Collection: Long Sleeves — versatile layers for all-season comfort Cotton long sleeve T-shirts.

Men's long sleeves, cotton-led across every style

Six long-sleeve styles, and cotton leads on all of them, running from 57% up to 100%. The True Boxy Fit Long Sleeve Tee, True Heavy Boxy Fit Long Sleeve Tee and Casual Sport Long Sleeve Polo are 100% cotton; the Everyday Long Sleeve Turtleneck pairs 57% cotton with 38% TENCEL™ Modal.

What separates the six?

Weight and neckline, mostly. The two True Boxy Fit tees are the plain crew necks, one cut heavier than the other. The Everyday Long Sleeve Turtleneck comes up the neck. The Casual Sport Long Sleeve Polo and True Relaxed Poplin Shirt both open at the placket, one knitted and one woven. The Waffle Raglan Long Sleeve is textured, with a raglan shoulder seam rather than a set-in one.

The fabrics

Cotton is the main fiber on every style, between 57% and 100%, and the balance differs more than the names suggest. Three styles carry no blend at all. The Everyday Long Sleeve Turtleneck is the outlier, at 57% cotton with 38% TENCEL™ Modal, which is a different cloth from the rest of the page. The exact split for each sits on its own product page, and our materials page explains how we choose the fibers.

Colors and sizes

Thirteen colors, including Black, Evergreen, Grey Melange, Sandstone, Seaweed, Slate, Stone Blue, Truffle, Walnut and White, plus two stripes. Sizes run XXS to XXXL. Some styles are also sold in packs of three, six and nine — a pack is a quantity, not a different garment.

What else sits alongside

The short-sleeved versions are on the men's T-shirts page, the joggers are the matching bottoms, and the socks sit in the same cotton family.
