At first use this helmet was great. Super light, padding is very comfortable. I bought it according to their head measurements guide and I needed a large. Less external noise was good. Visors are clear. The transition visor took getting used to especially in darker rainy days. But leaked in heavy rain. Also a pin lock fell out..But after completing a two week ride, the padding has compressed so much that it now fits like an extra large and its like there is no cheek padding and the crown padding is too thin. I spoke with Klim and they won't take it back as its a used helmet. Replacement padding would only be 5mm at best. I ordered my expense. They did offer a discount price to purchase a new medium. At which time I would have to try fitment with thinner padding.. There are some tiny scratches from some huge bugs hitting it, so I can't pretend I didn't use it. Warranty is covering the shield.Because of this I cannot recommend buying one.This was the most expensive helmet I have purchased. I love the finish and the transitions face shield. I also like the wide field of vision. The fit is tight... right on the edge of too tight for my big 3XL noggin' but Bell doesn't seem to have a problem fitting me. I can't speak to the safety and I assume it is great. But the ear pieces do not have depressions for head sets and when I put Cardo's JBL ear phones in they press hard on my ears causing discomfort on long days. Additionally, the inner foam is not designed for any type customization to cure this. The face shield fogs up more than any shield I have owned. (I have 8 helmets currently) and although they include a pinlock, I don't want one on all year long. Last the ventilation is terrible... this is a very hot helmet and a loud one to boot. Will not buy another Klim helmet.Best helmet I’ve ever owned. Love the transition face shield, game changer.Best helmet I’ve owned. The fit is perfect and it’s super comfortable!! Definitely worth every penny!WayneEl casco en si es super liviano y muy sabroso. El visor se comporta muy bien con respecto a la sensibilidad de la luz, pero por las noches cuando hay luces de frente, el pin lock hace un reflejo horrible que debes levantar la visera para poder ver bien. Lo probe sin el pin lock y no hace reflejo. Por eso le di un 4Needed a new helmet for new adv bike and pulled the trigger on this one. The helmet fits perfectly and with all the features that are included a good value. I had a surgery last year on my neck and with the light weight of this helmet has really helped me continue riding. It provides good comfort and cooling even driving in 100+ degree weather her in California. The automatic darkening visor is really nice feature. It is not two loud while driving at freeway speed and the you dont get a lot of head bobble like some helmets i have had. All in all i really enjoy this helmet and the locking system is really nice with gloves on.For starters, this Klim helmet is not near the quality of its competitors. Helmet arrived damaged. Started return 3 weeks ago. Returned helmet 11 days ago. Still no refund. $811 tied up for 3 weeks so far. Pretty disappointed overall.Buen casco, lo encuentro grotezco y grande en la calota
