In Germany you can still buy 40 kg sacks (but 25 kg seems the default?) but it always seemed very stupid to me. Rather move something half the weight twice than twice the weight once.
However if you are doing it professionally, why not have your underlings move twice the weight? Time is money and all that, besides, if you don’t do it, your competitors probably are so if you don’t want to go under, you’re going to have to do the same thing.
