    Almost perfect

    I wanted to come write a review because I was asked about sizing and said it runs small, but I wasnt able to provide any detail. I normally wear an XL t shirt, but the XL in this is too baggy around the torso. I am 6'2", 200 pounds with a mildly athletic build. 47 in around the chest, 34 inches around the waist at the belly button, 16.5 inch arms. I only include those measurements so i can say the shirt in size large fits all of that perfect. My only issue as far as fit is the length. It may be just be a problem with my specific build, being a little taller. But as soon as I raise my arms at all, it comes up above my waistline and exposes skin. Obviously a bit of a problem with a shirt designed for training, like doing pullups, overhead lifts, etc. Other than that little problem, the shirt seems to be well made and looks good. I just wish there was a little more length, or maybe a change in the cut to prevent it lifting up.

    Hi Zach,

    Thanks for the detailed feedback about the ORIGIN RTX® brrr° COOLING TRAINING CREW SS and for taking the time to share your specific measurements and sizing experience! We're glad to hear that the Large is hitting the mark perfectly for your chest, waist, and arm measurements, and that you're appreciating the construction quality and overall look.

    We sincerely appreciate you bringing up the length feedback, especially how it affects functionality during training movements like pullups and overhead lifts. Your input about the shirt riding up when you raise your arms gives us valuable insight into how our current cut and length is performing for taller athletes and training-specific applications where arm mobility is crucial.

    Thank you for your valuable input about the specific fit characteristics and how they affect real-world training use, alongside your positive experience with the overall construction and appearance. This helps us continue evaluating our length specifications and cut design to ensure we're delivering the full range of motion coverage that matches the quality performance you're experiencing with this training shirt!

    Premium Athletic Shirt

    I primarily wear Vuori shirts for running, biking, lifting, and everyday wear, but this shirt rivals any from Vuori. The material is soft, breathable, and overall high quality. Love the ice color and need to get some more!

    Daniel, that's exactly the kind of comparison that tells us everything about how the ORIGIN RTX® brrr° COOLING TRAINING CREW SS is performing!

    That combination of soft feel, breathability, and cooling technology is precisely what makes this crew such a standout for everything from intense training sessions to everyday wear. The ice color really does hit different too, it's one of those shades that just works perfectly with the cooling tech and clean design.

    Sounds like you've found a new go-to that can handle whatever you throw at it, whether that's crushing a workout or just moving through your day. These crews are built to deliver that same performance every single time you reach for them.
