Best For Cashmere | Under $100 | Most Size Inclusive

1. NAADAM

Best For | Wide selection of cashmere and organic cotton sweaters
Ethics | Cultural preservation and environmental stability
Sizes Available | XXS – XXL
Prices Starting At | $98

If you want your cashmere to be 100% ethically sourced directly from Mongolian herding communities, then NAADAM is the company for you. Founded in 2013 by two college friends who traveled to Mongolia’s Gobi Desert and saw traditional cashmere traders inflate prices and hoard profits, the brand set out to change the industry by investing directly in herding communities and cutting out middlemen. The result is a transparent business model using circular design principles to produce premium cashmere at affordable prices. NAADAM offers a wide variety of contemporary designs, from quarter zips to cardigans. Fun fact: Their cashmere comes from the Zalaa Jinst white goat, the only completely white breed of cashmere goat in the whole of Mongolia. 

Our Editor’s Review | “Our team has long loved NAADAM for their thoughtful craftsmanship, and the Chunky Cotton Polo Sweater might be our favorite piece yet. The organic cotton is soft yet substantial, striking that perfect balance between cozy and refined. It’s become a true wardrobe staple — effortless, elevated, and endlessly wearable.” – Kayti Christian, Senior Content Strategist

Sourced sustainably from Inner Mongolia, this fabric is three times warmer than wool and designed to last for years. The best part? Quince’s cashmere collection is all priced under $200!

Our Editor’s Review | “The silhouette is extremely sophisticated. I feel wiser wearing this sweater and am reminded of the grace and modesty of my grandma. You can easily dress it up or down. I wore it at night with jeans and boots and felt put together yet casual. I ordered a small size and I love the fit. But, if you’re looking for it to be looser, I’d size up. “ – Courtney Jay Higgins, Contributing Editor [Read the full review.]
