They are stiff, but I still find them cool and comfortable because I don't wear it super tight on my wrist. It kind of makes them the coolest of the bands to me because since they do sort of maintain an oval shape when they are buckled, instead of being flush against my wrist, there is some air flow.How are the Woven Nylon bands? I don't think I've ever even felt on before? Are they soft and flexible? They look kinda stiff, but being Apple, I'm sure they are comfortable.
