The Wear-All-Year Knit

A knit that lasts through seasons, play, and growth. Made from ultra-soft, breathable 100% merino wool, these rib-knit leggings have the perfect stretch to stay up, stay on, and never sag. Naturally temperature-regulating, they keep little legs warm in the cold and cool when it’s warm. Sized to grow with them, just roll the cuffs up and let them unfold as they do. Wear alone or as a cozy base layer—these leggings are made for everyday adventure.

EVERYDAY VERSATILITY

One pair, endless wear. The Merino Knit Leggings combine warmth with stretch, making them the perfect layer for any season. Snuggly enough for cool mornings, breathable enough for active afternoons—whether they’re exploring, relaxing, or on the move, these leggings keep up.

Good for Your Kids, Gentle on the Earth

Here’s the truth: Most kids' clothes are made from cheap synthetic fabrics that leak microplastics, trap sweat, and wear out fast. The Merino Knit Leggings? It’s natural, breathable, and built to last.

"Kids love them!"

"These leggings are long which means we were able to use them for a long time, you can easily fold the legs. They seem to be warm, provide enough room on the waist even for a chunky baby, and work great as a single layer on those cooler evenings/mornings."

A Winter Wardrobe Staple

"These are much thicker than other NUI leggings I've purchased before...and I'm glad for it! These are thick yet flexible for movement, so they will be just great for any sort of everyday activity.


With the thicker weave, I can see these leggings lasting a lot longer than the thinner NUI leggings we are used to. I hope these remain a staple on the website because I'd definitely purchase them every year!"

Long and cozy

"Definitely no need to size up with these! I bought both 12-18 and 6-12 for my now 11-month-old, who's bigger/taller than average, and I find even the smaller size can work its way down over her feet. They'll last a while, which is great, as they're soft and good for daytime and nighttime"

The best wool leggings I've found

"I have been buying these leggings in multiple colors each year for my now-three-year-old and we love them so much. I haven't found wool leggings anywhere else that I like nearly as much.


These are a nice thickness to really keep the child warm and because of this they can be worn with or without additional layers, depending on weather, of course. The ribbing gives a nice stretch and they return well to their shape even without washing."

Kids love them

I get these for thicker ski thermals, and they double as PJs, which works out great. They're really warm and cozy and cute! The knees do wear out after a while but my boys are hard in stuff! We just patch the knees and keep on wearing them.

I have been buying these leggings in multiple colors each year for my now-three-year-old and we love them so much. I haven't found wool leggings anywhere else that I like nearly as much. These are a nice thickness to really keep the child warm and because of this they can be worn with or without additional layers, depending on weather, of course. The ribbing gives a nice stretch and they return well to their shape even without washing. Of course, they are also easy to wash, which is key. The only downside is they usually sell out quickly and don't seem to be available most of the year. We love them with the matching tops.
