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.

    Solid Training Short

    The RTX NONORIP training short is well designed and fits per the sizing guide. The material has that indestructible feel to it.

    That's exactly what we aim for with the RTX® NANORIP TRAINING SHORT 9 INCH, William! We're thrilled to hear the fit is spot-on with our sizing guide and that you're experiencing that "indestructible feel" from the nanorip fabric technology. That durability is precisely what makes these shorts such a reliable choice for training and active wear. It's fantastic when the design, fit, and material performance all come together seamlessly like that. Thanks for the 5-star review and for choosing Origin!

    My new favorite shorts

    I love these shorts. The material and the fit are perfect and they are very comfortable. These are now my do-everything shorts. Working out, doing yard work, going to a ballgame. Give us more color options!

    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!
