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.

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
Cost-effective product Amazing helmet, really light but sturdy. Vision through the helmet is really well.. The price is of the helmet you can't beat considering the quality you're receiving. I bought a mirrored faceshield (AGV k3/k4 Evo) to add a nice touch. Definitely recommend this product.. March 17, 2014
Small Fit The helmet is great, the visor is unique also bought the smoke visor and it is just great the only problem is that the helmet squeezes the ears, on long trips it will hurt them and need to make a stop and take off the helmet. need more space for them. besides that, is the greatest helmet I have ever had!!! March 13, 2014
Great first full helmet! I'm new to street biking, but the comfort, fit, style, and simplicity of this helmet are exactly what I hoped for. I have been blown away at how easy and thorough Revzilla is to work with. One of the best purchasing experiences I have had. October 28, 2013
