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.

AGV Diesel Full-Jack Prism Helmet 4 5 2 2
GREAT HELMET Excellent desing an good price for it. A little small but great fit. June 26, 2013
Good take on the K3 This is an AGV K3 with a Diesel paint job. It's a good helmet at an OK price. More expensive than the K3 due to the Diesel tie in, but that is what the wife wanted. Thankfully, it's light due to no useless built in visor (I hate those things). My only gripe is the nose and chin inserts come out too easily, which is a standard deficiency on the K3. Good features, great look. April 29, 2013
