Frequently Asked Questions

The sizing maps to standard youth sizes (Small=8, Medium=10-12, Large=14-16, XL=18-20). For use as a base layer under a heavier shell or ski jacket, sizing up one size gives comfortable room to layer without restricting movement. For standalone wear, true-to-size fits well.
Polyester thermal knit retains its shape better than cotton through multiple wash cycles and resists shrinkage. Machine washing on cold and tumble drying on low preserves the debossed texture and keeps the fabric from pilling faster than expected. Avoid high-heat drying, which can flatten the thermal texture over time.
Yes — the collar is tagless, which removes the most common source of neck irritation for kids during extended wear. The ribbed crew neck provides structure without being constrictive, making it suitable for school, sports, or layering under outerwear.
Youth size Large (14-16) is generally appropriate for boys around 10-13 years old depending on build, corresponding to a chest measurement of roughly 28-30 inches. Spyder's youth sizing aligns with standard US youth apparel sizing, so existing measurements should translate reliably.
