Customer Reviews

The Reima Vauhdikas kids' cooling t-shirt features a high-performance recycled polyester blend jersey, UPF 40+ sun protection, and Xylitol Cool finishing technology designed to lower skin temperature during active play. Active kids need gear that keeps up with non-stop movement while managing heat buildup during hot summer afternoons. Built specifically for sports, playground runs, and gym class, this active top delivers moisture-wicking power and total freedom of movement.

Cooling Technology of Reima Vauhdikas

Playing hard in the heat usually means dealing with sticky, sweaty shirts. The Reima Vauhdikas active tee solves this problem using a specialized plant-based finish. This innovative treatment actively lowers the skin's surface temperature as soon as physical effort begins and moisture contacts the fabric. The quick-drying jersey structure draws sweat straight away from the body, pushing it to the exterior surface where it evaporates instantly. Your child stays fresh, dry, and focused on having fun instead of overheating.

Built for Maximum Flexibility and Sun Safety

Kids rarely sit still, so their summer wardrobe must handle dynamic movement. The four-way stretch fabric construction allows complete range of motion without pulling, tearing, or restricting arm movements during climbs and sprints. Built-in ultraviolet protection factor 40+ guards covered skin against harsh rays, allowing longer outdoor adventures without worrying about unexpected sunburns. Lightweight jersey knit provides a soft feel directly against sensitive skin while standing up to rough daily wear.
