The Bontrager family of baselayers: B1, B2, and B3. Three different fabric designs. Three different fabrics weights. All moisture-wicking, quick-drying, and featuring 4-way stretch comfort. Each tailored for specific thermal performance.
Stay cool with B1, Bontrager's lightest weight baselayer. Designed to be worn as a first layer in warm temperatures, B1's ultra-light waffle knit construction reduces fabric-to-skin contact, creating air pockets next to the skin that aid in evaporative cooling.
