Reima outerwear is designed to allow room for growth and therefore includes approximately 2 3/8" (6 cm) of extra space, which means our sizes may run large. However, it is still recommended to buy the size that corresponds to your child's age.
Please note that to use the size chart, you must take your child's body measurements, not a garment's measurements.

The Reima Ilmassa kids' shorts keep active children cool during intense summer adventures across toddler and youth sizes. Reima crafts these high-performance athletic shorts from 91% recycled polyester and 9% elastane, featuring an innovative Xylitol Cool surface treatment, an ultraviolet protection factor of UPF 40+, a 4-way stretch fabric build, and a customizable drawstring waist. High temperatures stop ruining gym class or playground running. Soft technical materials continuously pull internal humidity away from hot skin. Children sprint, leap, and climb in total comfort without restrictive fabric holding them back.
Why Ilmassa Shorts From Reima Master Hot Weather Play
Sweltering heat forces kids indoors early. Heavy cotton shorts trap body heat and absorb sweat, causing uncomfortable chafing during long afternoons at the park. These technical Ilmassa shorts by Reima active bottoms solve summer overheating through plant-based xylitol finish technology that lowers skin temperature by up to three degrees Celsius. Moisture triggers the cooling reaction instantly during high-energy games.
Durability remains essential for daily outdoor use. Tough synthetic weaves resist tearing during slide rides, turf sports, and backyard games. The four-way elastic stretch material expands in every direction to allow complete movement. Handy side pockets hold small treasures safely, while the adjustable elastic waistband prevents annoying slippage during active play.
