First on our review list is the Skunk Urban Backpack. For the hiking enthusiast in search of a favorite everyday companion, this urban pack is likely to tickle your fancy. It has a nice design and is packed with the finest smell proofing features.

Just like any odor absorbent backpack that is worth buying, this one has a carbon filter and thermal lining. It also comes with several layers that protect the interiors and their contents from spills and rain.

This makes it an all-weather bag because it is stress-free to maintain an entirely odorless environment even during unfavorable weather.

One of the unique features is that the interiors of the bag are also lined with quality anti-smell retaining filters.

The carbon filtration technology used here works effectively enough to allow you to hike with one bag and throw your shoes, sweatsuits, and other clothes inside.

Apart from the convenient side pockets, you will find two main compartments inside with zipper pockets on the walls of each section. They serve as perfect secret compartments where you can keep your personal items more discreetly.

The waterproof zippers make this bag worth every dime that you spend on it. In any case, an inferior zipping system makes a backpack inferior, irrespective of the quality of its carbon lining. The zips close tightly, ensuring that odors cannot escape.

Combination locks prevent nosy people from accessing the contents in your bag.

If you like to keep your stink affairs private, this is a feature you will find to be helpful.

Even the stink from abused sneakers remains well concealed. The layers of active carbon can effectively filter out the smells, allowing you to travel with your foul-smelling gear in a very discreet manner.

Features to Consider Before Buying an Odor Proof Backpack

When it comes to buying a backpack, you should do more than just pick the first one you can find. There are a plethora of crucial aspects you must consider to find a high-quality rucksack that can play the intended roles.

Is the Bag Actually Smell Proof?

The whole idea of purchasing this particular kind of bag is for you to have better peace of mind when walking around with your stink bombs; whether a specific brand provides truly odor-proof bags or not is an aspect that must not escape your attention.

Odor proof bags differ in numerous major and minor aspects. Do not be fooled by marketing gimmicks, where all manufacturers claim to produce the ideal bags.

In this case, getting the right product the first time is essential lest you want to risk embarrassing yourself during the most inconvenient of times.

Some research and patience are necessary before you select the bag to purchase. It is in your best interest to confirm that your bag of choice has a quality lining made of a smell resistant material.

Additionally, check out the reviews of other people with first-hand experience in using the bag brand that has your attention.


The material used in the crafting of a bag will make it easy for you to establish whether it is odor-proof or not.

As we mentioned earlier, activated carbon is the secret behind how the odor-proof backpacks work. Even so, other equally good technologies can be used to make a rucksack odor proof. For instance, aluminum works equally as effectively in locking in the stink.

Aluminum can serve the purpose of activated carbon in two main ways. To begin with, it is oil-based, and this means it can lock in the unpleasant smell way better than those plastic baggies.

It is better to use aluminum to dodge possible problems. Also, it is less porous than plastic or fabric and can provide more dependable smell-proof solutions.

In case you are in a rush to hide your smelly socks, and you do not have the right bag, just wrap them in several layers of quality aluminum foil. This will provide temporary solutions.

Design and Quality

It is not every day that you hit the markets in search of the best smell proof bag. For this reason, it is common understanding to consider the quality of a bag before betting your money on it.

To get a quality rucksack, you need to consider more than just the features of a bag and the materials used in making it. You should also take note of its style and generally make sure that a specific product can hold up to consistent use without failing.

The need to consider the style of a bag cannot be emphasized enough. Even if you find a product that is truly smell-proof, this will not be enough as long as it does not look like regular bags. Any design that draws unwarranted attention is not worth it.

Still on matters of design, see to it that your gym clothes, towels, and shoes can lay inside the bag in a well-organized manner. Additionally, a good rucksack will be comfortable to wear and will not be ridiculously heavy.


A smell resistance backpack is of no use if it cannot hold up to at least one year of everyday use.

Here’s what I mean.

You must put into account the durability of the entire bag, and most importantly, the odor-proof mechanism. If the aluminum or activated carbon begins to wear out, then your backpack is just as good as any regular rucksack.

