Alpinestars says its new Summer Tech Performance underwear forms an effective base layer, keeping you cool and comfortable under your suit during warm-weather riding. The underwear features a unique new tubular construction method to minimize the number of joints to the garment, allowing minimal seam stitching for increased comfort. Muscle-supporting compression fit helps support the rider’s muscles and reduces fatigue. Dryarn material keeps its size even after repeated washings and is 60 percent lighter than cotton. $39.95 and up.
