"As a gear nerd and a skier I know that just about everything on the market these days that is breathable and waterproof works pretty darn well. The materials used in the Sonic-Pro waders are no different. Thus far I've tested them in conditions ranging from the low teens to hiking through warms conditions. In the cold with proper layering I was perfectly warm, while in the warm weather they were as comfy as any pair of high end waders I've ever owned."
