Frequently Asked Questions

AI
Look for polyester blends or cotton mixes that offer moisture-wicking properties. These materials keep your child dry during active play and provide consistent warmth without the bulk of heavy wool, making them ideal for layering under school uniforms or sports gear.
Thermal base layers should fit snugly against the skin to trap heat effectively but not restrict movement. Avoid overly tight fits that cause discomfort or loose fits that create cold spots. Check size charts carefully, as brands often vary in sizing for children's clothing.
Most sets in this category, including thermal layers and tracksuits, are designed for machine washing. However, always check the care label. Washing on a gentle cycle with cold water and air drying helps preserve the elasticity of the fabric and prevents shrinking or pilling over time.
