Really love it. Very comfortable and lightweight. I driving above 2 hours every day and my eyes don’t get tired. This brand is really good.Look even better than expected.Great sunglasses. Need non polarized lenses due to my job. Ordered because they are advertized as “Non Polarized”. Definitely polarized. Kept them, however, because they are fairly light and overall a great set of sunglasses, especially while driving.IMHO these glasses are for smaller adult faces. They are very fitting. The lightest weight glasses I have. On the negative side they do not get very light tint for low light conditions. The arms are very thin and are hard to put on with one hand. The arms flex quite a bit so I need toe hands usually to put them over my ears right. Love the lightweight. They are definitely polarized so it is hard to see screens in car or on phone. I wanted a bif transition range to go from darker forest to bright sun while hiking. I would not wear in alpine or snow sun conditions but would all else. Wish they would transition more light tint in darker conditions but that may be a Lot to ask since the strong sun protection is the most important feature to me. I don’t squint with these and have light sensitive eyes. I think they are expensive. I have had for a few spring months so durability with such thin and flexible arms is to be determined.Having gotten several years excellent use from glass-lensed Serengeti drivers and 555nm polarized sunglasses, when the frames on those finally broke it was time for replacements. I decided on the plastic lensed, more wrap around styles. First, I got the Maestrale in Drivers Polarized. Really love that one! I wanted something neutral for bright, clear days, and also when doing photography, so thought I'd try the newer Erice in the CPG lens. I will compare the two... (Note - This review appears under the Erice model also.)The main attraction is that the Erice is more open on top, so ought to ventilate and not fog up as much as the Maestrale. Surprisingly, it is not any better in practical use! Still fogs up easily in certain situations. Also, my eyebrows generate a lot of oil, and I have to clean the Erice as much or more than the Maestrale. The eye-side of the lens on the Erice is coated to reduce reflection, but this also makes it more "sticky" to clean.On the other hand, the Maestrale, with it's closed bar across the top, really hugs the eyebrows and keeps the sun from peeking of the top.The frame is thicker and rounds outward a bit more than the Maestrale. Sometimes this interferes with winter hats, etc. Also, it weighs a bit more, so won't stay on top of my head as well as the Maestrale. The Maestrale frame also gives a clearer view when you look towards the nose.Ultimately, I like the Maestrale better and hope they keep it in the line for many years to come!By the way, both units come with the same semi-hard case and cleaning cloth, and both are made in Japan. They cost me about the same, too.UPDATE: The left side frame arm broke off. It didn't seem to have been physically damaged. Indeed, I now see that where the arm connects to the corner hinge is very thin. I contacted Bolle, the US distributor for Serengeti, and after 12 days have only gotten an automatic "please wait we are busy due to Covid-19" reply. I expected a response by now, and hope they can provide a replacement part because the sunglasses are in good condition otherwise. Meanwhile, I am wearing the Erice model all the time (it is usually my backup).I first looked at Serengeti sunglasses 20 years or so ago - but back then, being a poor university student, there was no way I was affording them. They sure were lovely lenses to look through though, and ever since then when I'd been thinking about sunglasses, I'd always remembered how good that pair (glass lenses) had looked way back when.Fast forward to now, and my Adidas polycarbonate sunglasses were kaput after me trying to clean some chemical spray off them using acetone (bad move as I subsequently read!). I decided it was finally time to pull the trigger on a pair of 'getis. Had to decide whether to go for glass (heavier, but the best possible optics) or the new plastic fantastic NXT lenses. The Maestrale driver NXT PhD lenses were on special on Amazon, and with the weak USD, the price was MUCH cheaper than buying locally (as in 1/3rd the price). So, I bought 'em untried and on faith of the good reviews of Serengeti's in general and this model specifically.After a reasonably prompt delivery time (at the beginning of the estimated delivery date), the glasses arrived well packaged. They are very, very light - and the lens quality is excellent visually. I'm glad I went for these over the heavier glass lenses (although of course I don't have them to directly compare with). All i can say is that these NXT lenses are lighter than my old Adidas ones and want for nothing optically. The polarisation and photochromatic properties make them very nice driving lenses - a couple of days ago I was driving directly into bright morning sunshine and the road surface had a very harsh surface glare due to rain that morning. It was very difficult to drive with the naked eye, but the Serengetis cut through it all and made driving easy.With the light weight, I have no problem wearing them for several hours' driving - which hasn't always been the case with other heavier glasses for me. The one minor style caveat of these glasses is that the nose bridge rides quite high up my nose, causing my wife to say "those glasses make your nose look long". Of course YMMV with respect to this!!Highly recommended.These are great polarized glasses, but I need NON-polarized glasses. The description says they are non-polarized, but they definitely are polarized. I kept them because I love the feel and construction, but the search continues for NON polarized.I've ordered two pairs of Serengeti sunglasses from two different suppliers. On receiving them I thought they were non genuine and ask for a return label. I own many other pairs of Serengeti which are more substantial and heavierFortunately the main dealer rang me and explained that instead of Italy, they are now manufacturing in Japan, using materials which are much lighter and although they may appear flimsy they are actually very rugged and have the advantage of feeling very light on the face.He also explained that as well as being polarised the new material has the ability to darken the lense in strong sunlight. The darkening reaction time is 6 minutes, this slower reaction to light makes them ideal for driving.He asked me to try them which I have done and I have to say they are BRILLIANT .In Twilight conditions they take away glare from oncoming traffic headlights while at the same time enhancing my vision of the rest of the road and I love how light and comfortable they are to where.I have as yet not been able to test how they perform in strong sunlight but will be able to test them when I return to Portugal next month.I have cancelled the return labels on both pairsThe only sad thing is that they are no longer available with the reflective gold coating, so not quite as good as they were in the past. Please bring this feature back Serengeti!! It makes them even better.these are SERENGETI MAESTRALE which appeared mis-labelled as Bolle --- absolutely excellent sunglasses especially for driving, brown lenses ,polaroid and photochromic , very light , good construction and excellent Serengeti pedigree, would buy again ESPECIALLY AT THIS PRICE , they are a LOT MORE £ elsewhereniceGreat buy
