You wear full body armour under the outer skin sir, just like every enduro rider.
I looked at the KTM jacket... bit of a bargain, but I've just bought a Linstrands one with useful pockets and other features I bet the KTM one doesn't. Eg I bet the KTM one isn't waterproof after the first wet ride.
I however didn't get back armour with it. Every cheaper jacket I've had came with full armour inserts yet you have to pay extra for the same armour in the more expensive jackets.
