I like that they are very light weight. the true test is yet to come while on vacation.light ,can bend over and they stay on ...fits m fat head......only one but when driving ,to check over your shoulder to change lanes the arm blocks my view …..so raybans for driving ….other than that I am really happy ,well I have using them for a year and they are still like new, that's wiping sweat of them with a shirt ,paper towel, cotton towel what ever and not a scratchI really like them but the sides of your eyes so sunlight and wind gets in but overall they're coolI love the red and polarization in the lens. The frames are flexible and should adjust to most any size head.Nice glasses, comfortable. The vision is clear on this. The only recommendation I would add is to put a cleaning cloth in. The case though is very nice.Great sunglasses!....Lightweight...sturdy...fashionable...reduces glare very well here in sunny Florida...came in a "hard" case, perfect for protecting them when they're in my golf bag...the price point is great and customer service is top notch!...Highly recommend!WOW. might have to buy another pair....The are great, look good and feel good on.
