Loctote sent me three durable bags to test out. I will be reviewing the AntiTheft Sack 3L here, but you can also check out my reviews of the Cinch Pack and the Flak Sack II.

This bag is advertised as being small and protective. It is a bag that can be carried around in your hand or attached to a larger bag such as a backpack. So, is this a bag that will fit into my life?

Read on to find out what I thought of the AntiTheft Sack.

First Impressions

Just as the other two bags did, this bag comes shipped in an off-white bag that keeps everything safe and secure and packs it up nice and neat. I pulled the bag out, and it really was nice and small.

Checking out the bag for the first time, there was not really much to see. The strength of the bag is the size, and I can see it being used in place of a purse or wallet, especially where you need some extra security or protection.

It is also extremely light, and I can see myself using it when traveling. If I am on a long-haul flight or bus trip, I like to store my wallet and phone in the bag that I am carrying for extra comfort, and this would add some welcome security.

If you are going anywhere, taking little with you, but what you are taking is extremely valuable, then this is definitely a bag to check out.


  • Size: 12.5” x 8.5”
  • Capacity: 3 liters
  • Weight: 9 ounces


This bag is small, so what does it give you?


The material is lightweight, which is definitely needed in a bag this size, and it is also slash, tear, and abrasion resistant with an A4 cut level. Checking out this bag after checking out the Cinch Pack backpack; they look to be made from the same material.

The seams are also slash-resistant, and the one-piece design limits any weak points. The strap is slash-resistant, and this is what is used to lock the bag to something should you need to do that.

I decided to check out just how slash-resistant the material really was, so I took my utility knife with me and put the bag to the test.

As you can see, the material is solid and is definitely going to stop anyone from easily stealing your belongings.


As expected from first impressions of this bag, there is only one pocket inside, and I would not want any more, or it would become too crowded inside. The pocket is RFID blocking, so it protects anyone from scanning the interior, which makes it perfect for carrying your cards or a passport.

There is definitely enough room to carry everything that you would usually carry in your pockets or a small purse.


If you are looking at buying this bag, you are not looking for comfort here, but there is certainly nothing uncomfortable about it.

If you are carrying this bag around, there are three main ways to do so.

  1. You can put everything inside, cinch it, and carry it in your hand. That is perfectly doable, but you are not going to want to carry it around all day like that.
  2. You can cinch it and carry it by the strap after you have locked it. The strap is comfortable, and it makes the bag easy to hold.
  3. The third way to carry it is to lock your stuff inside and then place the small bag in a larger bag. It is small enough that it will fit in any backpack or medium+ bag.

How To Use

There are two ways to use this bag once it is secured, and both ways start with cinching and locking the bag.

If you pull on the strap, you will cinch the bag, and two metal looks will eventually become visible. Once you have that, you can lock the metal strap to the two looks with the brass combination lock.

The combination lock is set initially to 0-0-0, but it is simple to personalize the lock, and the instructions are included with each bag.

Once you have the bag cinched, you can carry the bag around by the looped strap. Of course, you do not need to lock the bag to carry it around and can just cinch it. This will leave you with a longer loop to carry, and that also works fine, but I have found that it is more comfortable when locked completely, and you may as well get what you pay for.

The second way to lock it is to wrap the strap around something before you lock it to the bag. This could be a metal pole or something of a similar size.



So, will I use this bag? I definitely will.

I am probably not going to use this bag as much as the other two, but I can definitely see the need for it. When traveling, I have never had my valuables stolen, but I have also never been in a car crash, and I still wear my seatbelt. With my wallet, phone, and keys in this bag, I am going to have an added sense of security, and it might even open up new experiences.
