I ride with this Leatt Back and chest protector - I never notice its on when riding, and its a serious bit of kit in terms of protection offered. The do a should version, and full upper body version too, but I find them a bit more restrictive. They integrate with the Leatt neck braces tooKnee pads and spinal protection reduces the risk of a ride stopping injury - the sort of event that involves an uncomfortable carry me out of here experience. Non negotiable protection imho.
Elbow pads are barely noticed whilst riding yet reduce the risk of an annoying injury - peeled back forearms rake weeks to heal. They also encourage tuck and roll fall techniques which seems to reduce wrist injuries .Plus they're sun protection. Most of the time gear for me.
Protecting ribs , wrists , and shoulders is more challenging - you have to weigh the reduced agility / increased risk of having a crash vs the potential benefit from the armour. I'd love to hear a convincing argument, but I can't get enthusiastic about any of the sauna suits out there. Zimm - you mention a right of way tree negotiation - I guess I'd be concerned about the sweat suit spreading the load and fracturing multiple ribs rather than just a couple? A brocken rib is inconvenient, but a flail chest with punctured lung gets a chopper flight . Perhaps it's more about selecting WHERE the ribs break? The further forward the better - less numb chest wall from intercostal nerve damage? I really miss a good back scratch....
I'd love a decent, well ventilated chest, spine and shoulder defence suit - especially if it integrated neck protection. But it might be easier to squeeze myself into a hot cupboard and watch youtube videos whilst the kids throw things at me?
