A 2 L ambidextrous sling in 1680D CORDURA ballistic nylon with a detachable strap and rear grab handle.
Riders and travelers kept asking for two things: something sized between the Regular and the Max, and a sling that sits just as well on the other shoulder. The Pro delivers both.
The layout is fully mirrored, with double zippers on each side and a detachable strap, so it works on the left or the right. Mount the strap for a 90° sling carry on either side, or run it flat as a horizontal crossbody. A grab handle on the back lets you lift it like a small carry bag when you are not wearing it.
It holds 2 L and measures 22 x 18 x 5 cm (7.8 x 7.1 x 2.0 in), which places it between the 2.0 Regular and the Max. The shell is 1680D CORDURA ballistic nylon, one of the toughest bag fabrics around, and the zippers are water-resistant. Inside there is an upgraded RFID-blocking lining and a hidden RFID-blocking back pocket for cards. The steel anti-theft cable in the strap and the lockable zippers are carried over from the 2.0.
Quick to open, hard to tamper with and built to last, it is a sling for people who want more space without giving up security.
The two most common requests were a mid-size option between the Regular and the Max, and a sling that can be worn on either shoulder. The Pro is symmetrical by design: mirrored layout, double zippers and a detachable strap, worn angled like a sling or flat like a crossbody. It adds capacity and a tougher build, with 1680D CORDURA ballistic nylon, water-resistant zippers, upgraded RFID lining, a steel anti-theft cable and a rear grab handle.
One size fits all. The adjustable strap extends to a maximum of 51 in (130 cm) for any body type.
More room than the Travel Sling Bag 2.0 Regular. The Pro measures 22 x 18 x 5 cm (7.8 x 7.1 x 2.0 in) and holds 2 L.
Personal item friendly: at 22 x 18 x 5 cm it sits within the free under-seat limits of major airlines, including Ryanair (40 x 30 x 20 cm), easyJet (45 x 36 x 20 cm), United (43 x 25 x 22 cm / 17 x 10 x 9 in) and American Airlines (45 x 35 x 20 cm / 18 x 14 x 8 in).
RFID-blocking lining. The inside is lined with shielding fabric rated at a sheet resistance of 0.022–0.047 Ω and weighing 75 g/m². It blocks unauthorized scans while staying light, so credit cards, passports and IDs are protected from digital theft when you commute or travel.
A guided look at the symmetrical layout, the detachable strap and the compartments of the Pro.
Double zippers on a mirrored layout put your items within reach from either side.
A 1680D CORDURA ballistic nylon shell and water-resistant zippers stand up to daily wear.
A hidden pocket lined with RFID-blocking fabric keeps cards out of sight and shielded.
More space than the 2.0 Regular, at 22 x 18 x 5 cm (7.8 x 7.1 x 2.0 in).
The detachable strap can be fixed in different positions to suit how you want to carry it.
The mirrored design works equally well on the left or right shoulder.

I have one of the orginal sling bags, and while I still love it, I decided to try the Sling Bag Pro, and boy am I glad I did! The same great features of the orginal, (RFID lining, cable in the strap, zipper lock, etc) but with just a little more room. AND you can wear it however you want! switch shoulders, around your waist, whatever your mood is, this bag can make it happen! I would love to see it in other colors too!

Well made and so much more room than the regular size! This also seem like it will last a lot longer, too.
