Steel reinforced locking strap

The secret is a patent-pending locking strap and heavy-duty solid brass lock that enable you to lock your bag shut, and to a fixed object. It's reinforced and grommeted with custom stainless steel components and 49 strands of stainless steel wire, making it nearly impossible to cut, break or tear without extreme force or heavy tools. The lock itself stores securely and out of the way behind the leather LOCTOTE logo patch.

SLASH RESISTANT ROPES

We created a rope unlike any other using a slash-resistant material (UHMWPE). Even though we hope no thief ever tries to cut this bag off your back, it's nice to know they won't be successful.

Solid brass lock

Lock machined from a single chunk of solid brass to ensure the security and durability of the lock. Easily set the lock to any combination you would like.

PREMIUM COMPONENTS & BUILD

Cheap hardware will ultimately fail. We use stainless steel and brass exclusively for it's strength, quality, and ability to keep looking good for years to come. Our bags are designed to protect and built to last.

WATER RESISTANT

Our bags are lined with a water resistant nylon lining and is equipped with a large (capable of holding an iPad) water-resistant interior pocket crafted with an Aquaguard zipper to keep your stuff as dry as possible.

RFID blocking interior pocket

Protect against RFID electronic pick-pocketing. Our bags include a large internal pocket lined with a certified RFID blocking material to shield credit cards & passports from unauthorized scanning.

STERNUM STRAP

Gives you that extra security and comfort. By keeping the ropes centered across your chest, the bags stay secure with its weight comfortably distributed across your shoulders.

Simply amazing.

I recently upgraded from the Flack Sack I to the Flack Sack II (Coalition) and couldn't be happier. I had been traveling with the original flack sack for months and wouldn't go without it anymore - especially on over night bus trips, while working out at the park, dancing at the club or just using crowded public transport - it has always kept my belongings safe and me worry-free. The coalition seems sturdier than the original one, I love that it is vegan and also its overall appearance is simply much cooler. Plus you get more pockets on the inside for organization. 100% recommended.

Just what I needed

It is a little stiff and difficult to get the grommets close enough to lock in the beginning, but with just a few days of working with it, it has softened up a lot. I love knowing no one is rummaging through my stuff.
