Frequently Asked Questions
How many pieces are included in this set?
The set includes 4 pieces — two thermal tops and two thermal pants — giving you two complete base layer outfits for back-to-back wear days or easy laundry rotation.
What type of lining does this base layer have?
Each piece features a soft brushed-back fleece lining on the interior that traps body heat while remaining comfortable against the skin.
Is this set suitable for wearing under ski gear?
Yes, the slim, snug fit and stretchy fabric are specifically designed for layering under ski pants, snow jackets, and other winter outerwear without adding bulk.
How does the flat lock stitching benefit my child?
Flat lock stitching lies smooth against the skin rather than creating raised seams, which reduces chafing and irritation during active movement — important for kids who are skiing, playing, or moving throughout the day.
Can these thermals be machine washed?
Yes, the set is machine washable for easy care after active outdoor use.
