    Size Down

    Wants to write this to save someone else some time :)

    I’m usually an XL in tops.

    I got a Brrr long sleeve, short sleeve, and hoodie in XL but exchanged for a L and it’s perfect (especially for working out)

    Thanks for looking out for your fellow customers, Victor! That's exactly the kind of helpful insight that makes all the difference when people are deciding on sizing. The RTX® brrr° cooling fabric is designed with a performance fit, so sizing down often gives that perfect athletic cut for training without being restrictive. It sounds like you found that sweet spot with the Large across all three pieces. We really appreciate you taking the time to share this sizing tip!

    YMMV, not an indictment, just honest feedback given use case.

    So, when it comes to this top I can approach my review from two different sides. The first is the out of the box feel and fit of the garment. On that level I'd say it's easily 4.5 stars with the only recommendation for the overall body to have slightly more form fit, only still not compressed to your skin. The second perspective is with all namesake and marketing in mind, which is where personally I don't necessarily have any actual experience where this fabric has felt cooling at all. Maybe it requires more sweating than I'm physically capable of at this time due to medical recovery, I'm not sure. Only thing I can be certain of is that the brrr concept and technology might not be something that bears calling attention to itself for the sake of selling products.

    Hi Calvin,

    Thanks for the honest and detailed feedback about the RTX® brrr° COOLING TRAINING CREW LS and for sharing your experience with both the fit and the cooling performance! We're glad to hear that you're appreciating the out-of-the-box feel and fit quality, and that it's hitting that 4.5-star mark on construction and comfort.

    We sincerely appreciate you bringing up the cooling technology performance and how the brrr° fabric hasn't delivered the cooling sensation you were expecting based on the marketing. Your feedback about the cooling effect not being noticeable during your workouts gives us valuable insight into how the technology is performing across different activity levels and individual physiology, especially considering your current recovery situation.

    Thank you for your valuable input about both the cooling performance and fit preferences, alongside your positive feedback about the overall construction quality. This helps us focus on evaluating how we communicate the cooling technology benefits and ensure we're setting realistic expectations for the performance across different use cases and activity intensities!

    Expensive? It's Time For People To Put Their Money Where Their Mouth is...

    Everything Origin Makes is great. Really good material and workmanship. Nothing more important than Made In USA. There is nothing Green about imports. Buy local and buy often.

    That's incredible that the RTX® brrr° COOLING TRAINING CREW LS is delivering that kind of year-round versatility for you, Kirk! It's amazing to hear that you're getting 365+ days of wear out of it!

    We love that you discovered how surprisingly effective it is for layering in winter too. That brrr° cooling technology is engineered to regulate temperature in both directions, so it makes sense that it's working as that perfect base layer when the weather gets cold. And the fact that it feels smooth and moves with you no matter what you're doing really speaks to the RTX® construction.

    Having 8 pieces and still wanting more is the ultimate compliment! It sounds like you've really dialed in that perfect system across the shorts, long sleeve, and hoodie versions. When you find gear that performs like that across every situation, it's hard to go back to anything else.

    Thanks for putting our gear through its paces every single day!
