HJC IS 33 Review

by - verified purchaser
I had borrowed my brother's HJC IS 33 and really liked all the features and was going to order one and then I saw the HJCFG Jet High Visibility Helmet and decided to purchase it. However be advised the "Jet" helmets run about 1/2 size smaller than the IS-33. Had to send the "Jet" helmet back, and purchase my original choice because they do not make a 3X size and I must say that I'm very pleased with the HJC IS-33.

Good Price & Good Company

by - verified purchaser
I had been looking for a new helmet & came across Jafrum's web site & they were advertising the HJC IS-33 as a close out special. Received it in 3 business days & upon receiving I went for a ride just to see how it felt. It was great a very good comfortable helmet, I have now since then installed my Bluetooth & it worked very well with the helmet. Good price & good company to buy from.

Excellent Helmet HJC IS33

by - verified purchaser
This was a very good price on an excellent helmet. I like that it has a clear full visor that really keeps the wind off your face but also has the smaller sunshade visor that's easy to put down & retract even with the clear visor down. The first time I lowered the sunshade visor, it pressed against my nose (fairly large nose). Fortunately, there is a stop position just above that which solved the issue.

Great helmet and awesome service!

by - verified purchaser
Read the reviews and watched the video about this helmet and its ability to keep the head cool, which is a must for Texas in the Summer (or any season). I followed the size chart and ordered the recommended Large. When the helmet arrived it was a VERY tight fit and after several minutes of waring it, I began to have a head ache. I reached out to the customer service via chat and was emailed the return form and sent it back. In less than a week I had my new LX helmet and I haven't gone a day without wearing it. The helmet is a 5 star and Jafrum's service is a 10+.

A Fantastic Product, HJC IS33

Moving to a hot sunny climate and this was the perfect helmet with the superior venting and open face shield + flip up/down option on sunshield. A well designed product that I wish I had found earlier. Will be purchasing one for my lady upon arrival destination.@ Myrtle Beach SC August. ! Excellent color selections. My neighbor is also a happy owner who travels extensively in Eastern US.. Thank You

HJC IS-33 Helmet Review

This is my third HJC helmet and the best by far. I especially like the flexibility of the wind screen and sun shade. I do a lot of open-road riding and those features make those trips a lot more comfortable.

HJC IS33 Solid Helmet Review

by - verified purchaser
Let me start by saying the return policy and service at Jafram is awesome and better then most sites I have used . I would say, equal to that of Amazon in my humble opinion. As for the helmet, the size chart suggested a L and it was too small but now that I have received my XL I couldn't be happier. Much quieter then my 1/2 helmet and the wind screen and integrated sun shield are nice and distortion free. The air-flow is plentiful and keeps my head cool. Worth every penny.

Great Helmet

My measurement was right at the high end of medium, so I went with a large. The fit is just right. This is the best open face helmet I've owned. Sun shade works great and you never realize you're looking thru a visor.

HJC IS-33 Helmet Review

by - verified purchaser
I googled how to size a helmet and came across a Jafrum video. It was exactly what I was looking for to help me order a new helmet. I then went to the Jafrum web site to shop and found the HJC IS-33 Helmet and for a great price. I ordered it, got it a few days later and it fit perfectly. This is a comfortable and light weight helmet. Very happy with my purchase.

HJC Helmet IS 33

This is a great helmet especially with the sunglass insert . I would suggest that you get a size larger than usual because it fits tightly. Order came quickly as has other merchandise I have ordered from Jafrum.

Better Than I Expected

by - verified purchaser
I got the helmet 3 days after ordering. Tried it on and it seemed a little tight. I got the next size up as advised. Took a 1 hour ride to try it out. Kept my head cool and both visors worked great. I like the fact that it cut out most all wind noise up to 55 or 60 and still didn't have much, but I could hear my bike. I ride a Harley Dyna Super Glide Custom with windshield. After the ride it seemed the helmet had fit to my head. Couple more rides and it isn't tight anymore, just fits good. Great helmet.

HJC IS -33 Helmet

by - verified purchaser
I'm a female, 2013 CVO Road Glide rider and this is my second helmet that I've purchased. I had my other one for 3 years and had to replace it due to dropping it/scuffing it up. I LOVE this helmet!! You can replace the shield if you like which is an awesome feature. I wear a medium and it fits perfectly. I have a Harley helmet that is a 1/2 helmet with a visor included and it doesn't even compare to this awesome one! Buy with confidence! My Favorite Helmet!!

