LOCTOTE™ bags are crafted from the Most Advanced Slash Resistant Fabric available. The Flak Sack is made from a double layer (twice the protection). Woven from a proprietary blend of ultra high molecular weight polyethylene (UHMWPE) 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 — yes, even more slash resistant than Kevlar®. 

Simply put, no fabric available today is absolutely 100% cut-proof. That said, our bags are the most slash resistant you will find in the market. So how resistant is it? We acquired a shirt made from the same fabric, and then shot a video to demonstrate that we don’t just say that we stand behind our claims, we literally stand behind them.

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.


As RFID radio transmission technology is becoming increasingly widespread in passports, credit cards, debit cards, identity cards, key cards, and access control cards, the risks of “electronic pick-pocketing” (identity and personal data theft,  payment fraud, and unintentional contactless payment) are on the rise. Without shielding, unauthorized parties can read the data stored on these items with the aid of an RFID reader, from a distance without any direct physical contact. Each LOCTOTE™ bag comes with a large water resistant internal pocket lined with a certified RFID blocking material which effectively shields all contactless credit cards, passports, drivers licenses, and bank cards that operate at 13.56 Mhz and above (13.56 Mhz interface is the one that typically contains personal data).


Stuff happens! Rain, spills, splashes, puddles, high-tide, and general carelessness are the enemy of your small electronic devices and leather goods. Each LOCTOTE™ bag is treated with an industrial water repellant coating, and comes equipped with a large (capable of holding an iPad Mini) water-resistant interior pocket crafted from urethane coated 200-denier nylon, heavy-duty coated-polyester thread, and a color-matched water-resistant zipper to keep your stuff safe & dry from the perils of an active lifestyle.


You won’t believe it until you feel it… LOCTOTE™ bags are brutally durable yet suprisingly soft and supple. It’s no surprise, when you consider that they are constructed of a fabric originally developed to be worn against the skin. They are so soft that you can actually use them as a pillow, and to prove it, I stuffed one of our bags and had my daughter sleep with it as her pillow every night for a week. She found our latex-free fabric to be soft, comfortable, non-abrasive, and non-irritating. Unfortunately, my wife cannot say the same thing about my approach for testing softness…

This is the bag you’ll want to take with you everywhere like a trusted friend. They are comfortable to carry, foldable, packable, crushable, wrinkle-resistant, hand-washable, UV resistant, latex and gluten free. Whether you’re dressed for the office, the gym, the beach, or a night out — LOCTOTE™ bags are a soft reliable friend that will protect your stuff from thieves, and you from bland accessories.


When you start with a blank sheet of paper you get to re-think everything. That’s what we did with this bag. We considered the best way and the best materials each step along the way. We purposefully over-engineered, over-designed, and over-built. Nothing was left to chance, and in the end we created a product that is functional, packed with features and built to last.

  • Oversized swivel snap key clip keeps your keys secure and handy
  • LOCTOTE™ badge doubles as a pocket to conveniently store your lock or ID
  • Heavy-duty UV resistant bonded polyester thread used throughout the bag ensures strength even after repeated use and prolonged exposure to the sun
  • Custom-made double-braided nylon yacht rope is flexible, strong, and pleasant to the touch
  • Multi-loop allows you to hang the bag on a hook, or secure the top opening extra tight
  • Micro-fleece lined interior pocket
  • Customizable 3-digit lock combination
  • Matching sternum strap

The grey undershirt is made out of the same fabric as our bags.

Please do not try this. Just because we do a lot of dumb things, doesn’t mean that you should too.
