UPF 35 SUN PROTECTION BASE LAYERS
Our UPF 35 Base Layers were made for long days in the sun — whether that’s sand, surf, or dust. They’re cool, ultra-breathable, and insanely soft, built from a premium nylon-spandex mesh that protects your littlest loved one but feels like air. One comes in full checker, the other in bold black-and-white stripes with a black hood — both made to layer under any of your favorite LT tees, turning summer staples into reasonless essentials that actually do something.
Machine wash with other like colors. Hang dry or machine dry on low. Expect 1-2cm of shrinkage on first wash/dry but no shrinkage after that. Sizing is based on age range in the 50th percentile. If between sizes, size up! DO NOT TUMBLE DRY ON HOT/WARM.
