Castelli UPF 50 Arm Sleeves

When the high-altitude sun sharpens its glare, or the open road stretches endlessly under a cloudless sky, Castelli UPF 50 Arm Sleeves become your unseen ally. Crafted from a remarkably light, quick-drying fabric, they actively block 98% of harmful UV rays, achieving a true UPF 50 rating without adding bulk. The soft, almost imperceptible material contours fluidly, making it easy to forget they're even there, while micro-perforations ensure constant airflow for exceptional breathability. Reliable silicone grippers hold them firmly in place at the bicep, promising a no-slip performance even through dynamic motion.
