There is no perfect wader to match every season and application but a quality pair of breathable waders comes pretty darn close. Breathable waders are lightweight and extremely comfortable. They?re constructed with membranes that lock out exterior moisture while allowing your perspiration vapor to escape at the same time. This means that you?ll stay dry all day whether you?re fishing leisurely or covering water quickly in warm weather. In the spring and summer, they can be worn with a pair of light shorts and a tee shirt. When fall and winter roll around, just slip into a quality base layer, some fleece wader pants, and appropriate top layers and you can handle surprisingly cold temperatures. Breathable waders are definitely the most versatile and comfortable of all the material types. Knee and seat regions are generally reinforced with extra layers to provide additional strength and durability in these high stress/wear areas.
