The black Slingshot SL 250 AW III from Lowepro is a versatile sling bag that features two main compartments, including a camera compartment along the base of the bag that can be used to hold a small DSLR or mirrorless camera body with three or four lenses, including an attached 24-70mm f/2.8 lens. Positioned so that it can be reached when the bag is rotated from one's back to front with its left side facing upward, the camera compartment's zippered, peel-away opening includes an internal clip system that allows the wearer to ensure that the zippered opening provides side access only. Alternatively, the clip system can be released so that the peel-away opening can be fully unzipped and retracted, enabling complete access to the camera compartment such as when the bag is placed on a flat surface with its shoulder strap facing downward. Above the camera compartment, a top-facing zippered storage compartment can accommodate packable clothing and features organizer pockets which can be used to store travel documents, camera batteries, memory cards, or small electronics.

When the Slingshot SL 250 AW III is in use, the two main compartments rest behind the shoulders. Accessible through the top-facing storage compartment and towards the side of the sling bag that rests against the wearer is a slip pocket with room for a 13" laptop computer. For items that need to be reached quickly and conveniently, the front panel includes a top-facing zippered pocket as well as a front-facing zippered pocket. These pockets can be used as spaces for a notepad, maps, or snacks; and their zippers, like the zippers for the bottom camera compartment and the top storage compartment, each include a large pull that can be easily gripped. While a stretchable side pocket on the wearer's right side can hold a water bottle; a small tripod or monopod can instead be stored within the side pocket.

For an enhanced fit, a removable under-arm strap is included. When used with the shoulder strap, the under-arm strap helps to prevent the sling bag from unintentionally shifting around the wearer such as when travelling over rough or uneven terrain. Constructed for durability while remaining lightweight, the Slingshot SL 250 AW III is built to be weather resistant and includes a seam-sealed cover for use under heavy rain.
