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.

    Great Shorts

    Love these! They are super comfortable and perfect for hitting the gym, but also great for just hanging out in the yard or chillin' at the pool. Highly recommend.

    The Perfect Pair

    I knew polling these bad boys out of the bag they’d be legit. And they are. I’ve been training with another big brand and was stoked to get a pair of these when they rolled out. I’ll be picking up some more of these. Let’s go!

    Great training shorts

    Excellent flex, good length --so good I bought two pair. My only complaint would be the lack of any small zippered compartment (for a locker key, etc.), but the pockets retain contents well, so it's not a big deal.

    Hi Gordon! We’re stoked to hear the ORIGIN RTX® NANORIP TRAINING SHORTS are performing well for your training sessions—buying a second pair is the ultimate compliment! We really appreciate the feedback regarding a zippered compartment for keys or small items. We're always looking for ways to level up our gear, so we'll definitely pass that suggestion along to our design team. Thanks for supporting American-made!

    The only shorts my husband wants to PT in now

    Gave these to my husband for Christmas and they’re great. Good quality. He goes anywhere between a 30 to 32 inch waist, depending on what he’s training for and could probably wear a small or medium.

    IYKYK...... 365 days a year ?

    Let's just say in a perfect world the true function most days of the year are a nice solid Brrrr & Kilo Lite hoodie on top, and quite possibly the best shorts, LIKE, EVER paired with them ! People see you and think "when I grow up, I'm going to rock that 100% made in the USA and stop trying to fit into shapes made far far away that have no possible HOPE of ever fitting me !!!

    Buy multiple colors--you don't want to be sadly sitting in front of the washer and especially dryer HOPING they get finished soon ! Don't be that person-- Seize The Day !!!

    It's awesome to know you've found that perfect layering system with the Brrrr and Kilo Lite hoodie on top for year-round comfort. There's nothing better than having that go-to setup that works in any season and makes you feel confident every time you put it on.

    Thank you for supporting American manufacturing here at Origin!
