Cheapest waterproof overtrousers I could find, but still seemed good quality. Will find out when they are taken on Swedish wilderness canoe trip!
Drawbacks: these trousers do not have pockets, only come in one colour (black), and only come in two lengths – 30" or 32". I ordered the longer length but ideally would have liked a 34" option (I'm 6' 4") and your pickers need to be more careful – I was sent the 30" trousers and had to take them instore to exchange for the 32". However, service in the store (Putney) was excellent.