This is irrespective of whether its exteriors are equally as worn out or they are in a pristine state.

Zipping System

Naturally, all rucksacks have zippers. This includes regular ones and even odor-proof bags. This is not the point I’m driving at.

Let me explain; if you are out in search of the best odor-proof weed backpack, you ought to pay close attention to how the zipping system closes.

If it fails to close properly, this means it will allow odors to escape through the holes and your expensive bag will not play its role.


Just like when buying any other merchandise, you should consider your needs and goals before purchasing the bag. Depending on how much junk you intend to be carrying at any one point, you need a bag that is spacious enough.

People are created differently. While some carry only a change of clothes when heading to the gym, others will want to have their hand towels, body towels, and runners for a generally better experience.

Before money changes hands, decide how much of your gear should fit into your bag at any given time. Based on this, it will be much easier to choose a rucksack of the perfect size.

Be sure to consider the number of compartments you need and how big the main compartment ought to be.


Times are hard, and the cost is an aspect that hardly escapes the minds of most people. Before you begin your hunt for the best product, create a budget, and define how much cash you are willing and able to spend on the purchase.

Establishing a budget will help you narrow down your options and focus on backpacks that are within your financial means. This will save you from the effort and time needed to go through every single odor-proof rucksack available in the market.

Benefits of Using a Smell Proof Backpack

A top-quality smell-proof rucksack will play its primary role, which is concealing the smell of your contents.

However, there are more than a few benefits you stand to enjoy once you have invested in the bag. These perks include:

Avoid Unwanted Guests

Are you going on camping?

You must have food with you and some of them are very smelly and can attract bears or other animals. If you put the foods in your smell proof backpack with lock, you can relax as no animal will get the smell of the foods.

Stress-Free Commuting

Simply because the stink of your gym clothes is natural does not mean that it will not offend other people.

Keeping it concealed is a relief, especially if you intend to carry your contents when visiting public areas. A quality bag can save you from the self-doubt that comes with knowing you are carrying around some stinky stuff.

Save Money

Purchasing a smell proof rucksack is a one-time investment. This is more so the case if you opt for a quality bag.

Airtight baggies can, on the other hand, suffice, although they are not durable or even reusable. They are also not a practical option when carrying plenty of gear, including your gym shoes and towel.

Avoid Unwarranted Attention

When accessing public buildings, you can relax because nobody will be able to smell the contents of your stink sack.

In case you are expecting guests in your crib, you do not need to freak out and possibly try creepy means of hiding your smelly socks.

Simply throwing all stinky items in your bag can save you from unnecessary embarrassment.

How Do Smell Proof Backpacks Work?

The science behind how the backpacks function is not as intricate as many may assume. These bags are a relatively new concept that most people are yet to get well-acquainted with. Here is what you need to know.

For the hiker that loves to travel, the chances are that you are already aware that your regular bag cannot conceal the smell of your sweaty gear.

Even if you have heard about odorless bags, these products are not highly advertised, so finding one can be a bit challenging.

External Features

The external features of a smell proof bag will not be so different from those of a regular backpack. After all, the whole idea is for you to maintain a low-key presence even as you carry around your stinky stuff.

Nevertheless, the truth is that there are other alternatives you can explore when seeking to commute with your used gym gear.

You can throw the junk in your car and risk messing your ride’s air quality. Also, you can choose to use smell proof baggies, which eventually leak out the smell after repeated use.

Internal Features

The backpacks come with a lining made from carbon filter. This is the secret behind their ability to keep even strong sweat smells well concealed. A carbon filter is a powerful agent that prevents any stink from leaving the bag.

In a nutshell, your smart bag is smell proof because it contains an activated charcoal filter (AFC) lining. What happens is that the activated carbon charcoal is treated and this increases its surface area.

When in need of more permanent and practical solutions, it makes better sense to invest in a durable, odor absorbent bag. It is big enough to carry your gym tracksuit, shoes, and even your towel and other accessories you carry around.

How Does the Carbon Filter Lining work?

Carbon is one of the most porous substances you can find. It chemically fixes the particles of stink into its pores. This is a property that makes the carbon lining of the bag quite effective in absorbing smells.

