lol $50, i wish. the adidas store is selling the flannel for $280+ tax cdn. so around $260 USD. in other words, too much for a shirt
The flannel is made out of Diaplex, it's far a more advanced technology than Goretex (diaplex.com if you're curious).
I'm not saying the price is ok mind you, but it's more than just a flannel shirt - this is leading edge technology here.
