    RTX

    RTX shirts are my favorite shirt for basically everything - from climbing Katahdin to putting down bass lines in the studio. 10/10. My only question is what happened to the normal RTX hoodies? I only see the brrr ones now, which are great for summer, but you should bring back the normal ones too, which are great when things get cooler.

    Excellent fabric and material. I had to return because the neck opening was too large. Im athletic build without the neck of a pitbull ha. Return process was very simple and easy with $10 extra for store credit.

    Won't buy Under Armour anymore

    I was a big Under Armour guy for training gear. No more. These shirts fit perfectly. I have a long torso and this shirt still hits at the waist. My new go-to workout/exercise shirt
