One short for all the ways you train

This lightweight training short is built with quick-drying four-way stretch fabric, a durable water repellent treatment, and a matte finish that looks as great as it feels. Redesigned with deep hand pockets, a hidden zippered back media pocket, and an overlapped side split and gusset for total range of motion during sprints, squats, and sun salutations. Put 'em on and go—the breathable built-in boxer brief is designed for comfort and support without being restrictive.

  • Built-In Breathable Boxer Brief Liner*
  • Four-Way Stretch
  • Durable Water Repellent Treatment
  • Mesh Front Pockets
  • Hidden Media Pocket
  • Overlapped Side Split & Gusset Construction
  • Available in Short 6" and Standard 8" lengths


Designed with a modern, athletic fit. The built-in liner is supportive without being restrictive. We recommend sizing up if you’re between sizes or prefer a more relaxed fit.
The Standard length has an 8-inch inseam and the Short length has a 6-inch inseam. Both versions have the same dimensions in the leg opening and waist.
See size guide below for details.

Great shorts
I love the fit of the shorts, they look great too. The liner is a great option for activity, without having to worrry about slippage. I also love the shorter inseam. The only thing bad, contrary to what I thought, given most modern clothiers, the shorts fit true to size, not slim. So I bought a size, while fitting, a bit too big for my taste.
I rock these multiple times a week for hot power yoga. The mesh liner lets everything breathe while still giving great support! The length and style allow me to grab a casual meal in them post-athletics too. I also run in these but I usually use the Switchback short as it's built for longer runs. Great weight on these too!
These shorts are fantastic — wayyy more comfortable than my usual Nike dryfits, and they stretch without seeming flimsy or cheap. Easily my favorite kit + will be buying more.

About Myles


Myles was founded by a group of friends who never understood why athletic apparel always seemed to fall into two categories: old sweats and tees that have been relegated to “gym clothes” status because they’re too tattered or ugly to wear anywhere else, or overpriced “high-performance” gear you’re almost afraid to sweat in and looks ridiculous outside of the playing field.

We wanted to change that, starting with the dream of creating the perfect athletic short—a pair versatile and stylish enough for workouts, the outdoors, and around town. We went to work collecting fabric samples and visited a garment manufacturer down the road from our home in San Francisco to get prototypes made. After many tweaks and test runs, we were ready to launch our four-way stretch Everyday Short. We asked experts from the likes of Esquire, Gear Patrol, and Men’s Health to put them to the test, and we soon learned we weren’t the only ones ready to ask for more from their clothes. A few years and whole helluva lot of shorts later, Myles has grown into a full line of activewear made for making moves anytime, anywhere.


Our mission is to deliver a fresh perspective on fitness and inspire stylish, healthy(ish) lives. We think there’s more to living an active lifestyle than the relentless pursuit of personal records and six-pack abs (though, hey, we’ll take ’em). We hope to build and empower a community that shares our belief that fitness is a lifetime journey and not a means to an end. From morning runs to evening pick-up games, Myles Apparel is made to enhance the best parts of your day (and look great doing it). Check out the Myles Run Club to get involved—we’d love to meet up for a run and a beer sometime.


We combine cutting-edge fabrics with timeless styles to create activewear worthy of being a wardrobe staple. We design every piece in our San Francisco office and test them on our morning bike commutes, weekly office workouts, and trail runs through the Marin Headlands. All of our styles forgo gaudy graphics and colors in favor of functional details and classic looks that stand the test of time.
