Yes, great idea. I sent off for a second one today. Well, actually 3 second ones, for me, Mr F and eldest grandson who cycles. I did also buy a polar buff but mine is completely lined with fleece and strangles me a bit, so Mr F has that too.
The original Buff is surprisingly warm, even just worn around the neck to stop giraffes getting down
. Otherwise I pull up the front over my nose and it's as warm as a thick scarf, but not so restrictive.
