How it works

Technology & FEATURES

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 fiber, the same fiber used in police vests and military gear for bullet resistance. FLAKnit is what makes our bags the toughest in the world. Have peace of mind knowing your belongings are covered by this stuff. Don't believe us? Test it yourself with a FREE fabric square.

Better than I expected

When I was interested in the bag I had no idea how high of a quality the bag would not only feel, but perform. It’s my go to daily carry, and had space perfect to carry what I’ll need while still looking great. If you’re thinking about getting this bag, get it. It was well worth it.

Time Will Tell

i've Been using my Flack sack ll for about 2 weeks now and i use with the confidence that it will do all that it says it can....with that being said i do use it with pride. The lock that comes with it leaves much to be wanted as i was locking up my bag had the combo changed on me and spent the next 2 hours running through 000-999..imagine if i had the bag lock to a fence!!

Love it!

I purchased this bag for an upcoming trip to Europe, but in the meantime have been using it while walking and biking around the city. It really holds a lot - gym shoes, 2 water bottles, wallet, with room to spare. It is comfortable to wear and I'm excited to use it on my trip - and confident that it will protect my belongings securely and stylishly. Additionally, I had a fantastic experience communicating with customer service ... thank you!

We created a rope unlike any other using slash-resistant material - Ultra High Molecular Weight Polyethylene (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.
