Layering is the key to stay warm and dry in cold water with breathable waders. Actually if you fish breathable waders you must use underwear that is made from synthetic materials or wool and definitely NOT a pair of sweatpants or similar..

Use a pair of thin, long underpants under our FLEECE BIBS and they will keep you warm in temperatures below 10 degrees, it’s important for your health. These bibs are made in 500 gram double side non-pilling fleece in top quality. They have practical features like adjustable suspenders, two-way zipper and a Lycra stirrup on the foot to prevent the leg to slip-up when you enter and use the waders. The high back of the pant provides added insulation and comfort. It also prevents any kind of gap between underpants and shirts to occur. This is a thick pant for use during low- to medium hard activity, designed to use in combination with breathable waders.