Great Helmet at this price point.

by - verified purchaser
Purchased 2 of these for the wife and I, and installed Scala intercom purchased from Jafrum for these helmets. Fit and finish are excellent, although I find size to be a bit snug. Likely it will conform after more use. Sun visor is nice, but a light shade. Airflow is great through the vents.

The IS-33 is one of four open face offerings currently available from HJC. It sits second in the pecking order behind the FG-Jet and in front of the CS-5N and the CL-33. The main difference between the FG-Jet and this IS-33 is the shell material. The IS-33 has a polycarbonate shell. It is very high quality, but doesn't have quite the impact absorption, or the ultra-light weight of the FG's fiberglass composite shell. The IS-33 is still very lightweight, though, weighing in right at three point two pounds.

The IS-33 has a similar polycarb shell material as the CL-33, but the CL-33 has simpler ventilation, and lacks the interior sunshade. The CS-5N is the value priced open face model with a thermoplastic alloy shell and intake only ventilation.

The IS-33 is available in six solid colors and numerous graphics and the paint quality is very good. Most helmets in this price point will have tiny bits of trash or imperfections in the paint, but these 33's look sharp.

It's available in sizes extra small thru double extra-large, and, like the IS MAX, I found the fit to be a little on the snug side. I have a twenty three and a half inch nugget, and the fitment chart suggests a large. This large fits a little bit too snug, though, although I do have a long oval head shape. I think this helmet will work best on someone with a more intermediate oval head form.

Let's take a look at some of the features. The IS-33 sports some pretty decent ventilation. The ACS, or Advanced Channeling Ventilation System works very well to introduce cool air into the front of the helmet, then extract hot, moist air out the back. This ventilation can be credited to two things. First, the helmet's shell is cad designed, so the placement and shape of the vents is optimized. Second is the multi piece, multi density EPS liner. The channels in this liner help to funnel air all the way through the helmet, from these adjustable crown vents all the way back to these Venturi's.

While we are looking at the EPS, we can also see the IS-33's Silver Cool liner. This is one of my favorite helmet liner systems. The wicking fabric is very soft and the padding is plush; it's definitely a helmet that is going to be comfortable all day. The liner also has vent holes which flow air directly to your head and assist in keeping the liner dry in hot weather.

The cheek pads are equipped with speaker pockets for adding a communication system, and the rear tab has been replaced with a patch of Velcro to make speaker adjustments very easy.

The feature on this 33 that surprised me the most was the shield system. In addition to the wide peripheral view and the clarity, the shield works really well with the eye port gasket to quiet road and wind noise. The baseplate system also works very well. To remove the shield, just press this lever toward the rear of the helmet and pull out on the rear edge of the shield. Just press the shield against the baseplate to reinstall.

The final feature in this IS-33 overview is the three stage, one touch, integrated sunshield. This system is almost perfect. The lever is easy to find with a gloved hand, and the shield comes down far enough that you're not looking at the bottom edge of the sunshield while you ride. If the sunshield doesn't come down far enough, your eyes are constantly refocusing and you end up with a headache. The only negative to this system is that the spring loaded mechanism isn't throttled when you release it, so if you don't guide the lever back, the sound in the helmet is extremely loud when the lever bangs against the bottom of the channel. The mechanism on the FG is throttled, and what a difference.

what blue tooth works best with the HJC IS-33 Helmet?
A shopper on Apr 24, 2015
Best Answer:This helmet doesn't work well with a Bluetooth. The open face creates lots of wind noise. It makes it impossible to communicate. My advice is if u want to actually use ur Bluetooth get a full face helmet. We have a pair and wish we would have gotten the full face version

Can a visor be installed on this helmet?
Justin S on May 10, 2015
Best Answer:Yes, there a face shield and a sun shield that both come with this helmet and can be replaced. Each part can be purchased on the Jafrum site as needed. My helemt is about 6 months old and so I have not personally needed to change these shields yet.

A shopper on Nov 10, 2014
Best Answer:Bob I don't know I have a full face I don't wear.Just not into them. I can tell you if the helmet fits correctly you have all day comfort. The face shield does good bug and weather protection just doesn't protect face and jaw if you face plant it on the road.

do you carry an inner dark smoke sunshield for an HJC33ll helmet (not the same fitment as for an older HJC33) ?
