Underwear and Undershirts, Perfected

Presenting seven well-made pieces that will make your base layer your favorite layer.

ExOfficio Classic Give-N-Go boxers ($26)

With a blend of quick-drying nylon and spandex, the Give-N-Goes breathe naturally and dry fast. Bonus: antimicrobial treatment fights funk.

Icebreaker Anatomica boxers ($40)

These shorts use one of Icebreaker’s lightest and softest merino wools, plus 4 percent Lycra in the weave for a stretchy, durable, body-hugging fit.

Mack Weldon Silver boxer-briefs ($34)

Silver antimicrobial fibers have been a core odor-fighting strategy in base layers for more than a decade. Mack Weldon brings that level of tech to everyday underwear.

American Giant Classic Pocket T-shirt ($25)

This versatile, layerable piece is crafted from sturdy 4.8-ounce jersey cotton. It’ll last longer than almost any other T-shirt out there. 

Hugh and Crye White Pocket Tee ($20)

Use Hugh and Crye’s online fitting tool to find a 100 percent cotton top that slides on almost as well as a custom-tailored one. 

Buck Mason Natural Crew Pima T-shirt ($28)

The lightweight, 100 percent cotton knit of this fitted crew is pillow soft and gets softer with every washing. 

Patagonia R0 Sun shirt ($45)

It isn’t quite a tee and not exactly a rash guard. But with UPF-rated polyester, it works great as both.
