The shop ones do have the 'buff'. Saw it in WHS this morning. Had no idea what a 'buff' was - assumed it was a rag for buffing up your shiny frame as that's what it looked like. You people wear those things?

Very useful things buffs. Doubles (triples? quadruples?) as a scarf, lightweight hat, face warmer, fly and midge excluder (worn up over the mouth), head band, hairband, bandana, headscarf.... I'm sure in an emergency it could be used to bandage a limb, or hold on a dressing. Or even, to polish your bike...
As is often the case, a very simple idea that works on many many levels. Actually, it's a bit like the Douglas Adams theory of a towel.
