TORAY

Toray® fabric technology was developed specifically for fishing waders. The QuadraLam™ fabric featured in the Freestone® wader is a heavy-duty engineered fabric with a micro-porous waterproof coating that utilizes 2-layer coated fabric, a single membrane layer and a tricot backer to offer improved durability.

 PERTEX® ENDURANCE

Pertex® Endurance is designed to provide significant weather protection for insulated garments in extreme conditions. It incorporates an ultra-thin air permeable coating that is highly breathable, water and wind resistant. This layer protects the insulation from the elements, maintaining loft and retaining warmth.

 PRIMALOFT® GOLD

Primaloft® Gold insulation maintains 90% of its warmth when wet and provides the highest warmth to weight ratio of any synthetic insulation available.
