Incognito Mode Whether you're sporting the latest race-cut leathers or a casual riding shirt and jeans, pads that make you look like coach is about to put you in at the end of the 4th quarter are a no-go. AXIAL's AX2 Air lineup trims the bulk from their popular AX2, making it thinner, lighter and more breathable - all while offering the same CE Level 2 safety rating to add some protection to your gearset. Ditch your bulky armor for this ultra-flexible alternative or add a layer of comfortable protection to your jacket or pants with the AXIAL AX2 Air Elbow/Knee Armor. The Coolest Kid On The Block One of the common complaints about modern CE Level 2 armor, aside from the size and thickness, is that they just don't breathe enough air to be comfortable in warmer weather. Without the extra bulk of traditional armor, you'll be looking cool - and more importantly, feeling cooler. The highly ventilated proprietary design of the AX2 Air armor helps to dissipate heat like no other. By allowing heat to escape at a standstill while intaking cool air as you cruise the streets, you'll be more comfortable than ever all while increasing the safety level of your favorite riding gear.
