Why don't you tell me what you really think? :-)

I do not possess a single long-sleeved shirt of any description. In cool weather I wear a sleeveless gilet (Mountain Warehouse) over a short-sleeve shirt. In cold weather I chuck a waterproof on top. I live in a place where the daytime maximum rarely fails to reach 10°C, even in mid-winter. I estimate that, when I'm out and about, any wristband attached to my person would be visible for all to see on at least 320 days of the year. Thank you.
