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.

    Best shorts

    I wear this everywhere. I wear them to BJJ, the grocery store, to the pool, and while running errands. I ordered both the 9 & 7 inch. The wife loves the 7” ones. Sky’s out thighs out she says… Please make a camo pair of these!

    Great training shorts!

    Perfect shorts for the gym workout, running, rucking, relaxing and everything in between. Has some stretch for comfort. Great fit, good size pockets. I like the material, it feels durable but yet comfortable.
