The Action X40 is designed for aggressive photographers with serious gear needs. It's an efficient and fast-access backcountry camera bag, built for action in foul weather, ever-changing environments, and challenging terrain. The X40 is designed to carry gripped bodies and will comfortably fit most mirrorless and DSLR cameras (up to 6.7 in or 17cm tall) via our DSLR Core Unit series. Its roll-top access allows users to expand or compress the volume to the demands of the day. It features multiple attachment straps, including TPU compression straps for greater durability when attaching skis, and its removable helmet holder lets users secure mountaineering, ski, or bike helmets to the outside of their pack. Action X's interchangeable and adjustable shoulder straps feature two zippered pockets to carry the latest iPhone Pro Max phones, a water bottle, or personal accessories. The Action X25, X30, X40, and X50 feature side camera access and two removable tripod or water bottle pouches that can be moved to the belt location for instant access to key accessories like snacks and lenses, or removed completely to save weight. Two padded sleeves protect laptops and tablets up to 16 inches. Finally, the removable belt, luggage-handle pass-through, and hidden AirTag sleeve make the Action X40 a stealthy and stylish partner in urban and travel environments. If you need to carry a gripped camera body and still want a relatively small pack, this is the one for you. *This Starter Kit includes an Action X40 Backpack, Medium DSLR Core Unit v2, Helmet Holder, and Rain Cover.
