evo.com | Reima Long Underwear Sets > The Reima Lani Thermal Base Layer Set solves the problem of cotton base layers that turn clammy and cold the moment kids start moving. Thermolite fabric actively pulls moisture away from skin, so whether they're building epic snow forts or tackling black diamond runs, kids stay dry and comfortable instead of getting that soggy, chilled feeling. Flat seams eliminate chafing during all-day adventures, while strategic stretch panels help them move without getting all bunched up. 53% Polyester / 43% Polyester Thermolite(R) / 4% Polyester SORONA(R) Elastic Waist Regular Fit Soft, Flat Seams for Extra Comfort | Kid's Reima Lani Thermal Base Layer Set 2026 - 6-7 Blue | Cotton/Polyester
