Cranial protection is the number one feature we look for in a helmet. Safety certifications keep our minds at ease, and features like ventilation and helmet adjustment become the deciding factors. The Kask K.50 EVO earns high marks in our book for being good looking and comfortable, without sacrificing its number one duty—safety. The Italian-made K.50 Evo uses Kask's Up-N-Down adjustment system for provide a perfect fit, and 24 vents throughout the helmet keep air flowing over your head.

Helmet fit is is the one thing you'll notice every time you ride. And, if you're like us, you ride a lot, and have plenty of time to notice when things aren't quite right. Kask used its signature Up-N-Down adjustment system in the K.50 Evo. This system adjusts around and cradles the back of your head to fit the helmet to the two planes of your head, instead of a single adjustment to the circumference. 

The inner shell of the helmet is made of compressed polystyrene with an in-molded frame. Kask uses an in-mold construction method to combine the polycarbonate shell and the polystyrene inner, which makes for better shock absorption. The strengthened inner frame of the K.50 Evo also serves to keep the entire helmet from breaking into pieces if you do happen to hit the pavement.

The K.50 Evo is equipped with 24 vents throughout the front, sides, and rear to let air flow freely. Although you may not need that much ventilation in the winter, a thin balaclava will fit nicely under the helmet on chilly days.

The hypo-allergenic and washable Coolmax chinstrap won't irritate your skin. You'll find CoolMax in the  removable and washable inner padding, as well. The helmet connects with nylon thermo fixed straps and a quick release buckle.

The Kask K.50 Evo comes only in White with black straps and is available in two sizes, Medium and Large.

good fit, heavy, weird vents

  • Familiarity: I've put it through the wringer

2000 miles with this helmet. positives are:

sizing seems right. i have a 58cm sized head; medium fits perfectly.

the harness that wraps around the back of the head. the ratchet dial is easy to use, secure, and well-made. the harness itself is designed to tilt above the ear for a more secure and comfortable fit. it's one of the best fitting helmets i've owned.

the bad-- it's slightly on the heavier side for those that care. the biggest issue was not being able to slide my glasses into the vents above the temples. the vents are too small and too narrow.

Great helmet

  • Familiarity: I've used it several times

I like the dual adjust-ability. Makes for a very comfortable fit. I can't even tell I'm wearing it. The sizing was right on the money and the ventilation is also great.

If you're in the middle, size up.

    So the sizing chart splits at 23 inches, and when I measured my head it was exactly 23. I ordered the medium first, and it was definitely too small, but the large came a few days ago and I love it. It ventilates perfectly when I ride, fits snugly, and is light and comfortable not to notice on 20+ mile rides. Would recommend to a friend.

    As described!

      Received my helmet today and is true to the sizing chart. Easily adjustable, nice soft chin strap and a sleek looking design. Can't beat this sale price. Feels nice and comfortable, but I've yet to ride with it. If there's questions I will write back again after some KM's are put on it.
