I've still not found knee and shin protection I like. None of it is comfortable. Maybe that Bohn gear would be alright but look pretty dorky i think.
But the six six one chest protector is great for everything up top.
I've not been wearing any extra protection except minimal gear though, too darn hot for anything else. I tried to quit crashing so much, sometimes that works - sometimes not.
I did just install a MT75 wheelset though but haven't rode it yet other than around the house, need to get some sealant and go tubeless. Rains have washed out a lot of our trails nearby, have to drive 90 miles to get to good trails.
