Layer over double cuff shirt?

Base layer or traditional long John …

Don’t think so, but the sweaters are only for wearing at work over double cuff shirts

A tank top you say?
It has a certain following!

I think I’d rather freeze!!

Seriously the answer is clear.

Iron Maiden long sleeve t shirt under plain white shirt. Nice and warm and a good discussion point with your boss.

That guy is wearing double cuffs!

I am not an Iron Maiden fan sadly.

@mudshark I tried your suggestion a while ago, but thin wool jumpers don’t like being stretched over double cuffs. The jumper loses the fight fairly soon and turns into a saggy sack.

String vest. Seriously, the £30 castelli “string” underlayer I ride in, is simply fantastic.
