While traveling, I needed to find a way to tether my bags together, so I wasn't having to monkey with a backpack and sling bag. Then realized that I was wearing my paracord bracelet. Using my bracelet, I looped it through my handles on both bags, and tethered them together making a run from airport terminal to terminal much more manageable. With that in mind, I saw people with same issues.
Designed a heavy duty strap with HK hook and D-Ring loop on the opposite end, can easily wrap this between your backpack handle and roller bag to easily run through the airport, saving your back and easing a bit of stress.
Made from Type III 550 paracord, with 7-inner strands and Made in the USA, this strap is made with 20ft of cord, and woven by staff in the USA too.
