The Pearl Izumi Transfer Lite Short Sleeve Base Layer is meant to fit like a second skin. That's just the way you want it snug so it pulls sweat directly off your torso and prevents you from having that clammy sensation from a damp clinging jersey. It also helps to negate the potential of getting chilled as you finish your ride after the heat of the day has passed.The Transfer Lite base layer does even more work than what's possible with the standard P. R. O Transfer synthetic fabric because it's made with an additive called Minerale. It has fifteen times the surface area of normal polyester yarns to help it wick sweat directly from your skin like a sponge. The beauty is that it doesn't absorb moisture, rather it spreads it out on the surface of the fabric for maximum evaporation leaving you feeling dry and comfortable regardless of the outside temperature. As a result, it dries 50% faster than standard polyester fabric.Minerale also prevents the growth of bacteria that can cause the familiar synthetic aroma to take hold of your cycling clothing. This stink resistance is due to the inclusion of minerals in the porous fibers of the yarns. The Pearl Izumi Transfer Lite Short Sleeve Base Layer is available in five sizes, from Small, to XX Large, and in the colors Black, and White.
