Anything else I had never came close, – too much like american footballer attire. With this one, it’s good and tight too (light and stretchy), so people nearly wouldn’t notice you’re wearing armour.
Has d30 back and shoulders and lightweight foam on the chest. You’d nearly forget you’re wearing it sometimes. Throw on some elbow pads if/when you feel you need them.
The problem with a lot of the other ones is that they’ve bugger all protection for your back. Most other injuries will heal up ok, – but if you mangle your back you’re F-ed.
