- Viscose or rayon: Enhances softness and comfort when added to fabric blends.
Together, these materials help kids thermals remain comfortable, flexible, and practical for daily use.

-
Are kids base layers only for winter use?
- No, kids base layers can be worn year-round. Lightweight kids thermals work well in cooler summer weather or as a moisture-wicking layer during outdoor play.
-
Do kids thermals help keep children dry?
- Yes, kids base layers are designed to move moisture away from the skin. This helps reduce dampness and keeps children comfortable during and after activity.
-
Can kids base layers be worn on their own?
- They can be worn alone during mild weather or indoor activities. In colder conditions, they work best as part of a layered outfit.
-
Are kids base layers comfortable for all-day wear?
- Most kids thermals are made with soft, stretchy fabrics that feel comfortable against the skin. Flat seams and flexible materials help prevent irritation during long wear.
