The First Skin serves as a base layer under waders when long-lasting thermal comfort is essential. Worn on its own, it reduces direct contact between the waders and the skin and provides a more comfortable layer in temperate conditions. In cold weather, it can be paired with an insulating midlayer. Its bamboo and polyester construction promotes moisture wicking and helps regulate temperature. Bamboo fibers also provide natural odor-resistant properties, which are useful on long outings or fishing trips.
