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.

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.

Great Product I love the look. Comfortable on my head and is light. I love this helmet. Exactly what I was looking for. October 27, 2014
Great looking helmet. Top brand for a reasonable price I would highly recommend this helmet to anyone. I've had several complements on how it looks. I put a smoked screen on it as well, pairs with the matte green helmet perfectly. Fits pretty snug until it breaks in. July 14, 2014
Great fit, but awkward around the ears. The quality on this helmet is quite good. Comfort is great but when I wore the helmet for an extended time my right ear began to hurt. might just be my head but it is still a problem. Otherwise great helmet. July 14, 2014
Great helmet looks very stylish Great helmet looks very stylish and great air flow but little too loud and narrow. Got few compliments on the helmet, I ride Red Ducati so helmet matches with my bike perfectly. Not good for long rides as it gets loud. July 7, 2014
Great but snug This is a great helmet, light and balanced. I ride a red 2008 Ducati monster s2r 1000 and the red helmet matches perfectly. However, the helmet runs a size too small. I've owned 3 medium AGVs in the past and ordered a medium, but it's way too snug. I don't think I will give it time to break-in, because that's leaving too much for chance. I also wear glasses, and there is no room at all to squeeze in glasses over you ears. I will be returning this for a large. June 10, 2014
