This new Apidura Backcountry Hip Pack is a great way to expand your carrying capacity without loading up your back. It's super well-designed and fully waterproof. We've been running them as camera bags for easy access snapping en route add-on or as a stand-alone pack for when you're out for the day and want to keep things minimal, but with enough room for the essentials if the weather changes.
It is made from an intelligent mix of materials in all the right places: breathable mesh and durable, waterproof nylon ripstop. It has a main compartment with internal pockets and two easy-to-get-at external pockets for snacks and tools. The waist strap has a fast close elasticated velcro tab, with a secondary secure buckle to dial in the fit—a bit of hi-viz detailing seals the deal.
