Our top pick is the Under Armour Performance Tech Long-Leg Boxerjock, a long-leg boxer brief whose listing names chafe-free seams and a no-roll hem. Every pair in the Amazon results we read was cut for men, so this is a guide to running underwear for men.

How to choose running underwear for men

  • Skip cotton. iRunFar says to avoid cotton, which absorbs moisture, holds sweat and can lead to chafing, and to look for polyester or nylon that stretch, wick sweat and dry quickly. Weeviews makes it the first of its five tips: never wear cotton underwear while running. Every pick here has a listing that names a performance, mesh or synthetic fabric.
  • Seams and tags. Runner’s World looked for underwear without seams or tags to reduce chafing, and iRunFar says flatlock seams can help. The listing of the Boxerjock names chafe-free seams, the ExOfficio lists flatlock seams, and the adidas lists smooth stitching and a tagless waistband.
  • Cut. iRunFar says briefs or boxer briefs suit runners whose shorts have no liner, and that boxer briefs for running fit snugly instead of loosely like regular boxers. It calls fly or no fly a personal choice: the New Balance has no fly and the SAXX has one. Weeviews suggests trying briefs too, which is the Reebok cut.
  • Fit and stretch. Runner’s World favored fabrics with more spandex or elastane for stretchy support. iRunFar says the fit should be snug but not restrictive, and that a wide waistband helps underwear stay put on a long run. Weeviews advises checking the fit before a long run, and Amazon’s own summaries are mixed on sizing for the adidas, the Reebok and the ExOfficio.

What we left out, and why

We read 120 search cards, 96 organic, and read the pages of 10 finalists. Four finalist links redirected on load to a sibling listing of the same pair, and we used the page Amazon served. We kept six and left out:

  • New Balance Men’s Performance Boxer Briefs. Five listings with this title show one shared rating total, and the page does not say whether they are colors and packs of one pair or different styles, so we left it out rather than lean on a total that may not describe this pair.
  • Under Armour Performance Tech Brief 6-Inch 3-Pack. A second pair from the maker of the Boxerjock, doing its job, with a rating total shared across several listings of the same title.
  • Hanes Performance Stretch Boxer Brief Pack. A polyester boxer brief with the same selling points as the adidas. Hanes boxer briefs for everyday wear are in our guide to underwear for men.
  • PUMA 5-Pack Performance Boxer Briefs. Another polyester and spandex boxer brief with the same pitch as the adidas and the New Balance, so we kept one pick per job.

Runner’s World, iRunFar and Weeviews all review running underwear for women as well as men, but the finalists we read were all cut for men, so women’s running underwear would need its own research. Runderwear’s running briefs for men appear in the Amazon results but were not among the finalists, and iRunFar’s top pick for men, the Patagonia Sender Boxer Brief, was not in the Amazon cards we read.

How we researched

On October 5, 2026 we read 120 Amazon search cards for “running underwear”, 96 organic and 24 sponsored. AI compared them, set aside sponsored repeats, compression shorts, thermal layers, cotton or modal boxers and listings that share one set of ratings across styles, read the pages of 10 finalists and chose six synthetic underwear for men. AI wrote this guide from that research.

Listings change: we read them on October 5, 2026, and a size, color or seller may differ today. Fabric and seam wording is the listing text as we read it, which the collector cut to about 200 characters per bullet. Every finalist was cut for men, and none of the top Google results for this topic was a Wirecutter page.

Prices, ratings and review counts come from Amazon and were read on October 5, 2026.

Frequently asked questions

Do you need special underwear for running?

Not always. iRunFar says many runners now skip underwear because running shorts usually include a liner. For shorts without a liner, or for extra support and protection, it recommends briefs or boxer briefs. If you wear underwear, avoid cotton: Weeviews and iRunFar both say it holds sweat and can lead to chafing.

Are boxer briefs or briefs better for running?

It is a personal choice. iRunFar’s picks are all boxer briefs, which fit snugly and cover the upper thigh, while Weeviews says briefs and jockstraps are worth a fair try. The Reebok is the brief here, and the Boxerjock is the longest boxer brief.

What fabric is best for running underwear?

Polyester or nylon with spandex. Runner’s World found nylon and polyester wick moisture about equally well and favored blends with more spandex for stretch, and iRunFar lists polyester and nylon as the fabrics that stretch, wick and dry quickly.

How should running underwear fit?

Snug but not restrictive, so it does not ride up or sag. iRunFar suggests a wide waistband for a long run, and Weeviews says to check the fit before a long run.
