Put your gloves on before you put on your jacket
I don't have a problem at all with my jacket; short gloves pretty much all year round making use of heated grips and muffs if the weather dictates. Alpine SMX Air's are my fave as they double up as a good off road glove.

On the odd occasion that I wear heavy, cuffed gloves, I just tuck the jacket into them and can honestly say that I have never had water run into the gloves.
I genuinely don't see what the problem is
