The Best Women's Quarter-Zip Sweaters Without Polyester

Updated November 9, 2026 · 6 min read

On Pinterest, "quarter zip women outfit" is up 4,500% from last year. "Alo quarter zip" alone is up 1,000%. The quarter zip has gone from a ski-lodge layer to the sweater everyone is wearing with wide-leg trousers and jeans.

Most of the quarter zips in that search are athletic ones, made from polyester or nylon with spandex. Those fabrics stretch and dry fast, which is why activewear brands use them. For a sweater you'll wear all day, all winter, a natural fiber does the job better: it breathes, it holds warmth, and it softens with wear.

A sweater that looks natural isn't always made of natural fiber. Of the quarter zips we checked for this piece, Paka's Quarter Zip is 65% alpaca and 35% recycled nylon. Woolx's Tori 1/4 Zip is 71% merino, 22% nylon and 7% spandex. Marine Layer's Chalet Quarter Zip Sweater is 53% cotton, 24% polyester, 20% nylon and 3% spandex.

So we read the label on every pick below. Here are six with no synthetic fiber in the knit, all in stock in a full size run on the day we checked.

What to look for on the label

  • Every fiber is a plant or animal fiber. Cashmere, merino, wool, alpaca, cotton. If nylon, polyester, acrylic or spandex appears anywhere in the fiber line, part of the sweater is plastic.
  • The fiber line, not the name. "Merino" or "cashmere" in a product name can mean a blend. We found the same thing in Abercrombie's merino sweaters, where the women's version was mostly synthetic.
  • A care label that says hand wash or dry clean. Natural knits rarely go in the dryer. If wool is labeled machine washable, it may be superwash, which we explain in What Is Superwash Wool?

What to skip

  • "Performance" quarter zips. They're built for running, not for a cold office.
  • "Cashmere feel" or "cozy knit." Those describe a texture. Only the fiber line tells you what it's made of.

The picks run from $104 to $525, across three brands. Four are 100% cashmere or merino and score 90. One is 100% cotton, for anyone who finds wool itchy. One is a wool and cashmere blend. The cards show exactly what's in each one.

How to wear a quarter zip

The looks on Pinterest come down to three pairings. A cream or white quarter zip with straight-leg jeans. A brown or taupe one with wide-leg trousers in a lighter or matching tone. A chunky knit over a long skirt. In each case the sweater is the warm layer, so what's under it can be as simple as a cotton tee.

The quarter zip is one sweater we'll keep reaching for long after the trend moves on. It's worth buying in a fiber that lasts as long. The same goes for the coat over it. Four of the nine women's wool coats we read are 100% wool.
