My main problem with sunglasses is I usually loose them.
R.I.P bloc sunglasses in some Norwegian Wilderness....
R.I.P sunglasses in a river in the French Alps....
R.I.P sunglasses on a bus in New Zealand...
For that reason I usually buy bloc but have never paid more than £15 for a pair. (TK Max, Cotswold Rock Bottom)...
I have some awesome Julbo cat 4 glacier glasses tho!
