There is only one of these tees available, and it is MEDIUM as described in the item name.
The Simply Parkour Tee is quite possibly the “truest to Parkour” tee we have ever produced. Building on the simplicity and purposed foundation of Parkour, the Simply Parkour Tee is an elegant design that is both cool and straightforward, but it’s also complex because it speaks to the philosophy of Parkour. Consider it the newest best way to show your dedication to the discipline we all love. Made on our super versatile Take Flight Style Cut 4.3 oz 100% cotton tee. Super soft and relaxed, durable and extremely comfortable. Great for training and just hanging out.
