I use blue plastic car wash gloves from Halfords £2.99 last about 2 - 3 weeks, not to tight a fit, so you can take them off quickly to collect money or write in books.
If really cold, then can wear a pair of wollen gloves underneath them.
I wear them all year round.
It's not so much the cold, it's to protect hands from fibre-glass shards off of the poles as they begin to wear, and from reeling in the hoses, they really do wear your skin.
When customers say isn't it cold today, I say yes look it's turned my hands blue
Blessings,
Graeme
