As soon as I saw it I knew it must be Dashing Tweed. I've occasionally been featured in Guy's promotions; a top bloke. Keep flying the flag! If anyone is into, or looking for an interesting flat cap check his stuff out. Something not mentioned is that Guy weaves his own textiles and has 3M scotchlite reflective material woven in, so for cyclists you're a little more visible. Little wrong with two wheeled sartorialism.
