Odor Proof Bags for Backpacking: A Fresh Look At Odorless Travel

Written by Jessica Bayne

Camping and outdoors adventuring takes the wanderer off the beaten track, and into the territory of wild things. This is the whole point, of course. To remove yourself from the built-up environment, and sync your body to the calmness of nature.

Calmness, however, requires that the conditions are reasonably safe and that the supplies, especially food and water, remain intact, as these are not easy to replace if you are 3 days away from civilization. Therefore, it is highly recommended to include odor proof bags for backpacking on your hiking trip.

Having a campsite haunted by nocturnal beasts seeking to rummage through edibles not only poses a threat to the level of supplies that remain but more importantly becomes a danger to the people, as these beasts are often wild animals, the most common thief being bears. Definitely not something you should invite closer.

While it is extremely important to keep safe and vigilant, it is also important to pay close attention to the well-being of the environment you have entered. Out in the true wilderness, there may not be facilities such as dustbins to make it easy to dispose of unwanted trash.

Lugging around the trash can be an unpleasant experience, as some items may start to develop an unpleasant odor. Odor proof bags for backpacking can assist with both of these challenges and greatly improve the ability of the backpackers to keep their food safe, themselves safe, and the environment safe.

Features to consider

The common shortfalls of odor free bags tend not only to be their odor-stopping abilities, but also their tendency to burst at the seams, and their closing mechanisms to break.


A great feature to look for when choosing an odor free bag, is something made out of durable material, such as nylon or polyethylene terephthalate (PET or PETE), which will safely seal in the air and moisture contained in the bag, without transferring any dangerous chemicals into its contents, ensuring that the bad can be used for food storage too.

Products that are marketed as odor proof but are made from polyethylene (PE) will be ineffective, as they do not prohibit air and moisture from escaping, which will not prohibit odors from escaping either.


Good quality bags will also be water, and moisture proof, air-transference proof and also completely sealable. These traits are what will make a bag hold its odor inside. If air or water molecules are able to pass through an item, they will carry the odor with them.


They should be reusable, durable, and puncture resistant. Reusable products will ensure that you only need to purchase them once, and after each use they can be cleaned and should hold no odor relating to the contents previously held inside.

A puncture will allow for air and moisture to travel, which will mean odors are also able to travel, ensuring that your odor proof bags are durable will help to prevent punctures and tears.


There is a great variety of different odor-proof bags available, some of them even come in backpack models that are lined with aluminum. Aluminum is effective in controlling the movement of air and moisture, and these are carriers of odor. If a sealant is able to prevent air and moisture from moving, it will prevent odors from traveling.


Different shapes and types of bags or canisters and boxes will suit various uses. Some bags are similar to Ziploc freezer bags, and can be disposed of fairly easily. Some bags are more like toiletry bags, with zips, and can be washed and reused for years to come.

FDA approved

Bags made using plastic, should be made using medical grade material that is FDA approved. Often times these bags are great for storing food. To avoid a toxic or harmful substance from being shed onto the food, the FDA can examine and approve of the materials used in manufacturing the odor proof bag.

Product reviews

With all of that being said, here are a few of the top-rated products in the market.

Smelly Proof Bags

The seal is tight and reliable, provided the user takes the time to ensure it is properly done.

The zip seal tends to fail quite easily, and each bag seems to last for around 20 uses each, before the Ziploc mechanism no longer functions at its best. The sliding mechanism can also fall apart quite easily, perhaps because of the glue that was used. If the users treat the sliding mechanism with care, it should last a decent amount of time, though.

These are an improvement on ordinary Ziploc bags, keeping a lot of the odor contained, but they are not completely odor proof. The variety of sizes that this product is offered in makes it great to use for a variety of things, from storing wet rags to food or medical supplies, while being easy to carry and convenient to use.

Some of the bags are cheaper and lighter, which makes them great to use a few times and then replace, while others are very pricey, but should last you at least a few years.
