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

Does what it says!

Our belongings were secure in the Middle East in public places and on our backs. It’s a bit of a hassle to open and close, though. Especially at first when it’s still stiff. My only recommendation would be to add a small outside pocket. Maybe on the side that would be against my back. It would be nice to have faster access to important but easily replaced items such as lip balm or sunscreen.

Safety First

Traveled to Estonia and Latvia recently and wasn’t concerned about my personal stuff being stolen from my Flak Sack II. In crowded areas felt that the security of the locked bag a great hindrance to the thieves.

Awesome Bag...peace of mind

I am so glad I ordered this bag...I've always been wanting a bag that I can secure while I quickly step.out to do something like use the restroom or when I go to the park or beach, to secure my belongings somewhere. It definitely gives me more peace of mind. I've already got asked where I got it while out and about. . Great customer service too.

Excellent Prodcut

I absolutely love this product. I bought three Flack Sack II (one for myself, one for my cousin who is a freshman in college and one for my cousin who is in high school.) I use this bag for my work travels and it fits my Lenovo Yoga 920 with no problem and I love the peace of mind I get from this bag when traveling. I recently purchased the Antitheft Sack 3L for those days when I'm at a beach or hotel pool, etc. and only need to carry my phone, wallet and car keys. I'm very impressed with the quality and enjoy these bags!

Nice bag overall

The bag looks durable and visually appealing. I have 2 issues with the bag. For me, it was very hard to cinch the bag closed to get the eyelets exposed to look it and it is heavier than I expected. Overall, I would recommend it.
