The Berghaus Mule 40+20 Expandable Kit Bag is the least technical-looking of the bags on test, yet it is able to expand in capacity by 20 litres, making it a particularly versatile choice. It could comfortably function as a hillwalking tool or as a general-purpose bag for travel, gym clothes or work use.
The Ardura fabric construction is more supple than most on test, but should provide a decent level of durability, while the number of straps on offer is comprehensive. The two opposing top-mounted handles are particularly soft and comfortable to hold, while the larger mid-mounted straps (which could be used as shoulder straps, though they aren’t designed for it) come with a clasp. There is also a detachable, centrally positioned strap that attaches via a pair of sprung clips. The underside of the main flap comes with a large zippable netted pouch, while a zip-up pouch on the outside provides extra storage space.
The main selling point of the bag comes courtesy of two subtle 10 litre zip-up extensions, which – when undone – allow either end of the main body to expand considerably. The extra space bulks up the standard 40 litres to a more sizeable 60 litres, while transforming a general multi-purpose duffel into a more versatile expedition bag.
Coming with lockable zips, Berghaus Mule 40+20 Expandable Kit Bag is the most flexible of the duffels on test, and it can span a number of uses easily and effectively.
Material Ardura 1000 D
