Product Information
Guideline's Alta NGx Sonic Jacket is a waterproof, breathable wading jacket for fly anglers. Its articulated shoulders and elbows allow unrestricted movement when casting.
High-frequency ultrasonic welding helps it remain flexible and waterproof. A fleece-lined high collar, YKK Aquaguard front zip and DuoDrag neoprene cuffs are designed to keep cold and water out.
Two high chest pockets hold large fly boxes and include organisers for tippets and spools. Size L weighs 754g, and the shell is 3-layer 100% Nylon Taslan fabric.
