Back protector?

[steve_t]

Knox Aegis transmits less than 6kN in the CE test, gives better scapula protection and is not 2 inches thick.
Doesn't it make sense that armour have an energy absorbing body of material that's covered by a more rigid shell? Eg helmets.

Yeah but helmets are designed to crack (resulting in their throw away recomendations post crash) , the average Knox armour is clearly not designed to disperse energy by breaking/fracturing as it's built like a brick shithouse

I thought most of the protection of a helmet came from the lining material compressing. Polystyrene only compresses once so after an impact, it no longer protects as well.
Actually, thinking about back protectors, I would think that given the same thickness of the soft stuff, the harder shell would help spread the force over a larger area and reduce the transmitted force. I'd be interested to see what would happen to the Sub4 if it had a thin hard shell on the outside of it's 2 inches of Nitrex. Not sure how people fit that under their leathers comfortably

I was under the impression the hard outer of the helmet is to prevent penetration ?

I have read some material, where softer plastic shelled helmets actually transmitted less energy to the head inside (than stiff shell), as the shell absorbed some of the impact through it deforming..

Off topic I know, but $$$ helmet does not necessarily mean better protection. Wish I had of read more BEFORE I spent $800 on a helmet.

Anyone have any comments on the Alpinestars Bionic back protector?

I use one, find it very comfy fits snugly and normal Alpine Stars high quality.

Yup! VERY comfy!
At this stage I've worn mine lots, just not tried it for it's intended purpose.
Alpinestars is good stuff!

CE level 2 protection, and the extra bits aswell for $250. (on special from $400)

Any opinions? apparently the back protector can be removed (according to a video review ive seen).

I figure a back protector should be on my list of things to get, Im just new to the motorcycle game and a little unsure.

Make sure it will fit under your other gear, i.e jacket.

FYI Knox Aegis back protectors are reduced in price down to $295

Ok, so I'm not quite the dummy Mr Biggles is, but a vote for Knox here, using an Aegis 8R (I think) and the chest armour.

Had a lowside around 70kph, landing on my hip and chest, almost no marks or pains afterwards. Hip was a bit sensitive, but not much armour there.

A tumble after getting off the bike at 100kph, literally felt like a washing machine spin cycle. Zero marks/pain/etc and felt fine right afterwards.

I would always say you should be wearing back AND chest armour...
