Loctote Flak Sack II Anti Theft Backpack Review – $129.00

It all started last week. My wife and daughter were at the community pool, it was a blistering 90 plus outside and the place was packed. We grabbed a patch of grass by the fences, about 30 feet from the water. We had brought our phones and wallets with us and obviously couldn’t take them in the water, so we took turns swimming with our daughter. It was ridiculous. It was after that ordeal that I started looking for a secure option to store our personal belongings when out and about. That’s how I found out about the Loctote Flak Sack II Anti Theft Backpack.


The Flak Sack is built like a traditional drawstring pack with some very interesting features. The fabric is made from Loctote’s proprietary Flaknit, a highly slash and abrasion resistant material. Loctote states this bag scored an impressive A9 cut level. I believe this is an actual ANSI based guideline, so this rates up there for safety equipment used in industrial applications where contact with dangerously sharp materials is performed frequently. The drawstrings are also made of slash resistant textiles. The bag has a large open compartment with a smaller RFID blocking fleece lined interior. We also see a steel reinforced locking strap to keep prying hands out.

The bag weighs about 2lbs empty (including lock) and measures in at 18”x14”


The Flak Sack II functions much like your standard drawstring bag. The material is a little rigid and less pliable than nylon, which is kind of expected given the security features. The main compartment makes stowing gear pretty easy, but this bag will fill up quick, and you can’t stuff it to the brim. I found out the hard way because you can’t cinch it completely shut and get the lock on if it’s packed. So definitely try to keep the bag about 75% loaded at most. 

The drawstrings are also slash resistant. I think it would have been great if they had steel cable running through them to add even more reinforcement. There’s video of guys making multiple attempts at slashing them though with little success though, but you’d have to be at it awhile and cause a scene to get this bag open. The locking function is pretty easy once you see it done on video. Once secured the bag is cinched so tight you can’t even get a finger inside the bag.

The major selling point for me is the ability to lock it to stationary objects like posts or fences. I wish I had this bag in college. You could leave your expensive electronics locked to your bedpost! The RFID blocking feature is a nice bonus, although I pity whomever wasted their time trying to get into my laughable finances in the first place.


Drawstring bags aren’t typically great looking, usually towing the line between teenager at soccer practice and gym bro man bag. However Loctote did a nice job “adulting” it up a bit. The material is inherently thicker, so the bag has a more quality look and feel to it. The leather accents really do a great job at adding a subtle flair to the bag. It comes in a few other colorways like heather and digital camo if you want something a little more conspicuous. 


I want to point out that no anti theft device is fail proof. However, Loctote’s Flak Sack II definitely adds peace of mind when storing your goods. The fact that the Flak Knit material is so resistant to cuts and punctures just adds to the “It” factor. I like the fact that I’m wearing a bag that could quite literally double as a shield against edged weapons. I wish it was a little bigger and cost a little less, but that’s the price of innovation. All in all, it’s definitely worth a look if you travel with a lot of expensive goodies and find yourself away from your pack at times.

Triple Aught Design Fast Pack Litespeed Backpack Review – $255

I’ve been somewhat of a backpack (that’s a bookbag for you east coasters) connoisseur ever since I got my first leather bottom Jansport in the 5th grade. Ever since I’ve been experimenting with carry options. I had a bag for travel, school, work, etc. Having so many bags laying around was starting to become ridiculous however.  It was there that I started searching for the one bag to rule them all and in the darkness bind the- excuse me, what I meant to say was that I wanted a bag that could adapt and meet the needs of nearly any activity I could throw at it. In that search I discovered the FAST Pack Litespeed by Triple Aught Design.

An almost unparalleled amount of detail is poured into this bag. The price tag seems justifiable when you realize it’s not only made in the US, but it probably took someone quite a while to build it.

