For when you can’t work out if you want shorts or trousers… here’s the Convertible Cargo Pants. At first glance they’re a pair of hard-wearing military inspired outdoor pants made from lightweight nylon with pockets and an in-built belt and all that other important stuff, but look close and you’ll see they’ve actually got some handy zips just below the knee allowing them to transform majestically into shorts. If you’re only taking one pair of trousers on that hiking trip, then these might be the ones.
