    Knox has produced another amazing product! I really like that it can be folded down compactly and put in a carry pouch that comes with the overjacket. I’ve said it in previous product reviews that if you’re thinking whether to make a purchase, don’t think just do. I promise you won’t be disappointed. Every rider must own this piece. I bought this as well as the Walker Waterproof Overtrousers MK2 to wear during wet weather riding, I get to my destinations nice and dry.

    Lovely waterproof motorcycle jacket, exudes usual Knox quality. Compares more to a high end outdoor waterproof than the usual motorcycle over jacket. High collar goes right up to the helmet to prevent a wet neck and water ingress in my helmet. Hood handy when off the bike (not that I’ve got much hair to get wet).

    Only slight issue is sizing is bigger than I expected. Got the same size as my Urbane Pro MK3 and it’s a lot bigger. I guess it’s sized to go over multiple layers.

Core Knox pieces, used for every ride and every season. Start with core protection and add layers to adapt and overcome all conditions, from unbearable heat through to driving rain.


At Knox we have always believed that wearing a close-fitting armoured shirt all year round is always the best way to protect a rider.
