My Bolle Paroles are 9 years old, and going strong. New nose & ear pieces to replace perished ones (sweat & suncream are bad for the soft bits, but don't seem to affect the frame or lenses), is all. Survived a faceplant into a metre of snow once when skiing (I had to take them off to remove snow from behind them, but they stayed on my face), a rib-cracking crash off-road, & much more. Being sat on does not seem to be fatal.
I love 'em. Weren't cheap, but with all the lenses they came with (clear, dark, mid-brown, pink for white-outs & low-light yellow - one of which I bought separately, either the clear or the yellow - I forget which), the time they've lasted, & what they've survived unscathed, I reckon I've had my moneys worth, & they don't seem to be about to give up the ghost yet. A few more years to go . . . .
They're officially discontinued, but there's a rather similar replacement, & I think replacement lenses are still available, if I scratch any of them too much. If they die, I'll buy something as similar as possible.
