Sun protection doesn't have to mean long sleeves all day! These Coolibar sun sleeves give you the ultimate convenience - wear them with any short-sleeve shirt when you're in the sun, then easily pull them off when you move to shade. The UPF 50+ rating blocks 98% of harmful UVA/UVB rays, giving your forearms serious protection without the bulk of traditional clothing. The ZnO SUNTECT fabric feels incredibly soft against your skin while being lightweight and breathable enough to stay comfortable even on hot days. They stretch with your movements but stay securely in place without feeling tight or restrictive. The open cuffs allow for easy on/off and better airflow. Available in multiple sizes with bicep openings from 5-6 inches and lengths from 17-18 inches depending on size. Perfect for everyday activities like walking the dog, gardening, yard work, golf, or just hanging out outdoors. They're machine washable and hold up well to regular use. Just remember these aren't designed for swimming - they're not chlorine or salt water resistant. The snug fit feels secure without cutting off circulation, and the fabric wicks moisture to keep you cool and dry. Whether you're sensitive to sun exposure or just want to be smart about skin protection, these sleeves are a game-changer for enjoying outdoor activities safely. Much easier than constantly reapplying sunscreen to your arms!
