Product Description

The Flak Sack by the Loctote Industrial Bag co. Is the toughest drawstring backpack ever. This slash-resistant bag is like a portable safe for your valuables. It was designed to accommodate the lifestyles of people on the go who need their essentials with them, but are not able to be constantly looking after them. Simply lock the bag closed or to any secure object – and leave it without worrying about it being tampered with or stolen. This bag doesn’t just carry your valuables, it protects them.

From the Manufacturer


LOCTOTE bags are crafted from a double-layer of the Most Advanced Slash Resistant Fabric available. Woven from a proprietary blend of high molecular weight polyethylene (HMWPE) and other state-of-the-art fibers, the fabric was originally developed for use in high performance body armor and personal protection under-garments for law enforcement, corrections, and security workers. Our bags have the highest possible Blade Cut Resistance ratings (Level 5) based on international (ISO) and European (EN) standards.


Pull it, lock it and leave it. It’s that simple. The patent-pending locking strap and heavy-duty solid brass and steel lock enable you to lock your bag shut, and to a fixed object, enabling you to go about your business without worry. Tested to over 1,000 lbs, the cut and break resistant nylon lock strap is reinforced 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.


Large RFID-blocking interior pocket protects your credit / debit / ATM cards & passport from unauthorized scanning.


Water resistant coating and large water-resistant interior pocket keep your stuff dry from spills, splashes & rain.


Lightweight, comfortable to carry, foldable, packable, & UV resistant. LOCTOTE bags are a soft reliable friend that will protect your stuff from thieves, and you from bland accessories.

Your bag shouldn't just carry your stuff, it should protect it.

About the Startup

Innovative, Secure, Authentic

How did you come up with the idea for this product?

The idea behind LOCTOTE came as a result of a family vacation in St. Croix. My wife and kids had all gone back to the room for the day, and I decided to stay out on the beach and do some snorkeling. Before heading out into the water, I put my phone, earbuds, and cash in my shoe, which I covered with a towel and left on a beach chair. I swam out about 100 yards, and when I looked back to shore, I saw an individual shuffling through my stuff on the beach, and then walk away with something in his hand. I yelled to him, and swam back to shore as fast as I could, but by the time I got there, both he and my stuff were gone. This was a real downer for the vacation, and I decided that I needed a solution to prevent something like this from ever happening again. - Don Halpern

What makes your product special?

We invented it. We continue to improve it, and we’re a real company that won’t ignore you after the sale. Beware of knock-offs. Only the Flak Sack has these features.. • Made from a double (not single) layer of perpendicularly-aligned advanced cut-resistant fabric – more than twice the strength and cut resistance • Locking strap made with with military-grade brass grommets physically integrated into a patent pending custom machined stainless steel and aircraft cable internal mechanism – will not tear out. • Custom-made solid brass lock (3x the weight of a competitors flimsy lock) for superior strength• 20% larger • Internal pocket lined with micro-fleece and shielded with a certified RFID-blocking material • Entire bag treated for water and stain repellency (not just a small internal flap pocket) • Super-soft and flexible heavy-duty 8mm nylon-core cut-resistant ropes • Special military-grade #4 brass grommets set using a patent pending method will not pull out like other bags can (can withstand over 10x the force of other bags) • Separate rope and lock strap channels prevent tangling • Precision design and tight manufacturing tolerances means the bag closes tighter (4x smaller at the opening) than competitors • Heavy-duty 5mm stainless “O” ring cannot be snipped with simple hand tools and has over 2,000 lbs breaking strength. • Patent pending multi-loop makes it convenient to hang or attach the bag to other items, and can be used to provide an extra level of security. • Exterior pocket (leather) provides a place to store the lock, and prevents it from banging or damaging surrounding things •Matching (leather) removable sternum clip
