Won't need these - it's too cold in here
One note - you might want a polycarb/plastic body, in case something bad happens that metal can cause a fair bit more damage.. I pretty much only use Bolle for cycling glasses too, far cheaper to replace when they inevitably get scratched.
I've never paid more than £8 for these from eBay.
Plenty of styles from Bolle to choose from at Screwfix with free click and collect, including these at £9.99
not UV protective?
