Polarmax Youth Active Stretch Bottom

The Youth Active Stretch Bottom provides a warm, flexible thermal base layer designed for active kids. Its stretchy fabric moves with your child, offering comfort and insulation during outdoor adventures or chilly days.

Built to keep up with active kids in the cold, the Youth Active Stretch Bottom combines four-way stretch with midweight warmth for unrestricted performance on the slopes or at play. Soft, comfort-knit fabric moves naturally with growing bodies, while Acclimate Dry+ hydrophobic yarns wick moisture away from the skin quickly to keep kids dry and comfortable through high-energy activity.

Flat-seam stitching throughout minimizes irritation against the skin while maintaining durability and stretch over time. Layers easily under snow pants without bulk or works on its own in brisk weather — ready for whatever the day brings.

Key features:

• Four-way stretch comfort-knit fabric
• Acclimate Dry+ hydrophobic moisture-wicking yarns
• Midweight warmth for layering or standalone wear
• Flat-seam construction for comfort and durability
• Ideal for skiing, outdoor play, and everyday cold-weather wear
