There’s plenty of space to carry anything you need to – towels, shoes, smaller pieces of equipment, iPad, phone, water bottle… You name it, it can fit it. There are pockets for shoes, water bottle, and accessories, so everything you need is neat, nice, and organized.
You can carry it as a standard duffle or cross body, which makes life a lot easier and adds to how convenient the bag is.
There is one thing to keep in mind, however, and that’s the price. It’s decently high and, while the price may not shock someone used to buying designer fashion bags, you may be surprised if you’re not that someone. It’s an investment, for sure. However, it’s going to last you for years because its quality is exceptional.

What Are the Benefits of Functional Fitness Gym Bags?
Convenience
With many different compartments specifically designed for certain gym accessories, fitness gym bags provide a convenient way to store and access the equipment needed.
Alongside the big compartments, fitness gym bags also usually have small zip pockets, providing a way to store smaller items such as money, phones, and hair accessories.
Portability
With their shoulder straps and/ or carry handles, functional fitness gym bags provide an excellent method of moving all your favorite gym gear without any hassle.
Versatility
Whilst fitness gym bags are designed for functional fitness, they can also be used for other sports or normal weightlifting. With the range of compartment sizes, they can store different shoes, jackets, or bigger sports equipment if you need them.
Protection
Most functional fitness bags are made with water resistant material, protecting the accessories inside from water. With their padded compartments, the bags also help to increase the life expectancy of the accessories that may wear down with repeated contact.
Weight distribution
The built-in carry handles and/or bag straps help to evenly distribute the weight of each accessory across your shoulders or using your arms. The weight of each accessory individually would feel much heavier and be a lot harder to carry compared to using a gym bag.

When Do You Need a Functional Fitness Gym Bag?
Fitness gym bags are needed by athletes from beginner to elite level looking to perform a range of gym exercises that include fitness movements.
With most compound and functional movements benefiting from the use of accessories, normal gym goers and functional fitness athletes need a convenient way to store and transport the necessary lifting accessories.
Gym accessories that can be stored in a suitable gym bag include:
- Lifting belts
- Lifting straps
- Knee sleeves
- Gym apparel
- Lifting shoes
- Lifting tape
- Resistance bands
- Sports towels
What to Look For in Functional Fitness Gym Bags?
Size
Even the best quality gyms like to save space by using smaller gym lockers. If you need to keep your bag secure when you're not using it, you may find it harder to fit bigger, more rigid bags into the locker space.
If you have a regular gym that you plan to use for the foreseeable future, check the locker size and compare it to the size and shape of the fitness bags you're considering buying.
To check if the gym bag is the correct size for all your functional fitness gear, make a list of everything you need to carry and factor in the possible additions you’ll make as you continue your fitness journey.
Material
Before purchasing a gym bag for fitness, make sure to check the interior and exterior materials. When considering the bag material, the two most important factors are the thickness and material used.
Whilst thicker bags tend to be more rigid and durable, the added bulk may make the bag less comfortable to carry around and harder to store and move around. The right thickness for you depends on what you're using the bag for and where you will be storing it.
Alongside thickness, you should check whether the bag is water resistant. If you're taking your bag from your car to the gym this might not be much of an issue, but if you plan to carry it outside for long periods, the material needs to be waterproof. Nylon and polyester are both excellent waterproof bag materials if you need to take your bag outside.
Variation of Pockets
One of the main uses of a gym bag is to provide convenient pockets to store a variety of functional fitness gear. With shoes, towels, lifting straps, sleeves, and belts needing to be stored, the bag needs to have pockets that can store each piece correctly.
Pockets providing shoe compartments, mesh areas for wet clothes, external water bottle holders, padded areas, and smaller zip pouches all make excellent gym bag pocket options.

Multifunctionality
Multifunctionality refers to how suitable the bag is for performing several functions. A good fitness gym bag needs to be easy to store and accessible, comfortable to carry around using different handle options, and function as an indoor or outdoor bag depending on your use.
Price/Quality
As with most gym equipment, you need to consider both the price and quality before making a purchase. In terms of quality, look for a bag that’s made of durable material designed to last. Consider durability vs functionality and compare that to the total cost. If you have a budget to stick to, consider the budget-friendly bag option I’ve reviewed above.
Color Palette
Whilst color isn't as important as the factors I've discussed above, it's still something to bear in mind. If you're taking your bag to the office, you might want to go for a more suitable color to match your work attire. If you want the bag to match your functional fitness apparel, check the most common color in your wardrobe and go with that.
