The primary goal of this technical garment is to wick moisture away from your skin while providing minimal insulation for cool days when you're cycling at a high intensity and your outer layers are sufficiently warm. You might feel warm in the areas covered by bib tights around the waist and back, which is why we've selected a lightweight PrimaLoft® fabric to help regulate and even out your temperature. This technical garment performs best next to the skin. Both fabrics are highly stretchy, and it has a close, body-hugging fit. On truly cold days, we use it as a base layer under a technical Flanders Warm mid-layer or a thermal jersey. It's very effective at wicking sweat away from the skin.
