Kask Protone Road Cycling Helmet

The Kask Protone helmet provides the perfect blend of aerodynamic performance, low weight, maximum ventilation and amazingly stylish looks. Kask’s top of the range road helmet developed in partnership with Team Sky has been proven in the toughest pro-cycling races around the world.

Weighing just 230 grams the Protone is not only lightweight but incredibly aerodynamic too. It was developed using extensive wind-tunnel testing beyond typical testing boundaries, with Kask continuing to modify the profile of the helmet until it performed excellently with the head in any position. 

 

Features

Produced using their innovative ‘In-Moulding’ system the Kask Protone helmet features a fully adjustable floating cradle and internal gel pads which together provide a close, comfortable fit. The Kask’s notable up and down adjustment system means it is one of the most precise fitting helmets out there thanks to its unique double pivot design. With an eco-leather chinstrap which is anallergic & washable helping to avoid skin irritation, a rubberised Micro Dial adjuster on the back of the helmet and a floating cradle with internal gel pads for the Kask Protone features Coolmax inner padding treated with an antibacterial and antimicrobial process to help keep the helmet fresh and odour free.

Mr Bond Great fit and super light so you hardly notice you're wearing. would recommend
DAR Nice fitting helmet, certainly an upgrade on my previous helmet. Expensive but so is your head!!
Mr DIAZ Servicio de entrega muy rápido. El casco se ajusta a la perfecciòn, sin duda un caso de mucha calidad. Para un contorno de 58 cm compré talla M y me queda perfecta,
Mr Naumiuk Upgraded from Kask Mojito after small crash and little hit on the pavement. Proton fits perfectly and feels so much lighter. Good venting and comfort. Recommending this item.
Mr Guohui Love it. Great fit and the strap is superbly designed. Easy to clean.
Jon This will be my third Kask Protone helmet having had the misfortune to have been involved in 2 high speed crashes where they protected me from a serious head injury or potentially worse. They are not cheap but it’s a small price to pay...
Andrew As expected. Much more compact than my previous Giro Aiglis. Decided to go with L rather than M (I was in between sizes). This was the right choice. M felt like it sat on top of my head as opposed to over my head.
David I’ve tried several helmets over the past few weeks and this is by far the best, and the one I will end up keeping, good adjustability and sits right, although admittedly is is the most expensive
CB Nice and light but I couldn’t get a good fit on this unfortunately so I’ve now got a Giro Aether MIPS (from Merlin, it’s brilliant) instead.
Mr francart Fantastic helmet so light . I use it to race mainly and unlike other helmets I have there isn’t much sweat on the pads as the helmet is so well ventilated. Quick delivery from merlin as always
Mr Irvine Great product and fits really well. Good quality with a nice smooth comfortable leather chin strap..
Mr Wolfe This helmet is light, extremely comfortable and cool on hot days. It is very stable on your head. Overall the best helmet I have used
Mr Booth Fantastic buy, Very comfortable and love the attention to detail.
Mrs Chalmers Excellent helmet. Very light. The only downside is that there is no adjustment in the v-straps that come down over your ears .
Mr Jones This is my 4th kask helmet I’ve purchased over the years. Excellent quality and typical fast delivery from Merlin
Nick Bought as a replacement for an old Giro helmet. I have a Kask MTB helmet that is by far and away the most comfortable I've ever used, so seemed sensible to go for the same brand. Only used a couple of times so far but it's great. The fit is spot on, its light as a feather and even reasonably stylish (for a cycle helmet!).
Mr Shaw Been looking for a suitable lid for a while. Tried a few different ones on but when it came to the Protone, it fitted like a glove straight away so for me comfort won over cost. Saved a few pounds getting it from merlin cycles, win win for me
Mr Andrews Really please with this purchase. Have used it a couple of times now and it feels very light but secure. In fact it feels as though I'm not wearing it, if that makes sense! Love the security, of it and the brilliant construction. Merlin cycles sold it for a good price too!!
Rei QIU Very good, this is one of the best helmets I owned. Very comfortable.
Cloke Really great product. Have used in 35 degrees on climbs and not too hot. Also sound of air rushing past ears is quieter than other helmets I've used which was a pleasant surprise. Merlin offered a very competitive price with great service again.
Mr Pijanowski This is one of the best helmets I owned. Very comfortable. My Giro Aeon cracked after crash and replaced with Kask Protone.
Walter The most comfortable helmet amongst other brands, good looking and easy to fit. A little bit heavier than others, but i still recommend this product.
Mr Rea It's surprisingly more airy than my Giro Aeon, even stationary. It's different as it sits low around the forehead which probably provides better protection and has a vey low profile (no mushroom head). Though she's not cheap it's still the best helmet I've had.
Chris Browne Love this helmet. Fits great, superb quality and attention to detail in the Design, plus it performs superbly. Airflow through the helmet is good, but still feels aero, with the wind breezing smoothly on windy days. Super quick and efficient delivery from Merlin - nice!
