Size Guide

Reviews Summary
Customers say these training shorts are comfortable, durable, and perfect for various workouts including weightlifting, running, and martial arts. The stretchy material moves well during squats and lunges, while the wide waistband stays secure. Many appreciate the deep pockets and lightweight feel. Common feedback includes praise for the build quality and construction. Some mention the material feels different initially but improves after washing. A few note sizing runs slightly small, particularly in the seat and leg areas, with some recommending ordering a size up. Several customers wish for more color options beyond the current selection.

    Favorite Shorts

    Easily my favorite athletic shorts. I started to complain because there were only 2 colors when I ordered my pair. A week later they added many other colors. I will be buying more.

    Best gym shorts I own

    I do mostly powerlifting and triathlon training, and these are perfect for me. 32” waist with a medium was perfect.

    The fit is perfect. These shorts are incredibly light weight, durable (stretch), and so comfortable in heat and sweat!
