Size Guide

Specially designed for temperatures in the 60°s. Latitude adjusted for the 40°s. Think San Francisco, Biarritz, Madrid, Milan.

Want to extend t-shirt weather a few degrees? You can with the 60°/40°. It's warmer than most t-shirts, but it's also less likely to become uncomfortably warm. We strike this balance by using a special french terry knit, ring spun cotton fabric. The tiny loop-threads on the inside of the garment create air spaces for warmth, and pull vapor outward where it can evaporate away from your body. And a generous hem prevents drafts from pulling warmth away from the body.

For ideal layering and a lightweight feel, we used raglan construction and a special contoured sleeve.

The result: A more stylish look. More comfortable layering. No billowing excess material.  No spongy, bulky knit material.




The Elastic used in conventional underwear applies constant, squeezing pressure. This causes it to creep, usually upward, into uncomfortable positions. For boxers this occurs at the waist. For briefs, this can occur both at the waist and at the legs.

Our NoLastic approach removes what you don’t need and don’t want: creeping and bunching.
