We have no issue with how the hardware functions they’re just really big and bulky. We’re also happy to see Duraflex hardware for the two large buckles on the strap and the adjustment slide on one end. Aer Tech Sling 3 | You won’t have an issue using these big Duraflex buckles to undo the strap. The top pocket zipper lacks those features yet locks down into place so it’s not jangling around as you walk. There’s also a cylindrical piece of plastic at the end to provide a better grip and make it easier to spot the black zippers against the black bag. The main compartment YKK zippers have metal pulls with cords woven through to make them easier to grab. There’s a carry handle at the top that’s small enough to hang on a hook yet comfortable enough to carry like a briefcase if you want to take off the strap, which you very well may want to do-more on that in the Fit Notes. Aer Tech Sling 3 | The padded handle is comfortable to use for carrying the bag. There’s no big logo or letters splashed across the front to let everyone know whose bag you’re carrying the sling’s aesthetics speak for themselves. Aer puts its branding on one Hypalon tab on the bottom right side with its name printed in small white letters. It’s not super shiny, and we like that you can blend easier into the crowd of commuters. It’s solidly built, with 1680D CORDURA® ballistic nylon around most of the bag’s exterior and an 840D nylon face coated for weather resistance.

However, this isn’t a fanny pack from the last century style of sling it’s a laptop bag with one strap. It’s nice to have options, especially if you don’t like to rock a backpack, but is this a sling you want to swing crossbody for your next trip? Let’s find out. We’ve got a Tech Pack 3, a Day Pack 3, a Tech Brief, a Cable Kit 3, and, wait for it, a Tech Sling 3.

Aer Tech Sling 3 | You can carry your tech crossbody with this sling. If you’re designing a Tech Collection, you probably would focus on things like a tech pouch and a laptop bag, right? Well, you would be right! Aer’s done that with an updated line of bags that they’ve translated from the Work Collection into the Tech Collection and then some.
