So I have put my kids in snowpants with bibs the last few years..... when did you move away from snowpants with bibs?

I like knowing that they aren't getting snow down their pants or up their back - but will completely acknowledge how going potty stinks in these kind of snow pants.

When I try to think about being a kid - I think I wore bibbed snow pants well into childhood.....

I'm asking because I decided to go big/go home and buy a one kid road coat for each kid and get a pair of snow pants for free - I can't decide what size to order knowing I certainly won't use them this year....

(PS - our winter activities include sledding and playing in our yard - not skiing or anything intense...)
