Not your typical mountain bike shorts.

Creating the perfect pair of mountain bike shorts is tricky. They need to be exceptionally durable, actually comfortable to pedal in for hours, and have all the right pockets and trim details. We spent years getting those things right with the KETL Skid Mark MTB Shorts in Twill.

The nylon twill is the same fabric we use in our Shenanigan Pants and Shorts. It’s durable, soft to the touch and super stretchy, with a denim-like texture and none of the swooshy noise. Lightweight, breathable and quick to dry, it’s comfortable for hours of pedaling and feels just as good hanging out after the ride.

The fit is purpose-built for being on the bike. A 12-inch inseam with a slightly longer front cut, plus enough room and stretch for knee pads. A higher back rise keeps you covered in the saddle, while a grippy waistband and full-length adjustable belt with a G-hook and snap closure keep the shorts snug and in place.

The two side zipper pockets face backward for easy access in the saddle. We obsessed over their placement to keep your phone and other essentials from jostling around with every pedal stroke. Two rear zipper pockets and two traditional front hand pockets handle the before-and-after-ride essentials. All six are lined with thin, stretchy mesh to keep them light, breathable and quick to dry.

Laser-cut ventilation at the crotch and above the rear pockets lets air flow where you actually need it. And a couple of accessory loops, one up front and one out back, give you a place to hang your sunglasses or keys.

And if you damage them, we’ll repair them for free, for life.

Wash & Care

These shorts are built to get dirty. When it’s time for a wash, empty the pockets, close the zippers, and wash inside out in cold water with like colors.

Use a mild detergent and skip fabric softener. Hang dry to help preserve the fabric’s stretch and extend the life of the shorts. You don’t need to baby them, but a little basic care will keep them in the riding rotation longer.
