I wore 661 Evos for a long time after I broke my hip- not just to protect the injury but also because the entire leg was just generally easier to upset, and even reducing everyday brusing in a fall was still really worthwhile.
The big thing i found was that half the shorts I tried just didn’t really cover the right parts at all- you got massive thigh protectors which realyl aren’t that useful, and not enough around the bony protrusions. So that’d be my only really useful advice, fit is realyl important.
POC’s ones would have been great for me except for the stupid wee chamois.
