Fit well and make me feel safe.

Stop thinking about it and order this one. Sizing; If you're a normal size and want this as your summer jacket, go for your normal size. If you're big, want layers under it or both, maybe size up. Armour is great and even with chest plate in the ventilation is good.

Nice piece of kit!

I think the Knox Zephyr Pro jacket offers a unique and excellent combination of protection and comfort. Knox armor is top of the line and the jacket itself has excellent materials and construction. The jacket is form-fitting and - in my opinion - looks great on.

Beautifully Made

A beautifully made, high quality material, summer riding jacket. The mesh material on the arms and torso allow for great cooling in hot weather. 6-pieces of separate armour included (shoulders, elbows, back and chest protection) at CE-Level 2 rating makes this a more protective jacket than even my big bulky Alpinestars winter jacket. WARNING: This jacket's sizing comes up extremely small. I usually wear a size small in most jackets/shirts etc. I bought a medium in the Zephyr Pro, but I should have gone for a large. I only hope now that the material gives a little over time as it is a very tight fit. Hence the 4-stars. Due to a lack of stock at SBS in the other sizes, I couldn't return and try the L unfortunately before the returns period was over. I'd advise buying two jackets 1 and 2 sizes bigger than your normal, trying them and keeping the better fitting size.
