CONTROL YOUR MICROCLIMATE
Wearing waders creates a microclimate around your body. Being active increases the heat and humidity that is trapped by your clothing. 37.5 fabrics use naturally derived particles to dramatically increase surface area and make clothing far more breathable. The material is special, responding to your level of activity so that the hotter you get, the harder the material works to cool your body. It never washes out and will last for the lifetime of the wader.
