HOW IT WORKS

TECHNOLOGY & FEATURES

slash-proof (a9 cut level)

FLAKNIT FABRIC

STEEL REINFORCED LOCKING STRAP

The steel reinforced locking strap and heavy-duty solid brass lock enable you to lock your sack shut, and to a fixed object. It's nearly impossible to cut, break or tear without extreme force or heavy tools.

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.

SLASH RESISTANT ROPES

Made with a cut resistant core interwoven with a highly-reflective material for night visibility. 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.

RFID BLOCKING TECHNOLOGY

Protect against RFID electronic pick-pocketing. This sack has an internal pocket lined with a certified RFID blocking material to shield credit cards & passports from unauthorized scanning.

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.

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.

DESIGNED TO PROTECT, BUILT TO LAST

Traveling to an unknown place, doing your daily commute, hanging by the beach or just find yourself in a busy place, the Flak Sack II is ready for the challenge. This bag is the ultimate portable safe that allows you to live more & worry less.

Substantial bag!

This is a substantial bag that is extremely well made. It is a bit heavy, which I knew before ordering. I hesitated a lot between the lighter weight Sports Sack and this one, and decided on the Flak Sack 2 because it is a little bigger. The safety level of the Sport one is probably sufficient, but the Flak is already not that big, so I am glad I took bigger one. I was able to just fit a 17" laptop + file folders + book. At first it was difficult cinch and the eyelets out to lock it, and after using it a couple times it is getting easier I love the simplicity of the design the attention to every detail and extreme quality.

Flak Sack II

Thank you. This bag is exactly what I wanted. I use it to lock my belongings to my motorcycle while I’m away from it. The only thing I would change is the eyelets that you put the padlock through, if there was another couple placed in the strap I could stuff my motorcycle jacket in there too. I love it and I really think you have a great product. Thanks for everything, from the ease of ordering the product to the the surprisingly quick delivery. Thanks again, Tracey.
