After the third crash in a year in which he's damaged his back (not seriously, just stiff for a couple of weeks), a friend of mine is seriously considering buying some kind of spine protection. His riding style is more towards the aggressive side of XC but not really all that crazy.
I think it might be overkill personally and suggested that, at the most, he should look at a hydration pack with built in spine guard. I have no idea if these are any good though.
So… does anyone have any experience of hydration packs with spine guards (specifically thinking of the EVOC ones), or do regular, 'ordinary' riding with back protection?
And before anyone says, I've suggested he might need a skills course (or at least to learn when pre-jumping is the better option) 🙂