The Fast Pack features several advanced textiles in its construction. The exterior shell is made from 1000 Denier Invista Cordura Fabric. In case you’re wondering, Denier refers to the fiber thickness of individual threads. Typically the higher the number, the more durable the fabric. For reference, most Jansport packs are 600D. This pack also sports YKK zippers with paracord pulls and pretty much all the plastic buckles are ITW GhillieTEX.

Padding in the shoulder straps and back are sourced from Evazote Closed Cell Cross-Linked Ethylene Copolymer Foam. I fell asleep during rocket scientist class but a bit of research reveals this product has many uses in products over a vast area from gym mats to industrial gaskets. If this stuff performs in a Mack truck then surely your tender shoulders will be in good hands.

The back padding utilizes DRI-LEX Aerospacer Moisture Management Mesh. This mesh is often used in shoes and is noted for its moisture redistribution system. Essentially soaking up the sweat off your back and transporting it elsewhere.

Hypalon is  Synthetic Rubber is used in specially reinforced areas. This is another high tech material with great resistance to chemicals, temperature extremes and UV light. If you’ve ever found yourself in a life raft, chances are it was made of Hypalon.


The TAD Fast Pack Litespeed is designed to be a light, relatively compact bag for minimal carry…with the modular potential to do so much more. One could write a lengthy tome on the functionality of this bag. Out of the box it has a large main compartment with a clamshell design that opens up to two mesh zippered pockets. The outside has a small zippered pocket right above the velcro patch area. If you’re unfamiliar with the MOLLE (Modular Lightweight Load-carrying Equipment) system, it might be confusing seeing all the webbing on this bag. Those are basically attachment points for aftermarket MOLLE bags, pouches, etc. Bummed there’s no water bottle pouch on this bag? Simple get a MOLLE water bottle holder, don’t need the water bottle holder? Take it off. That’s where the brilliance of this bag shines. You can customize it for whatever you need.

Thanks to the numerous tie down options, I was easily able to stow my rod onto my pack. This bag is like a faithful wing man in that it literally and metaphorically has your back.
I was working on a deck located on a hill side, carrying a tool box was kind of a pain and I’m not really a tool belt kind of guy, so I stashed my drills and bits into the Lite Speed and was able to traverse the slope with my tools.
The webbing works great for MOLLE packs and adds so much more to the feature set of this pack. Here I have a water bottle holder and small accessory pack securely attached to the bag, I can remove them when I don’t need them, and that’s damn near priceless.
The rear flap can flip down and has a pocket for stowing a tripod, engineering blueprints or even a Red Ryder carbine action two-hundred shot range model air rifle. Oooooooh!


There seems to be a division in tastes when it comes to “tactical” backpacks. Some feel all the velco, patches and webbing is overkill relegated to mall ninjas or doomsday preppers. With the TAD Litespeed you can deck it out aesthetically almost as much as you can functionally. If you want to put a Punisher skull morale patch, magazine molle pouches and a paracord fob on the zippers, go for it. I personally feel the bag in black has a more sophisticated appeal. I like to keep the exterior streamlined and with the prevalent selection of velcro patches available you can personalize the bag endlessly, and it’s pretty fun to do so. The quality materials make this bag stand out among similar bags, almost like a good paint job on a car. I definitely would have preferred an internal pouch on the sides as opposed to so much Pals webbing, but it does come in handy when swapping between a water bottle pouch, or a tripod sling.

I consider this bag first and foremost a tool, and like pointing out the aesthetics of a screwdriver, I find it a somewhat moot point. I think this bag looks awkward when it’s decked out in camo and molle attachments at the airport, however at the range or on the trail it suddenly becomes not just a pack, but a serious piece of indispensable armor.


At the end of the day, I’m convinced the TAD Fast Pack Litespeed can raise to almost any occasion thrown at it, although it will cost you a fair ransom to tweak the pack to your needs. The overbuilt construction present an extreme value that will definitely alleviate the cost of ownership for a bag that can easily replace several bags in your closet. The styling isn’t for everyone, but if you’re looking for a quality, versatile pack I can say this bag warrants a second and third look.
