To keep your item looking its best, gently machine or hand wash in cool water. Avoid soaking or bleaching.

THE CREW THEY WILL NEVER WANT TO TAKE OFF
THE LEGGINGS THAT KEEP THEM COMFORTABLE ALL DAY LONG
EVERYDAY VERSATILITY
One pair, endless comfort. The MerinoSilk Leggings blend softness with warmth, making them perfect for layering in cooler weather or wearing solo when it's mild. Whether it's playtime, school, or cozy downtime, these leggings move with them through it all.
QUALITY MADE TO LAST
Fast fashion isn’t made for kids. This is.
Made from a durable merino-silk blend, it’s designed to withstand every move, grow with them, and last through the years. Because the best clothes are the ones that don’t need replacing.
NUI CERTIFIED MERINO
Merino wool is nature’s performance fabric—naturally moisture-wicking, odor-resistant, and even flame-retardant, all without a single chemical treatment. Soft, breathable, and built to move, it keeps up with your child while maintaining comfort and sustainability.
But good clothes shouldn’t just last—they should live on. That’s why the MerinoSilk Leggings is part of our (re)Nui pre-loved program, giving families the option to pass it down, trade it in, and keep high-quality clothing in circulation. Less waste, more wear, and a smarter way to shop sustainably—because great clothes deserve more than one life.
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 MerinoSilk Leggings? It’s natural, breathable, and built to last.
