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 Hopu Top? It’s natural, breathable, and built to last.

"Another Staple Piece from NUI"

"I'm so glad to be able to shop NUI for quality winter wardrobe pieces that are unrivaled in quality and material. This top is generous in terms of thickness and I do not underestimate its ability to last through time and all the winter adventures. I only wish for more colors!"

“Favorite Winter Staple”

"My daughter LIVES in these all winter. They keep her so toasty warm that she almost never wears a jacket! They’re also easy to size up in for multiple seasons and kiddos - just cuff them!


These are fantastically durable and well worth the price. Can’t wait to receive my son’s first set!"

“Our family's winter staple”

"These Merino Wool sets have become a family staple every Winter. My family and I are avid skiiers, and can’t use anything else as a base layer other than these warm, high quality, aesthetically pleasing wool sets!


They double as pjs on cold winter nights, and also come camping with us. Thank you Nui Organics!"

“The best wool top to go with the best wool bottoms”

"We love the knit leggings and have been sizing up each year for a few years. We always buy 2-3 of the Hopu tops to go with our 2-3 pairs of the knit leggings, and that's the core of my child's winter wardrobe.


Both the Hopu tops and the knit leggings have held up really well, and we've been able to pass them on still in really good shape to other kids."

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.
