The 32 Degrees Kids' Heat Set is a thermal base layer clothing set designed for active children. This comfortable set includes a long sleeve shirt and matching leggings that provide warmth and flexibility for various activities.

The thermal base layers are made from a soft fabric blend of 37% acrylic, 34% polyester, 25% rayon, and 4% spandex. This material composition ensures the garments are lightweight for easy layering while effectively retaining body heat and wicking moisture away from the skin. The stretchy fabric allows for full range of motion during physical activities.

These versatile base layers can be worn under clothing for outdoor adventures like hiking and climbing on cooler days, as an extra layer under pajamas for camping trips, or simply as comfortable everyday wear. The garments are designed to withstand regular wear and maintain their shape and softness through multiple washes. Available in multiple color options including black and navy, with various sizes ranging from extra small (4/5) to extra large (16/18). The sizing tends to run slightly generous.
