its down to personal preference to be fair.
I have noticed a few players down my way have bounce vests and they say it helps not only reduce pain but also increases the chance of balls bouncing (of the times I've played along side them, I have yet to see it happen
) Then again, I'm sure quite a lot of players use em hah so they must work to some degree.
as for chest protectors, I rarely see anyone use em (punter or player).
now just out of curiosity, do your friends play a lot and with their own gear?
If so, they may be referring to a bounce vest in which case, up to you.
if not, could be they don't like being hit and trying to warm you of it. (doesn't hurt that much
)
i don't know, just taking a guess
hope this helps
