Jase reached out to let me know the order was going to be a bit later which I appreciated. Absolutely worth the wait! The quality of the shirt is awesome! It's simple, but with so much meaning behind it. I can't wait to wear it and see what other products come out (request for socks 🤩🤩?)! It's motivated me to get back into the swing of it. I'm keen to get fit for my wedding, with the support of the Circadian Strong family✨✌🏼💪🏼

I really love this tee: the look and everything it stands for. It's nice and light, holds it's shape well during a workout and breathes well.
