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.

Loved by Parents, Approved by Kids

"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."

A+ Mid-weight wool sweater

My daughter loves her new sweater! She is 8 and I purchased a 10 for her which is big and will fit for a couple of years but it isn’t overly big as it looks nice on her now with the sleeves cuffed. It also washes really well. I have not seen a significant amount of pilling at all on any of our hopu sweaters. These are great and I will be back for more!

amazing quality

these are so soft and warm but nice and trim. im putting 4 stars because the shipping took a month (not a pre order) and I ordered 6-12 months size for my 8 month old. so he lost a month in these beautiful (and expensive) clothes. hoping he can still get good use out of them. so far it's all I want him to wear cause it's so cozy.

This wool is so soft!

I bought the hopu for my son who is 5. I got. Size 6 and it fits great with room to grow for next year. He wore this to outdoor school and the cuffs were filthy but a quick brush off and it was good to go for another day! It has washed up nicely since then. The fit is gender neutral which is great since both of my kids will fit in the clothes. We love wool clothes and Nui seems great. We will be back for more.

Comfortable and warm

Got this to try for winter/ski season. I would say it's a nice base layer/mid layer. It's really warm even though it's thin/fitted. My picky/sensory sensitive kid likes it so that's a win. It looks good on, and I would say it's true to size. And really gender neutral as well.
