Size Guide

Reviews Summary
Customers say this long-sleeve shirt fits well with a comfortable, loose feel and lightweight material that's great for workouts and outdoor activities. Many reviews mention its cooling properties and breathability, particularly effective in hot weather and during exercise. Users appreciate the soft, smooth fabric and find it versatile for layering or wearing alone. Common feedback includes praise for the athletic fit, though some note sizing runs large and recommend ordering smaller. While most find it durable for active use, a few mention concerns about pilling and loose threads after initial wear.

    Great shirt

    Perfect for the boat or for building houses for a charity in Tijuana, Mexico - have used it for both. Size is fit but not tight. Already bought another.

    Hi Matthew, thanks for the awesome review! We love hearing that the RTX® brrr° Cooling Performance Crew LS is working great for you out on the boat and during your charity work in Tijuana. That's exactly the kind of versatile performance gear we build for. Thanks for grabbing another one and for being part of the Origin family!

    Lots Of Marketing, Not A Lot of Results

    These Shirts Are Ok To Be Fair. The Cooling Effect Is Placebo And Is Not Really A Thing, Fit Is Slightly Weird Where The Arms Are Almost Longer Than To The Waist. If You Have Even Slightly Broader Shoulders, This Will Affect You.

    Thanks for taking the time to share your feedback, Sam. We appreciate your honest thoughts on the cooling technology and sleeve length proportions. Your input regarding fit for broader shoulder builds is really helpful, and we'll share this directly with our product team as we work on future iterations!

    Great product!

    Initially, I bought the XL, but it was a little too baggy for me. Origin quickly processed the return/exchange, and the L fits much better for this type of garment. I wear it as an underlayer with my officiating gear for cooling and sun protection. Normally, their XL size fits me spot on, especially when it comes to their cotton hoodies.

    Hey Tom, thanks for the 5-star review! We're glad the L is treating you right and that our team made the exchange process smooth for you. It's awesome to hear the ORIGIN RTX® brrr° COOLING PERFORMANCE CREW LS is working perfectly as an underlayer for your officiating gear. We appreciate your support and trust in Origin!

    Get one size up is probably best
