Hot Chillys Youth MTF Originals Crewneck Midweight Base Layer - UPF 30

Warmth, stretch, and everyday comfort in one base layer

Designed for kids and teens who keep an active pace, the Hot Chillys Youth MTF Originals Crewneck is a midweight long-sleeve base layer. It sits close to the skin with a soft touch, offering warmth without bulk while allowing for easy layering under outerwear. The fabric is engineered for breathability and moisture management, helping comfort stay ahead of sweat during after-school adventures, weekend hikes, or chilly commutes.

Why it feels different
