The black Action X40 V2 Backpack from Shimoda Designs has a 40L capacity and offers photographers a compact, durable carry solution that allows fast access to gear. Two padded sleeves hold and protect laptops or tablets up to 16". The roll top access allows you to expand or compress the volume depending on your needs. There are multiple attachment straps including TPU compression straps for increased durability when attaching bulky items such as skis. The removable helmet holder secures a bike or ski helmet to the exterior of your pack.
The pack's interchangeable and adjustable shoulder straps feature two zippered pockets to carry the latest pro-sized smartphone, a water bottle, or personal accessories. The removable waist belt offers stability and weight distribution when carrying heavy loads and the trolley sleeve attaches to your rolling luggage handle for seamless travel. Two removable pouches hold a tripod or water bottle and can be moved to the waist belt for instant access or removed completely. A hidden sleeve is designed to hold an AirTag so you can locate your pack if it gets lost or stolen.
