We still have quite a few Adult sizes in our Krete Lunar Tee! These shirts are very long fitting and feel great to move in! We recommend maybe ordering a size down compared to what you would normally wear, because they run fairly big. If you like your shirts long and baggy then we recommend you order your normal size! If your subtotal is more than $40, make sure to use code KRETEGYM2023 to get free shipping!
