Our beautifully soft 100% merino wool leggings are a rib knit, which combined with wool's natural elasticity ensures they stay up, stay on, don't sag and retain their shape year after year, wear after wear.

To get the most wear, we recommend you buy them up a size and just roll the cuffs up until those little legs have grown enough to roll them down. They are warm enough to wear alone and low profile enough to wear as a layer under other pants. 


  • Rib knit for stretch & growth
  • Temperature regulating
  • Anti odor and breathable
  • Easy care and quick drying
  • Okeo-Tex100 free from harmful chemicals

Composition: 100% merino wool, chlorine and mulesing free

Love these leggings!

These are such lush leggings for winter! They are so cute and are great casual or to dress baby up a bit (mine wore his on Christmas, etc!) They are so soft and cozy and I always feel happy wrapping my babies up in these when the weather turns chilly.

Best leggings

Thank you so much for these incredible wool leggings. My daughter loves them. I especially love the length. They can be worn bunched up or rolled up. I have rolled them and they have stayed put the entire day! I was worried they would unroll easily and be a nuisance but that is not the case. I love buying quality items that are beautiful and will last.

Soft, super warm, amazing.

We bought these leggings in deep sea color for our 1yo and 8yo. We loved these. We used them pretty much everyday as a second layer during our two week winter vacation. We are from a tropical weather and it was very important for us to keep our children, specially our little one, as protected (and comfortable) as possible.

Let me start by saying these are incredible soft. I know most merino wool products out there are advertised as super soft but these take the title home in our opinion. We bought several base layer sets for us and our children, all merino wool, and all from top premium brands, and while they were soft, Nui Organics was by far the softest feel. For the most important part, they did the job extremely well. We visited Canada and experienced temperatures down to minus single digits Fahrenheit (-26C). That is very cold for us. Let alone the feels like temperatures. Our baby was out for limited time at a time, but our 8yo used these for ski lessons and was exposed to these temperatures for several hours straight. We are certainly very happy with the performance.

We have so many good things to say about these leggings. They look beautiful in deep sea, they are super comfortable, they are stretchy so for us was ideal since we intended them as a second or middle layer, but might be a bit loose for first or base layer if you intend a tight fit. That being said, we did used it as base layer for both children sometimes in situations when the temperature was not as harsh or we were outside very limited time and it was fine.

One last thing I wanted to mentioned is that the fit was just right for both our baby and our older son. There is definitely room to grow since the leggings are longer than they needed and we would just roll them up.

We live in these!

Just like all the other reviews, I love these leggings! I bought the deep sea color in size 12-18m a couple months ago for my now 10 month old baby boy. The deep sea is beautiful- it’s a mixture of the colors pine and navy. My boy is about 28” long and 20lbs. I roll the cuffs up to his knees- it’s very low profile and not at all obtrusive when he’s army crawling and/or walking (with me assisting). The waist is a tad loose (not enough to slip down or fall off) which I prefer because who likes a restrictive waistband on their belly? No one. Like all Nui products, these are warm without the bulk, soft and comfy, durable, look great, and superb quality. I highly recommend these leggings (I have them too), they are seriously the best! We wear them daily!

So soft

We love these pants and our baby wears them almost everyday this winter. We were gifted 6-12 months and currently roll them up for our 6 month old. Definitely plan to get more as he grows but I think he will be able to wear this pair next winter. Love the color too
