Hey whats up guys its Ruben at competiton accessories here checking out the HJC RPHA X offroad helmet. This is really the first premium offroadhelmet weve seen from HJC, they have taken alot from what they have learned from there moto GP top of the line RPS10 street helmet and they broughtit over and developed a very impressive off road helmet. Ive done quite a bit of off road riding and ive ridin in quite a few different brands ofoff road helmets and this is right up to par with all the other premium helmets on there. First things first is its very light weight which is goingto reduce neck fatiuqe which will help you be more competitive. It comes in at 2.92 pounds for the medium and large size model, which is very lightweight. The shell itself is constructed with premium integrated matrix design which incorporates carbon fiber aramid fibers and fiberglass, which creates a very ridgid strong shell. Basically if you go down and hit say a rock its going to spread the impact over the largest area possible, an then the eps foam inside the helmet is designed to slow your head down gently so that you dont get any brain injuries. If you just take a look at the aggressive designof the shell shape. Its going to be extremely aerodynamic and you do have an adjustable visor piece so that you can adjust this up and down dependingon the conditions, so if your in a real muddy race you can adjust this nice and low. Also its got good coverage on it if you wont a little more ventilationyou can raise it up obviously its removable and replaceable as well. Very aggresive ventilation vents as well in the past they've called it thereadvanced channeling ventilation system and this is something they've brought over from there road race helmets, but if you look at the front of thistheres air intakes on the mouth guard. Here you have intakes right along the top of the brow thats going to bring air right around the top of your googlesand theres channels that we'll look at in a minute that go up inside underneath the visor peak which might be hard to see. There are actually small ventsas well those are going to function almost like ram air scoops. Air is going to be channeled in underneath this visor peak and be forced down insidethe vents on the helmet, there are more vents at the top of the shell here bringing in more air and then at the back you have some exhaust vents. Exhaustingwarm air out of the helmet is one of the best ways to get hot air out and keep you comfortable as you ride. Low pressures kind of generate in behind thehelmet here and that kind of draws the warm air right out the back of the helmet. Inside the helmet you have what they call there cool forever fabricthis is an advanced new fabric it has ginkgo extract in the fibers. Its designed specifically to moisture wick but also not get hot so those hot ridesyou know typically even if its not really hot outside alot of times your working hard when your riding off road so your sweating alot, and this is goingto do a really good job managing all that moisture and keeping you cool as you ride. You can remove the interior as well so for cleaning up the cheek padsand the rest of the helmet your going to be able to pull the inside out. Theres basically three snaps and a tab around the side of the cheek pad so youcan see it is a nice contoured cheek pad design on the inside there, and then you can also remove the crown liner couple snaps at the back and thenaround the front of the crown. When they do it this way you have some tabs around the crown that prevents any snaps, velcro in this area from being right onyour forehead so it attaches out in front of the shell itself so its not creating any pressure points. It is a nice open design so you will see that thereis plenty of ventilation so its going to get right through to your skin to keep you more comfortable. Look at the inside here you do have air channelsbuilt in and you'll see that theres plenty of holes in there so that all that air flow can come in and breathe through out the whole helmet and keepyou comfortable for those long hot motos. RPHA X retails at around the 350 dollar market a little more for some of the graphics and around that mark forthe solids. So you can check those out online on our website at competitionaccessories.com and see what our current pricing is. Very impressive helmetvery light very well thought out very well engineered and a nice design. Also there are different graphics available as well as solids you can checkthose out online.

    Beautiful Helmet - Big-D   AZ Recommended by Reviewer: Yes
    Pros: Color Scheme is awesome, extremely light weight, very comfortable, allows for perfect fit and visability
    Cons: Sizes run Small

    I first purchased this helmet in a Large. I have several other helmets in various brands and they are all in Large and fit very nicely. However, this helmet in a Large was way too tight, so much so I bought another in a X-Large. Now it fits perfect so I can wear this helmet for really long period with no pain or discomfort from it being too tight. And it is not too big either, the fit is perfect.I would have rated this helmet a 5-Star except because I had worn the first helmet in Large, I was not able to return it and had to purchase a second in XL. Ultimately costing me twice as much. However, I like this helmet so much, it was worth it to me to make the double purchase. The other helmet in Large I gave it to a very good friend that it fit just right.The construction of this helmet meets or exceeds the much higher priced helmets in the 600 price range

    Beautiful Helmet - Big-D   AZ Recommended by Reviewer: Yes
    Pros: Super Light Weight, Great Graphics, Superb Construction, Comfortable once on
    Cons: Size runs a little small, really right putting over head.

    Although my helmet size has always run border line between a Large & Extra-Large, it seems every helmet I have ever bought, the large has always fit just right the way a helmet should fit, while I have bought two helmets in Extra-Large only to have them move around too much, being told they were too big for me.After receiving this HJC RPHA-X Factor helmet in Large, I couldn't wait to slip it on. When first putting it on, it almost wouldn't go over my head. Realizing its new and may need to adjust to my head shape, I forced it over my head. Once on, it fit snug, but comfortable. It doesn't feel overly tight, nor do I think it will make my head sore. The only problem at this point is the initial fitting over my head. It seems the opening is really tight, almost as though it has the opening on a Medium and the shell is a large.I will try it for several rides and see how it feels once broke in. I love the helmet. It is one of the finest looking helmets I've ever owned and I have 11 helmets from several manufacturers.

    The sizing information is provided by the manufacturer and does not guarantee a perfect fit. However, we are happy to assist you with any needed exchanges.

    Note: the RPHA-Max seems to run a little smaller due to the thick padding and smaller overall shell design. Most size exchanges have been to up a size. So if you are on the fence. We recommend thinking about going up a size to start. However, please keep in mind the padding will break in some and a helmet that is a little tight vs. too loose for safety.
