Oakley Men's Oo9239 Crankshaft Rectangular Polarized Sunglasses for Driving, Running & Outdoor Sports - UV Protection, Lightweight Frame

I'm writing this about my second pair of Crankshafts. The first pair lived a hard life for over four years and just wore out, and I didn't want to replace them with anything else. Extremely comfortable, light and durable, they stand up to mishaps (my first pair had a few) and just keep working.The earpiece hinge is an excellent design that just seems unlikely to wear out; if twisted, it just comes apart instead of breaking and can easily be pressed back into place. When the lenses get scratched, there are high-quality replacement lenses available in many colors, mirrored, polarized, the works, so as long as the frame holds up you can keep a pair of these fresh and functional almost forever.The one small downside, other than the high price, is that when folded the glasses are still a little bulky for a pocket. I've gotten used to it but they will take up lots of space when you're not wearing them. Oakley includes a microfiber bag for storage, which protects the lenses when pocketed without adding extra bulk or weight.Overall, these are top-notch sunglasses at a price that is high, but reasonable for what you get. I would have spent this much on multiple replacements for cheaper glasses over the past four years. Recommended.
