Sunglasses are one thing that I don't scrimp on. I find that the cheap ones aren't reliable and you end up having to buy new ones in 3 months. IMO, it's much better to buy one really good pair then 3 or 4 cheap ones.

Don't scrimp on sunglasses. Some of the knock offs don't have UV protection, and I'd rather do a faceplant on concrete wearing Oakleys than some unknown protection. I did that once and the only thing that saved my eye was the Razor Blades I was wearing. (1990's)
