With our waterproof, breathable Kids' Kollen Lab HT Pants, hiking and playing outside is fun even in windy, rainy weather. We constructed these pants with our Helly Tech® Performance technology so kids stay dry and comfortable in wet conditions. These durable pants feature reinforced fabric on the seat, knees, and bottom hem for extra durability. They also have an adjustable waist and extendable legs so growing kids can wear them for longer.
