I’d really, REALLY suggest not cycling in cotton shirts. When they get wet, they stay wet. And cycling in wet clothing can cause sores that will bench you. Buy a decent quality cycling jersey that features fabric that wicks-away moisture. The cycle jersey pictured is a custom one I created at owayo.co.uk (owayo.com is their US site) using their cutting-edge 3D Designer tool. They have pattern templates you can apply (I chose paisley for my jersey) and upload logos & artwork which you can place on a 3D model so you know how it”s going to look when delivered. All Owayo’s jerseys feature their “Ultra-Dry” fabric which I can tell you works. And the cost of a custom Owayo cycle jersey is comparable to a non-customisable one. And unlike other companies that allow you to create custom jerseys, Owayo has no minimum quantity: you can order just a single one. Disclosure: I’m an Owayo Ambassador, so have a relationship with the company. But I wouldn’t recommend them if they weren’t good.
