AGV Diesel Full-Jack Prism Helmet

The Full-Jack is an integral helmet in the Diesel line made by AGV. Based on the K-3, one of the absolute best sellers in the AGV range, the Full-Jack maintains all its  technical features and combines them with the Diesel’s creative originality. The exterior  shell is made of HIR-TH (High Resistant Thermoplastic Resin), and is available in sizes  from XS to XXL. Fresh air flows into the helmet thanks to air intakes on the front and chin guard while 2 side extractors and a rear extractor incorporated in the spoiler remove hot, moist air from the helmet.

The faceshield, is scratch-proof and anti-fog, and provides 100% protection against UV rays. The removable and washable inner liners are in Dri-Lex with sanitizing treatment, which prevents both bacteria from forming and allergies. This fabric helps to quickly remove moisture from the skin, absorb excessive perspiration and ensure freshness also in the long term. The visor mechanism with its XQRS (Extra Quick Release System) is not only lightweight and functional but also has an innovative PVS (Perimetrical Visor Seal) system. The edge of the visor is coupled with the  visor profile along the entire perimeter length, including the sides, thanks to specific  housing on the mechanism.

The monochrome versions of the  Full-Jack have a bright yellow visor mechanism, which recalls the technical details of  sports cars and motorbikes and matches the Diesel logo on the side. The end of the strap is personalised with the Diesel Mohican symbol, also in yellow. 

Included with the Diesel Full-Jack helmet is a printed canvass shoulder bag / helmet bag.

excellent style, bang for your buck! This helmet was a gift for my gf, I bought the white one. So far no complaints, she loves it. I think was excellent. But choose a size larger, its a little narrow. May 4, 2015
It's an okay helmet The best thing about this helmet is the looks. Not very comfortable. Wobbles at 70+ mph. Let's in cold air from the chin area . Very noisy and not easy to remove after the ride. I will buy an other one soon. It also runs small. I bought an XL after measuring but it was too tight. So had to upgrade to an XXL. April 27, 2015
Great helmet Recently purchased this helmet and I am very happy with it. Its a solid helmet with a nice design and a wide view which I liked. April 19, 2015
Precisely what I wanted I was looking for a unique and subtly custom looking helmet and this fits the bill. I have had Scorpion helmets exclusively and this has a bit more space and is very comfortable & light. I love the colored hinges of the visor. Very nice shape and design. This is my first AGV helmet and yet to log many miles but so far I love it. Fit and finish are high level for the price. April 8, 2015
Best bang for the buck This is one of the best looking helmets I've ever purchased. It's so stylish and very comfortable. I've been using it for commute daily and I've had no issues whatsoever. The helmet is fairly light. I particularly am in love with it's styling. I had to exchange the helmet once because it felt a little too tight when I ordered it by the sizing chart (after measuring my head). The one I have now fits perfectly. The air flow is very good and it's not too loud. The only annoyance is the occasional fogging which can be taken care of with an anti fogger or a better visor. I would definitely recommend this helmet. March 14, 2015
A quality purchase!!! The moment i picked up the box i was very surprised about how light weight the helmet was. The helmet fits perfectly with the K3 design mold. Other helmets that I've tried tended to press too hardly against the back of my jaw causing major discomfort, this helmet however hugs in all the right places. The vision is fairly wide and accomodates my glasses as well. In all honesty the motivation behind the selection of this particular helmet was the minimal design styling it featured. after wearing it and having it in my possession for a bit though i am extremely satisfied with the premium features of the piece.

Great helmet I wanted a cool helmet with minimal branding, and this helmet definitely fits the bill. I haven't had it very long, so it hasn't been through any extreme conditions (ie, heavy rain, blistering heat, etc) but so far it works wonderfully. I bought the medium sized helmet for my medium sized head and it fits nicely. A little snug at first, but after breaking it in a bit it fits perfectly. There's venting on the forehead and in front of the mouth and when they're open I can feel a whole lot of airflow. I'm confident this helmet will be comfortable even during the hot summers here in Florida. Just a good helmet overall, and one that's not outrageously expensive. December 17, 2014
An Awesome Helmet For The Beginners This AGV helmet is awesome.The design looks stylish,it looks great from a distance and it definitely worth spending.It gives a fitting feel and the noise level from my bike is not really a problem.Im using KTM RC200 with stock exhaust at the moment,so those using that bike might want to try this helmet as it suits well with the bike looks.The airflow features works as what it was told and its great.Great product for me.
