The Best Men's Underwear to Buy for a Comfortable, Supportive Fit

This underwear from Tommy John is full of innovative features that stood out in our Textiles Lab evaluations. Tommy John is known for its modal and spandex blend fabric that's impressively smooth, soft and breathable, and testers said it was the perfect weight — not too thick or too thin. We and our testers also appreciate the wide no-roll waistband stays securely in place without bunching and the horizontal fly for easy access during bathroom breaks. Another unique feature is the contoured pouch that's designed to provide support without feeling restrictive.

When we asked our testers what they disliked about this underwear, there were zero complaints, and several testers said they planned to stock up on more pairs. Our only caveat is the limited color options and low inventory due to selling out so quickly. If you're still not sure about buying a $36 pair of underwear, know that Tommy John offers a "best pair" guarantee, which means the brand will issue a refund for your first purchase of one pair of underwear if you don't end up loving them, even if they've been worn and washed.
