Denim brands are offering straightforward sizing for muscular physiques. Keirin Cut’s jeans are roomier in the seat and thigh, with a slightly tapered leg opening and added stretch for comfort. Styles include straight cuts for women and relaxed leg for men. The brand expanded into chinos last year, applying the same generous fit to work appropriate bottoms.

The brand collected measurements from nearly 100 athletes to inform its jean design, and uses real athletes as fit models. Plus, athlete feedback gets incorporated along each step in the process.

Barbell jeans are created to fit the wearer’s actual waist size. Jeans are made with Barbell’s advanced flexible denim and high tensile-strength stitching. Boot cut and slim options are available for women; straight and relax fits are offered for men.

BeBop Society Denim was founded to solve the problem of ill-fitting denim for men with muscular legs and to redefine premium denim by making great fitting jeans accessible to all men. Its jeans are made with selvedge stretch denim and are designed with a generous fit in the seat and thighs for waist sizes 30-38. Heritage details include custom hardware, selvedge pocket detail and seams.

Core Denim caters to fitness-focused women with muscle tone and build in the legs, hips and waist. The brand offers two fabrics and two fits, each with the goal of offering more stretch and recovery than traditional denim.