In layman’s language, the activated carbon filter acts as a vacuum. It sucks up the smelly particles in the air that passes through it. The molecules of odors that get into contact with AFC activated charcoal filter within your bag instantly get trapped by the carbon pores.

Listen closely; a quality bag will conceal the smell so well that the greatest risk you face is forgetting where you placed your dirty socks. These bags have been tested within controlled settings, and it is clear that they work.

Difference between a Regular and a Smell Proof Backpack

Down below, we talked about the differences in between the two in plain words;

Smell Proof

From a distance, the backpack will look like a regular bag. It does not have any distinct external features that set it apart. This means that as you walk around with the rucksack, nobody will have reason to suspect you are carrying any kind of stinky stuff.

As mentioned earlier, what makes this unique bag different is its carbon filter lining. It is also worth mentioning that the odor-proof bag has a relatively tighter zipping system that also plays a role in preventing smells from leaking out.


With a regular bag, irrespective of how well constructed it is, the smell of your sweaty gym clothes will leak out. This is any fashionable person’s worst nightmare, especially in this era where good grooming and matters of personal hygiene are taken very seriously.

The AFC in a smell proof bag traps the foul smells, including the stronger sweat odor. When the bag is emptied, nobody will suspect it has ever carried stinky gear in it!

Top Brands that Make the Best Smell Proof Backpacks

There is a whole world of odor-proof bags out there. However, not all of them are well crafted, comfortable, and 100% smell proof. You owe yourself the favor of giving priority to the bags we have mentioned above.

Your needs and goals will play the leading role in dictating which one will be the best odor proof backpack for you.

If you often carry around a gym or hiking gear, for instance, big and spacious bags will make better sense for you. In this case, we recommend the Funk Fighter backpack or the Skunk Backpack Rogue. You can also use these as hiking backpacks.

Finding a bag that appeals to your needs is excellent. It is equally important to finding one that rhymes well with your sense of style. Even though all the bags, as mentioned earlier, have a unique design, certain brands genuinely stand out.

The Dime Bags’ odor-proof backpacks and Revelry Supply’s Escort backpack, for instance, are superb for people with a heightened sense of fashion.

Depending on the public areas you often access, you may find a bag with a combination lock to be more appealing. Bags such as the Skunk Nomad Skaters backpack offer extra security. Your contents remain private and safe as long as you are the only one with the lock code.

When your primary mode of transport is your skateboard, some bags have skate straps where you can tie your board or even your yoga mat.

You can also find great designs like the Dime Bags Skatepack Odor Proof Backpack that has both a removable pouch and a secret compartment.

Our recommendations consist of bags that differ in style, size, and features. The only thing that makes them alike is that they are 100% smell proof.

Frequently Asked Questions

Below we have some of the commonly asked queries regarding smell-proof backpacks:

Is a smell proof bag really smell proof?

Yes, they are. Even with your stinky socks and gym clothes inside the bag, their smell will remain well concealed as long as you invest in a top-quality rucksack.

Why do the bags have a mesh liner?

For the bag to be genuinely odor-proof, the smell needs to be exposed directly to the carbon fiber. The mesh ensures that this crucial process is not obstructed.

Can I wash my smell proof bag?

It is best to protect the interiors of your bag from getting wet. Unfortunately, the lining of activated carbon fiber is not waterproof. When it gets wet, it clumps up and becomes useless.

Are the charcoal filters or liners removable? Can I replace them?

It is not possible to swap the carbon lining. However, there are ways to reactivate a smell proof bag. Just turn it inside out and place it in a dryer, over light heat, or under the sun for at least 10 minutes.

What is the care routine for odor-proof bags?

The most basic care routine is to always throw your stinky stuff in a protective bag before putting them in the odor-absorbent backpack.

You can use a ziplock bag for small stuff like socks or any other washable sack for larger items.

Final Words

Stinks are all around us. Whether you are carrying your hiking gear, your evidently abused running shoes, or any other stinky stuff, the best smell proof backpack can effectively conceal the unpleasant odors.
