Find Your Size
European sizes are based on your child’s height in centimeters. Because kids of the same age can be different sizes, height is the best guide for fit.
Enter your child’s height in inches, and we’ll show the closest CM size range. This correlates to the first number in the size option. ie: 98 or 122. If CM sizing is not provided, simply choose the age provided.
💡 Tip: These are general guidelines. Always check specific brand size charts when possible, as sizing can vary between manufacturers.
Product Description
Cold-weather adventures often start with the layer closest to the skin. The Reima Lampo Kids' Seawool® Thermal Base Layer Set brings warmth, softness, and comfortable stretch together for outdoor school, snowy play, winter walks, and active days when kids need an easy foundation for layering.
The Lampo is made from an elastic Seawool® terry fabric containing recycled polyester and recycled Seawool® fibers made using recycled oyster shell powder. Reima uses these distinctive fibers to add warmth and softness, while a short, soft pile on the reverse creates a cozy feel. The smooth outer surface makes it easier to add additional clothing over the top as temperatures and activities change.
Soft, flat seams are designed for added comfort during movement, while the elastic material gives kids room to bend, climb, run, and explore. The pants have an elastic waist for a simple, comfortable fit. Together, the top and bottom create a versatile first layer for everyday winter routines and longer adventures outside.
Why Parents Love It
- Warm from the first layer: Seawool® fibers and a soft reverse pile create a cozy thermal layer for cold-weather adventures.
- Comfortable for active kids: Elastic fabric moves with kids as they run, climb, play, and explore.
- Easy to layer: A smooth outer surface helps additional layers slide comfortably over the base layer.
- Thoughtful seam construction: Soft, flat seams are designed to reduce rubbing and add comfort during active wear.
- Simple everyday fit: An elastic waist keeps the bottoms straightforward and comfortable for winter routines.
Built for Real Outdoor Use
The Lampo is designed to be the comfortable starting point of a winter layering system. Its soft reverse pile provides warmth next to the body, while the smooth outer surface works well underneath fleece, mid-layers, snowsuits, ski gear, and other cold-weather outerwear.
Because the material is elastic, kids can move naturally through active outdoor days without a stiff first layer getting in the way. From outdoor school mornings and ski days to sledding, snowy hikes, and everyday winter play, the Lampo gives families a versatile thermal layer that can adapt as the rest of the layering system changes.

For us, the right gear from ODSS supports what we believe most about childhood. When children are able to be outside every day, in all seasons, they become tenacious, confident, and develop an authentic relationship with the land.
