TSLA Kids Winter Snow Bibs - Waterproof Insulated Snowboard Overalls for Boys & Girls, Windproof Ripstop Ski Pants - Perfect for Snowboarding, Skiing & Outdoor Winter Activities

My 9yo just started skiing..Being it's his 1st year, I expected a lot of wrecks on the slope, and the 1st run down the hill, he fell ever 30 feet. Felt like it was going to take forever to get down the small hill...With the reinforced knee area and at the bottom of the legs, these held up great!He's only been out 4 times this year, but he's able to black diamond trails (proud I am). He's had his share of wrecks on them. And being these are steeper trails, the wrecks are a bit more harsh.. as in he might slide 30+ feet before stopping and there's not a sign of a tear or wear on these. Plus, he's said these were very warm.. He does wear long johns under them as his base layer. And to boot, I don't know what the ml waterproof rating might be, but there has been no water penetration.Bottom line.. Unless you're in the extremest of colds, I feel these will be perfectly find for kids to stay warm and dry.
