The big fish don't live in places that are convenient to get to, which is why Simms designed the Men's Vapor Felt Boot. With a hiking boot-inspired design, this wader is lightweight, comfortable, and capable of getting you to those spots on the river that most people don't even know about. That's not to say that Simms didn't consider toughness, however, because it fitted the Vapor with a rugged synthetic leather, textile, and scratch rubber upper capable of putting up with abuse. It also equipped this baby with a comfortable, anatomical top collar and plush neoprene lining in the places where it counts the most. The VaporTread platform adds comfort, and the felt outsole keeps you upright on slick-as-snot river rocks.
