## Description

Product Description We upgraded the original theft-resistant drawstring backpack to an even more secure sack. The Flak Sack II is the world's toughest theft-resistant drawstring backpack. It's made from our exclusive FLAKnit slash-proof fabric that achieves an A9 cut level, the highest there is! This lockable bag is like a portable safe for your valuables. 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. This bag doesn’t just carry your belongings, it protects them. Flak Sack II Our Story The story began in the Caribbean Sea with a vacation gone awry. Upon leaving his valuables on the beach unattended, Don Halpern became the latest unfortunate victim of daylight robbery. Having been stripped of nearly all his worldly possessions, Don began his search for a theft proof bag. After fruitlessly scouring the internet for a quality solution, Don happened upon a novel and innovative idea - a lockable backpack that would be both stylish and technically outstanding. LOCTOTE was born. Designed to protect, built to last Traveling to an unknown place, doing your daily commute, hanging by the beach or just find yourself in a busy place, the Flak Sack II is ready for the challenge. Our bags are designed to protect your belongings from theft and built to last a lifetime. This bag is the ultimate portable safe that allows you to live more & worry less. "As someone who travels a lot, this bag is a must have." - Kelli S. from Australia "It’s the brink’s armoured truck of backpacks" - Garry V. from California "My travel bag, work bag, and my portable safe, all in one." - Luca F. from Switzerland What makes our bags so special? Our Fabric Our exclusive FLAKnit slash-proof fabric achieves an A9 cut level, the highest there is! This soft, flexible yet almost indestructible textile takes anti-theft to a whole new, and almost ridiculous, level. Our slash-proof toughness comes from the superior cut protection of Honeywell's UHMWPE Spectra fibre, the same fibre used in police vests and military gear for bullet resistance. FLAKnit is what makes our bags the toughest in the world. There's nothing else like it on the market, not even close. Have peace of mind knowing your belongings are covered by this stuff.

Review: Not slash resistant - This bag is not what it claims, recommend people look up lock picking lawyer on youtube before purchase.

## Questions & Answers

**Q: Why is it so expensive?**
A: A lot of consumers are intimidated by the research they have to do to find the best product and will just buy something expensive assuming it must be good if it costs a lot of money.

Products like this exist for those people.

**Q: Lock Picking Lawyer just released a video where he easily cut through the bag in seconds, so how slash resistant can this bag actually be?**
A: I like his videos too.  You can easily stab/cut the bag like he demonstrated.  The bag is slash resistant in that you can’t just swing a blade and cut it, but that’s really the extent.

I have had my bag for a while now, and it’s pretty nice, holds up over time, and looks cool.  

I wouldn’t fill it with stuff and lock it to a random post though.  It’s more of an office security bag, not like six flags or something.

**Q: What makes this piece of trash theft resistant?**
A: Maybe the fact that nobody would want the piece of crap makes it theft resistant

**Q: Can it be cut easily with a pocket knife?**
A: This bag can easily be cut clean through with a cheap pocket knife.
