Julbo Aerolite Performance Sunglasses with REACTIV or Spectron Lens - Lightweight Polarized Sports Eyewear for Running, Cycling & Outdoor Adventures

I know these are supposed to be lightweight but for over $200 I'd expect something more sturdy. I bought them for a climb of Rainier and they should be OK for that. As long as I don't drop them. They do get pretty dark, I tried them in the snow at around 10,000 feet and the light intensity was comfortable. But they are really flimsy. Also the nose clips are supposed to be adjustable but I could not find a position that was very comfortable. They don't fog, which was my main criteria, since other Julbo sunglasses I have bought fogged terribly. So the photochromic lenses work OK and they don't fog, I just wish they didn't feel like they were about to fall apart.Very happy with the reactiv lens. I bought these primarily to mountain bike in and am really happy with them going between bright open spaces and then into the darker woods. They are not so dark that they impair your vision and are just dark enough to take the sting out of a bright cloudless sunny day. They also stay on my face and don't slide around like other similar styles. I have a small face and took a chance on these and am happy with them.The lens didnt get dark enough for bright Colorado sun. Left me squinting. Too bad because the fit was great.Ok, this is my first review, but I have been looking for the perfect sunglasses for 3-4 years and I’ve found them. I just finished a hard intervals based bike and run. These are so lightweight and the flexibility/grip so good that they don’t move. And I forgot I even had them on. The optics and photochromatic capability are great too. These replace a pair of lightweight Uvex sunglasses that I’ve had for 12 years. I wish I could spend a little less, but I plan to use these for 10+ years and get my money’s worth.The julbo aerolite are pricey for what you get. The innermost side of the lenses has a coating that gets dirty quickly and the coating is hard to clean. The air coming around the lenses does cause some blurry vision and the frames will slide down my nose when I’m working hard and sweating. I wish the silk sack didn’t have Jublo marketing on the outside because it makes it hard to use the sack as a cleaning cloth and the semi hard outer case has me worried that the glasses will get crushed when I put them in my backpack. The glasses have a fragile look and feel to them.That said they are very lite and the shading is nice. I assume they are made for pro/elite sports athletes which I am not.Before I bought this product, I did a lot of research...I read many great feedback about this product especially from athletes (runners, hikers, etc). Which led me to purchase it..Now that I have it, I’m beginning to wonder if those consumer reviews were real or paid robots by advertisers..I think it’s a little pricey for something that feels / looks really “cheap”. I could’ve gone to Big 5 and picked up one of those $50 sunglasses, (also made in Taiwan) which serve the same purpose. I’m debating whether I should return this item or not.CyclingClear anti-fog, photochromatic lens. They do fit women's faces, and work perfectly on the trails. I do wish they were just a smidgen tighter because when I have my head inverted (hiking a football in the co-ed flag football league), they slide down my nose.I've found these glasses don't fit particularly well on my head. It says they are suited to female or Asian heads, but mine must be particularly tiny because they are just far too bouncy. They seem to be OK on completely flat roads, but as soon as I get on trails, particularly downhill ones, I'm constantly having to push them up on my nose, which isn't what you want to be doing when you're trying to concentrate on not landing flat on your face. The nose grip is not bad I suppose, but the arms just seem to offer no grip whatsoever, and I end up with a sort of tension headache from trying to keep them in place by scrunching my nose up. The photochromic technology seems to work well, but I can see me only wanting to wear them for road running which is exactly where you don't need it - you want it for when you're weaving in and out of trees in a wood.Die Julbo Damen Aerolite mit "Zebra Light Red"-Gläsern ist eine Klasse Brille, perfekte Anpassung an alle Nasenformen möglich, super leicht, man spürt sie nicht, chic! Die photochromen(reactiv) Julbo-Gläser sind sowieso Spitze. Wollte die "Zebra Light Red"-Gläser in einer sehr gut belüfteten Brille für Radeln, Skilanglauf, Klettern. Die Aerolite ist optisch sehr chic für schmalere Frauengesichter und sitzt auch gut. Wegen meiner langen Wimpern kann ich sie aber leider nicht nah genug an die Augen schieben, um den Lichteinfall von oben zu minimieren. Deshalb hab ich mich mit einem Wehmutstropfen letztendlich für die Aero (auch mit "Zebra Light Red"-Gläsern) entschieden, die durch den vorhandenen oberen Rahmen das Licht besser abschirmt. Die Aero ist auch eine tolle Brille, aber breiter und für Männergesichter gemacht. Die gefühlte Passform ist genauso toll wie bei der Aerolite, sitzt auch auf meinem eher schmalen Kopf sicher, komfortabel, leicht; nur für Frauen hinsichtlich der "Schönheit" nicht ganz so chic wie die Aerolite (für Männer jedoch top!). Aber bei wichtigen Ausrüstungsgegenständen rangiert bei mir die Funktionalität vor der Schönheit.Fazit: Volle Punktzahl für beide Brillen und insbesondere für die Gläser die mit einem Lichtdurchlässigkeitsfaktor von 13<>72% von Radeln bei Dämmerung bis Skilanglauf beste Sicht ermöglichen!Geniales para caras finas, súper ligeras y comodísimas, no pesan nada.La claridad con las gafas puestas es espectacular, y el cambio gradual con zonas menos luminosas muy bueno.Es la 1a vez que tengo unas gafas tan pro.El único pero que le pondría es que los cristales no se vuelven totalmente oscuros y se ven los ojos levemente, pero tiene unos reflejos guapísimos que hacen que se disimulen bastante.Para días nublados o seminublados son una pasada, claridad máxima.Muy contenta con la compra.son caras, sí, pero merecen cada euro, las fotocromáticas se adaptan super bien, nosotros para bici nos van perfectas. y para montaña también, aunque las cogería más oscuras para altura y nieve.Llevo ya unos meses con ellas y es verdad que resisten bien a la grasa en el cristal, super ligeras y no se mueven una gota con los insertos de goma. en cuanto a ventilación,casi nunca se me han empañado.Leggeri, non scivolano e si prestano bene a varie attività (sia corsa che ciclismo). Belli anche i colori. Arrivano con solo la custodia morbida. Unica pecca, un po’ cari.
