The thing about waterproof trousers is that you only want them when it's wet, but when it's wet, you don't want them to be a faff to put on: that's why The North Face made the Venture Half Zip Pants.
When the weather's being friendly, the Ventures stuff easily away into one of their hand pockets and stow in your bag, weighing in at just 220 grams so you can just forget they're there. When you have to get them on to avoid a soaking though, the half-length side zips allow your booted feet to sail straight through, for instant waterproof protection.
