packable rain shells. Each piece is designed for performance on the water — whether you’re fishing through a storm, hiking into remote water, or layering for cold weather.

Q: Which fly fishing outerwear brands do you carry?
A: We carry premium brands like Simms, Patagonia, and Hooké. These brands are known for durable construction, weather protection, and comfort that performs season after season.

Q: How do I choose the right fly fishing jacket?
A: Consider your fishing conditions — a lightweight shell works best for summer rain, while insulated or waterproof wading jackets are ideal for cold or wet climates. Fit, breathability, and layering compatibility are key for comfort and performance.

Q: How should I care for my fly fishing jacket or outerwear?
A: Rinse off dirt and salt after each trip and wash occasionally with a technical fabric cleaner to maintain breathability. Reapply a DWR (durable water repellent) treatment as needed to restore water-shedding performance. Always follow brand-specific care instructions for best results.
