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.

I LOVE IT!

This bag has overall been everything I expected it to be. It is a very nice and well crafted item that is exactly what it says it is and is what you expect. Not only was it easy to change the combination lock, but has been useful for when I just need to leave it somewhere and not worry. It is very knife resistant like it claims to be, I tested it myself when I received it because this was one thing I was nervous about when I purchased it. However, it has proven to be the handy bag I have always wanted and needed as a person who travels with a bag everywhere. I highly recommend this bag to anyone who travels and worries. It is well worth the money I spent and I'm sure it will last a very long time given what it is made of. Thank you Loctote for this FANTASTIC product.
