This is your glove for cold and/or wet conditions. The Japanese neoprene is some of the highest quality available & this is what makes it so stretchy comfortable & warm. The seams are constructed using the same technique as a wetsuit: the stitching is only on the outside while the inside is thermo welded to make it smooth & completely waterproof. While the waterproofness is an obvious benefit in the rain whats not so obvious is how good this glove is in the cold. It keeps your hands warm with the same function as a wetsuit for divers. It is completely non breathable so your hand sweats but that moisture is immediately warmed to body temperature & stays warm. We figure its better to have hands warm & wet than dry & cold or worse yet wet & cold!
