Gym Bag

Most people have their own favorite bag whether it was given by someone special or because it is so good that you won’t be able to leave the house without carrying them. We love bags as they ease your activity by keeping all of our necessary items in a compact but convenient storage thus, we can bring them anywhere. The options however, is highly subjective for the best bag will be able to accommodate to your needs the best, be it for the storage or easy carry.

Your activity will prominently decide which bag to go for and it is great to choose from those made for our certain application such as suitcase for a travel that require less transits or adventure and backpack for easy carry and frequent movement during the journey. For daily need, a regular daypack should fit all of our gear including gadgets, water bottle, or even additional clothing. If you are here then it means gym bag is what you look for and before shopping, here are some factors to consider:

  • Gym Bag and Storage

The first point we have to decide when buying almost any bag meant to carry items is the storage space because it is an integral part of a bag and affects what you can fit inside the compartment. The bigger doesn’t always mean better since there is no need to carry a huge bag with only a little items inside. Decide what you want to carry everyday and the size of your gym locker to make sure we are getting a perfectly sized bag.

  • Gym Bag and Organizer

This is our second point when checking out a new bag because a good bag will make sure the items inside are not cluttered together especially for gym bags which most often will be stuffed with sweaty clothes or shoes. Make sure to find the model with separate rooms to place dirty stuff so it will not affect your clean clothes if you bring any. Small storages are also great when you have to take and put items quickly.

  • Gym Bag and Materials

Gym bags need to be durable for its load and all of us want the one that can last so the material options you will often find are either cotton canvas or nylon specifically those from inexpensive brands. If you are interested in having a leather bag, keep in mind that this material will absorb pungent scents and not advisable to be a gym bag material. Common fabric like nylon is durable and easy to wash when needed to keep it pleasantly fresh.

About Under Armour Undeniable 3.0 and 4.0

The good gym bag used by your gym buddy may look attractive but make sure to shop based on your own needs because our bag and activities will not always be the same. Following those steps will save much time selecting from the vast choices but if you already have a favorite brand, checking out their collection will be faster especially if they are a huge name with tons of models. In addition we also want to mention budget since it is not worth to spend a fortune just to get a reliable bag.

Among those many great brands out there, Under Armour is one of the best choices to look at not only because they are a very popular sport products manufacturer but also because of their good quality products. We love many of their running shoes as well as gym wear and they also carry a nice amount of gym bags. They offer varying carrying systems if you prefer those we can carry with hand, with sling strap, or regular shoulder strap.

For gym goers that spend an amount of time everyday exercising and getting fit, Under Armour Undeniable 3.0 and 4.0 will be a very promising option. These duffel bags are ideal for daily use and they are sized perfectly as well to make sure we do not end up with a shape-less bag filled with dirty gym clothes. These brothers are however, very similar, making it a bit difficult to decide about which model we would go for and in general, you will be satisfied with either of them.

What you will get in the first bag will also present in the second option with all of the specifications staying similar to each other. Seeing Undeniable 4.0 as an improvement is not correct because it is more like another version of the Undeniable 3.0 with some people preferring the former more. What we love the most from these gym bags is the material choices, style, as well as convenient carrying system and their organizing part, making them one of the best gym bags in the market.

Under Armour Undeniable 3.0 and 4.0 Design

The first part we see in any bag including a gym bag is their look and while it does sound unimportant, we do pay attention to how good they look. Under Armour Undeniable 3.0 and 4.0 are not a very fancy bag but we are liking their simplistic design because there are only parts you will need here. The overall look is sporty and universal enough to be used by both men and women. We also like their color options since they are very stylish yet still sporty.

The shade options are varying such as blue, black, pink, and some with color combinations or details. As for the size collection, there are several to choose from extra small to extra-large depending on which will fit your gym needs better. Not only for gym application in fact, many of us bring the bag while travelling as well due to the material durability and wide storage. Read also: Hikpro Vs Outlander.

Under Armour Undeniable 3.0 and 4.0 Main Compartment

Moving further, let’s check their compartment first and here you will see one main room which is big enough to put various items depending on the size option itself. For the medium size we can stuff a water bottle, some gym clothes like hoodie and shirt as well as shoes. This room has no separating flap or organizer but it makes filling and taking out items easy. The rectangle shape makes the bag convenient to put but also maximizes the storage efficiency. 

Beside this main compartment, you will also get another pocket inside and it is the size of a smartphone but a bit deeper. This small pocket is nice when you have to put something like a small wallet, keys, or phones for it can be easier to locate but the difference is Undeniable 3.0 will feature a zipper here in which the latter only have a concealed opening.

Under Armour Undeniable 3.0 and 4.0 External Compartment

Not only the main compartment, we also love the fact that you can get several external organizers with Under Armour Undeniable 3.0 and 4.0 which is slightly different. First we have a big pocket at the front to put smaller items and in the latter you will also find an additional smaller pocket in the middle that we often used to store keys, pens, or earphones and watch. Moving to the side there is a shoe compartment on the left.

But, this room is only ideal to keep standard shoe size or size 11 since bigger shoes may struggle to perfectly snug inside. On the other side there is this flexible mesh pocket to keep any items that you will access quickly yet, most people tend to ignore it for some reasons.

Under Armour Undeniable 3.0 and 4.0 Straps

The last part we want to mention is their carrying system and here both of them are identical to each other. The basic mode of duffel bag is hand carry and there is a padding on the top side to ease the carrying system. They are durable and will be able to sustain quite a weight yet, if you will be walking further, we can use the shoulder strap. This shoulder strap has adjustable padding to provide some cushioning.

Since this shoulder strap can get annoying if left unused, Undeniable 3.0 will allow you to remove it but this option strangely only exists in the medium size. There is also news that Under Armour removed the shoulder strap pad on this 4.0 bag for uncertain reasons.

Under Armour Undeniable 3.0 vs 4.0

Both of these bags are ideal for anyone who will be going to the gym frequently and side by side they are also the same but, you will notice that Undeniable 4.0 doesn’t have the removable shoulder strap option and this model also doesn’t have a zipper in its small pocket inside the main room. While Undeniable 3.0 has the removable shoulder strap, this feature is only present in medium size and this model also doesn’t have a smaller front pocket.

All in all both gym bags are amazing and you can go with either of them but if we are to choose, we do like the Undeniable 3.0 especially for the removable shoulder strap and its smaller pocket with zipper inside.
