Oh, wow. Check this out. We are so ignorant in our part of the world where men are proud of their locks (or otherwise, just cut them off) - and either way, it's not usually "cool" to cover their heads, for heat, sun, cold or anything other than supporting your local union or team. Of course, these scarves serve all those purposes at the same time. Am I rambling? I find this a really interesting different lifestyle, myself.
