I'm Japanese, so it's hard for me to find a well-fitting pair of sunglasses. I've tried so many brands like Smith, Anon, Native and Ray Ban... but nothing compared to the comfort of my Frogskins. These sunglasses don't weigh a thing either... unfortunately,this is the very reason I lost mine!! :(
I was hiking around the local crag to go climb, and I must have taken a hard step and they slid off my head and into a little crevice that I couldn't get to! Haha, of course this is all my fault, but it'd be maybe nicer if the inside of the arms had something a little more sticky.
Overall, the best pair of sunglasses I had ever owned.
