Description

The Women's Vapor Long Sleeve Crew is a lightweight Merino Wool layer built for 4-season performance.

This long sleeve begins with natural, American-grown Merino Wool that is then spun and knit into our proprietary Vapor Wool fabric. Vapor wool combines three fibers to create a garment that is lightweight, soft, cooling, antimicrobial (odor-free), moisture-wicking and ultra-fast-drying. The Vapor Long Sleeve Crew is the perfect no-bulk solo layer or baselayer for high exertion activities.

The newly updated design offers a flattering crew neckline along with raglan sleeves to eliminate bulky seams on the shoulders. American-made with American Wool.

NEW FOR 2026: The vapor collection now features an updated vortex-spun yarn construction designed for greater durability, reduced pilling, and longer-lasting performance. This improvement strengthens the fabric while preserving its ultralight breathability and soft feel that continues to improve with wear and washing.

Reviews

Sizes are growing smaller

"I have a lot of Duckworth clothing, bought over the course of several years, and overall I would rate it as great quality. I like the total USA grown and crafted and am loyal to the brand for that main reason. However, I have experienced a shift in sizing. I'm a solid women's medium, and my older Duckworth tops were cut generously and wear comfortably. My latest purchase is a Vapor LS T shirt and it is snug to the point of (sadly) passing it over in favor of wearing something that isn't so tight in the arms. As my purpose for it was a base layer I'm not opposed to form fitting, but this one doesn't cut it for me."

Love

"I love it. The fabric is soft, and not too thin. I will mostly use it layering over top of tshirts. I’m taking one star off, because the shoulders and upper arms are a little tighter than I’d prefer, but it’s not terrible. I have broader shoulders than most women so this is a typical problem for me."

— Rochelle W. (4/5)

Vapor Tee is the softest well rounded addition to your go tos

"I love this shirt! I love both the short sleeve and long sleeve. I wish more colors were in stock, but this is the softest shirt that feels soooo good on your skin. I wear it all the time, but mostly for biking, both mtn and gravel. Try this out, you won't regret it. This is my fifth one. They hold up pretty well considering how much I wear them."
