Our best-selling Young Rider base layer now has short sleeves for summer! Whether your young rider is running, riding or walking the dog, the 360° stretch, anti-microbial, sweat-wicking fabric will help regulate their body temperature to keep them cool and dry while they sweat. The silky fabric features UV 50+ protection to protect them as a stand-alone garment on sunny days. What's more, ultra-soft seams and flat stitching reduce chafing and minimize bulk when worn under fleeces, jackets or vests. Choose from a variety of attractive colors and coordinate your look with our matching garments and accessories.
