These are definitely the best waterproof overtrousers for £40 that we tested. In particular they get a long leg zip, making them very easy to fit over boots. That zip also has a double stormflap with press studs, so it will keep out far more water than an exposed water-resistant zip for example. An even nicer addition is the ability to vent the side zip from the top, for when you overheat but don’t want to remove your overtrousers. For extra comfort there is a lining too, while the elasticated waist and drawcord are standard for this price, and effective. A superb price for what you are getting. But you do not get a stuffsack or pockets. Perhaps more importantly you cannot adjust the ankle cuff to prevent it from flapping about. Some are lighter too, of course, while others have additional features, such as articulated knees. But for the price these drawbacks are acceptable.
