Waterproof trousers appear strong and well made. Sizing seems accurate, I bought 2 pairs for my sons, 7-8 years and 9-10 year. Both fit great. Fit comfortably over normal trousers. Kids love them, no more wet jeans. Service from supplier very good, they actually dispatched the wrong size but were very very helpful when I phoned them. Sent the correct size out the same day, I received them the following. Very happy customer!
