Kask Rex MTB Helmet - 2016
  • Removable and washable inner padding in Coolmax® material


ECO Chinstrap
  • Chin pad with eco-leather chinstrap
  • The anallergic and washable chinstrap is extremely comfortable and helps to avoid irritation of the skin


M in moulding
  • The innovative “in moulding” technology, joining the inner polystyrene cap to the outer polycarbonate one, ensures a better shock absorption.

  • Inner padding fabric treated with antibacterial and antimicrobial Sanitized® process.
  • Weight - 270g
Mr SHIPLEY Brought to replace a lid by 661, this is a vast improvement in looks, comfort and ventilation.
Mr BURN Looks good, fits great, can hardly feel I've got it on
Mr Scrivens Kask is the best fitting helmet for my head shape and size , would recommend this item
Watson Great helmet sadly it does not fit every shape of head its more for the roundheads than oval heads!
IanR Enduro style helmet that doesn't look too bulky. I find the fit great and like the details such as the leather chin strap.
Yuki Great fit and well adjustable. The build quality is excellent. Highly recommended.
HYDE Well made, extremely comfortable helmet. Excellent service from Merlin, as usual
Mr Evans Love my new Helmet (Kask Rex MTB) - its nice the light and fits just right. This a high quality product, made well and strong. The addition of being able to add a camera or light maybe to useful in the future. I nearly always wear a baseball hat, so its nice to have a peak on my bike helmet, to shade the sun. I mainly ride my mtb cross country and on the road. Comes with a handy bag. It was well packaged, delivered on time and a bargain price! So all good.
Raisanen The large fits my head perfectly. Luckily, tried it on in store before ordering. All my helmets are large, so I would say sizing here is good. Love the leather chin strap and the visor to keep out sun and I wear glasses. Lighter than my previous helmet and more snug (in a reassuring way in that it doesn't jiggle anywhere it shouldn't) fitting. Very good padding inside the helmet. Will be buying Kask again.
Mr Crossley Bought to replace a succession of Giro Hex, which have been my favourite MTB helmets for years. This has just well and truly knocked it off its perch! Absolutely the most comfortable helmet I've worn. Light, airy and great adjustment. The leatherette chin strap is one of those things you never realised you needed until you tried it! Great price and fast service from Merlin as always.
Mr Fern√°ndez Alonso Very comfortable light and cool helmet very adaptable to each person, used these days since it arrived with very hot days and I can say that very well it does not move at all, also we caught a storm and very happy with the visor so that the water does not reach the eyes. Only one catch, the attachment of the stand of the camera seems a bit flimsy and it takes a little time to remove the piece that covers when the camera is not on. But for everything else I am very satisfied with the helmet and would buy again
BOLTON Comfortable and lightweight helmet at a great price, highly recommended
Mr Sugden Superb lightweight helmet. Fits just right. Highly recommended
Rebecca Very comfortable and extremely well fitting helmet. I really like the leather chin strap and smooth motion of the adjustable visor. It even comes with a go pro attachment on the top and goggle clip at the back. Kask helmets are the best fitting helmets I've owned (i've tried Specialized, Bell, Giro and Catlike).
Mr Curtis Excellent fit, comfortable and very stylish, I have two other Kask helmets and others, but they are my first choice anyday. Great customer service from Merlin Cycles as always
Kate I have a small head even in comparison to my other female friends, and the Kask Rex medium still fits me great! Without clipping the chin strap, I can turn my head upside-down and shake it without the Rex sliding off. I am really looking forward to mounting my GoPro to it, and since I ride a fat bike, the goggle strap clasp is a nice touch!
Matt D Great fit, really comfortable and nice and light. Got a great deal too as 2016 model and doesn't hurt that it looks great too. Like the adjustible visor. Merlin were great to deal with. Defintiely recommend. Only thing to consider is that there is no MIPs in this as older model.
childs I love Kask helmets and that is what I use on my road bike. This mtb helmet does not seem to have quite the same quality feel as the top end road helmet, but is still very very good. Better than other mtb helmets that I have tried. Sizing is as stated.
Mr Baker Excellent helmet, very light, adjustable, very comfortable and great value.
Edwards Great fitting / light weight and comfortable helmet with good protection.. Amazing value on sale. Recommended
Rob Great fit and look and very comfortable. Just tested today on a cold ride : light enough for an all-mountain practice. Just one weakness : the lock system is quite low and the branches of my glasses touch it.
gulliver Super light, super comfortable. Really good helmet and got a at an amazing price. Top job merlin!
Alan Cross Fantastic light weight comfy helmet that doesn't get too hot!
