Hey,
I have some scab knee pads that i am not using anymore (im size 18 and find they fit fine)
- but-
im not using them because the padding has compacted (this happens over time) i would suggest that it maybe worth spending the money on new knee pads - as this is what you fall on the most and maybe getting second hand elbow pads and helmet?
your welcome to try my knee pads if youd like though
