VB - I've used bamboo in t-shirts & knits & it is very good - very soft!. Make sure the wearer trials do a good few wash tests though - the stability can be less good than cotton. Can you do them for the same price? That's good (if yes!)
It might be a few £$€ more for the bamboo, but it sounds like the benefits are worth it. Trialling them is the only way to be sure.
