I'm sick of paying hundreds of dollars for winter outer wear only to realize that "waterproof" isn't waterproof, and once something is waterlogged it's certainly not keeping the "good to -XX degrees" claims either.

What brands/products have you used for your kids that actually live up to their claims? girl winter coats

Preferably that holds up to daily wear in -30C temperatures/deep snow. Maybe it's a pipe dream but I'm hoping some of you have products you swear by!
