This padded nylon shoulder strap is strong, adjustable and easily removable. It fastens quickly with carabiners for an easy but reliable connection. Originally designed for our EXFIL-80 bag, but let's be honest... it turned into a hugely popular luggage accessory for all other compatible EXFIL® bags in our lineup. many other non-Biltwell luggage bags or anything else you can think of. A great all purpose shoulder strap for sure.
