Bontrager's B3 Hooded Long Sleeve Baselayer is a midweight undershirt for cool to cold conditions. The thermal knit material retains warmth, breathes well and facilitates moisture transfer better than a jersey alone. With a longer torso so you can tuck it into your tights, this sleek baselayer also sports thumb holes in the sleeves that make it easier to put on additional layers and gloves. The close fit, 4-way stretch and smooth exterior give you perfect layering without bulk. And, the low-profile hood easily fits under a helmet and gives you coverage all the way up to your chin and the side of your face.
