Pearl Izumi Men's Merino Thermal Long Sleeve Bike Baselayer

This is Pearl Izumi's heaviest base layer, at 250g/m2. It combines their 18.5-micron responsibly sourced Merino and recycled polyester technical fibers in a remarkable construction that positions the polyester next to your skin for maximum wicking while the wool faces out for superior insulation. With its long sleeves it is the ideal garment to layer beneath one of Pearl Izumi's AmFIB® jackets. Thumb loops keep the sleeves in place as you pull on your jersey.
