Frequently Asked Questions

AI
Cotton is ideal for low-activity levels and breathability, while synthetic moisture-wicking fabrics are better for skiing or active play in the cold to prevent dampness and chills.
Wash in cold water and avoid high-heat drying. For synthetic blends, air drying or low-heat settings are most effective for maintaining the elasticity and fit.
Prioritize tagless designs to prevent irritation and soft, stretchy fabrics that provide a consistent fit as children grow.
