After having my stuff stolen from the beach, I set out to purchase a bag I could lock shut and lock to something that would keep my stuff safe. When I realized that all the existing locking bags could be easily cut open, I invented the Flak Sack in 2016. The Flak Sack was the first locking drawstring bag ever to be constructed completely from advanced cut resistant textiles. Before that, theft resistant bags locked to a stationary object still left their contents highly vulnerable to thieves.

We get lots of questions daily about our bags with regards to their benefits and limitations. Many of the questions focus on whether these bags are bulletproof and cut proof. We didn’t create a miracle, just a really tough practical bag using the latest technology advancements. Today, I’m going to set the record straight on these attributes.

No textile is “bulletproof”. Don’t believe any silly videos or photos that imply otherwise. Certain textile materials such as aramids (Kevlar) and ultra high molecular weight polyethylene (Spectra, Dyneema) can be woven, stacked, and assembled ¼” thick or more to provide a bulletproof trauma plate, but this configuration is way too heavy and stiff for a bag. Even if a thin material could actually stop a bullet (which it can’t), the back deformation and lack of energy dissipation would still cause severe trauma. No drawstring bag on the market today is bulletproof.

Nothing is cut proof. However, with the invention of technologically advanced super fibers, and super textiles (e.g. FLAKnit), we are able to produce highly cut resistant fabrics. Highly cut resistant means that a thief with a knife or a pair of scissors will have a really tough time getting in to it. How tough? Well it depends on the cut level. For example, our Flak Sack COALITION is an ANSI 105 cut level A9. There is none higher. We’ve bent and broken knife blades on it.

When we talk about our products we frequently talk about cut resistance levels. Some of you may be wondering what this actually means, so without going into too much detail, I will explain it. Cut resistance is the ability of a textile to resist cutting by a rotating blade being pressed against it, or a non-rotating blade being moved back and forth against while force is being applied. There are two major global standards used to evaluate the protection levels of cut resistant textiles: ANSI/ISEA 105 (U.S. Standard) and EN 388 (EU Standard). ANSI/ISEA 105 now uses a 9-level score (A1-A9) and EN 388 is moving to a 6-level score (A-F). The higher the score, the more cut resistant it is. The very top EN388 level (soon to be renamed level F) is only equivalent to an ANSI 105 level A6.

At LOCTOTE, we independently test our fabrics and our finished products. Nobody to date has managed to create a more cut resistant bag than us. Our new proprietary textile FLAKnit achieves an ANSI cut level A9. The next closest bag to that in the marketplace achieves an ANSI cut level A5. We pride ourselves on innovation, honesty, and transparency. Creating new high-performance products is our passion, and we will continue to push the limits on bringing them to our customers. Rest assured that when you purchase a LOCTOTE, you are purchasing the very best products available.
