Bomb & Dave - are you both sitting down, as this news may make you both giddy & dizzy

: ASDA now do 300 denier in BLACK mmmmm, I use them under my leathers and they are toasty and silky

. I would imagine they are a tad more manly than 30 denier (thickness) american tan numbers

. You realise boys that we will want a fashion show of you both in your tights

.
On a more serious note a polo neck and a neck buff is also a good way to stay warmer
