The Adidas Defender III uses polyester for the outer material. Commonly, we see the outer of a gym bag made of nylon. Polyester is an excellent option as it breathes a bit better and it is simple to care for. Additionally, it gives you good durability so you won't have to worry about it falling apart quickly.

Most gym bags are put together fairly simply. The Adidas Defender III is too. You won't be looking at a whole bunch of different materials in the construction. This makes it easier to care for and honestly, sometimes simple is best.

The only other real materials that you're going to come into contact with what this item are the zippers, plastic clasps, and velcro. All of the pockets are closed with zippers that are of decent quality. There is one piece of velcro that is used to secure the two smaller carrying handles together. The plastic clasps are used to hold the shoulder strap on and are of decent quality, as well.

When your fight gear is organized it can get you to your training session more quickly. In addition, it won't be frustrating when you're trying to find certain items.

Obviously, there is a large compartment in the center. This is where the bulk of your items are going to go. Due to the fact that there are different size options in this model, you will be able to find one with a compartment large enough to hold all of your pieces of sparring gear. This includes things like your shin guards, headgear, shoes, and gloves.

There are also a couple of smaller pockets. The smallest is located on the front of the bag and it's excellent for housing options like your keys, cell phone, mouth guard case, or hand wraps. There are also pockets located at each end of the Adidas Defender III.


As noted, you'll have a few different size options when you decide to go with the Adidas Defender III gym bag. This can make finding the perfect fit for your routine simple. We do not frequently see so many size options available. Most brands only off of one.

You will have your choice from small, medium, or large. It is twenty and a half inches long which is smaller than a classic sized duffel. You are looking at a width of almost twelve inches and a height of just over eleven inches. These are both fairly close to classic sizing.

The medium, obviously, is going to give you a bit more room. This option has a length of twenty-four inches which is the standard measurement for a classic sized bag. It has a width of thirteen inches and a height of twelve inches. These are also the average measurements for a standard duffel.

The width and height of the Adidas Defender III are also fairly large. The width comes in at thirteen and a half inches and the hight measures up at a whopping fifteen inches.


You won't actually end up getting a decent level of breathability when you decide to go with the Adidas Defender III. It does not have mesh panels built into it, however, it is made from a relatively breathable material. Polyester does tend to breathe better than nylon.

With that being said, you will still likely need to empty this gear bag out after each use to ensure that your items dry completely before you need them again. You may also find that you need to combat foul odors by using a deodorizing product with this bag. Some people, that don't have exceptionally sweaty routines, won't have to worry about this.

The more breathable your bag is. the less maintenance you're going to have to do.

Overall, customers are not complaining about the fact that this item Lacks breathability.


There are really only two different styles of gym bags. Basically, you get to choose from a duffel bag or a backpack. They both have advantages and we'll fit into different routines better than the other.

Obviously, the Adidas Defender III is styled like a traditional duffle bag. You are looking at one large compartment and some other pockets located on the sides in the front. This is absolutely what we expect to see in duffle bags.

This style of bag is best suited for those of you that have a large variety of gear and equipment to carry to and from the gym. When you need to have space for things like your headgear, water bottles, gloves, shoes, pre-workout drinks, and other items a backpack simply isn't going to cut it.


Let's face it, durability is one of the bigger aspects when we start figuring out if a product fits our routine or not. Most people using the Adidas Defender III are getting excellent durability from it. It does not break down quickly. Polyester is truly a strong material that can take quite a bit of abuse before breaking down.

Consumers have noted that there are some issues with the durability of the zippers. It is important to note that not everyone is complaining about this and we have only seen it crop up a few times. If you over pack your bag you may find that these zippers are not up to the challenge and break open. This could make some of your pockets unusable.

The only real complaint we've seen about the Adidas Defender III is in regards to its durability. There have been a couple of notes of consumers having durability issues, however, this appears to be a fluke. In addition, if you do run into trouble simply, contact Adidas and they'll do what they can to make it right.


Consumers love the fact that the Adidas Defender III comes in such a good variety of sizes. Depending on your stature, finding a bag that can actually have all of your sparring gear and other pieces of equipment can be difficult. So, as you can see, having some option in size means you'll be able to easily find what you need to fit your routine.

Another facet that consumers are really smitten with is the fact that they offer so many colors.

Regardless of what size you decide to go with you'll certainly be able to find the Adidas Defender III in a color that you truly love.

In addition, this can be very frustrating. Having the ability to separate your small items from your large items is a pretty big advantage that most consumers truly love.


The disadvantages that are associated with the Adidas Defender III are pretty minimal. Customers truly are happy with the overall construction and design of this gym bag. Even though there are very few negatives there are a couple of noises that need to be discussed when you are deciding whether or not this is the bag you want.

One thing that has been consistently complained about is that where the shoulder strap attaches to the bag gets very squeaky. This is very annoying and it doesn't stop with added use. The plastic simply rubs and makes this very irritating sound.
