Got these for my 7-year-old. I deliberately bought a size up because I'm hoping they'll last through next year. I adjusted the straps to their tightest, and now the pants fit great! My boy was able to spend 4 hours out in the freezing cold, thigh-deep in snow, and came back in bone dry and even sweating!

Plus, if you've looked at prices for decent snow pants, these are quite a deal. Highly recommended.
