A sunshirt like no other. Beloved by riders everywhere, our Sunstopper baselayers deliver more than UPF protection. Innovated with cooling, moisture-wicking, and odor-fighting technologies, they're crafted from a soft fabric that keeps you looking tidy from sunup to sundown. We even added mesh at each underarm for maximum breathability without sacrificing the coverage you need on warm, sunny days.
