When temperatures drop, sometimes your regular inner layers just aren't cutting it. The solution? Kids' HEATTECH. Thin, light, and so warm, kids' HEATTECH is ideal for keeping those little ones warm all winter long.

For climates that are chilling but beat a freeze, regular kids' HEATTECH is the perfect choice. When it's really cold, HEATTECH extra warm is approximately 1.5 times warmer, meaning it's great for outdoor play, hiking, and other activities.

It's not just about tees and tops, too — kids' HEATTECH offers bottoms, which are great for layering under jeans or sweats when the cold sets in. Kids' HEATTECH provides the utmost in warming inner layers, and it's only available at UNIQLO.
