Can Rain Cover Smell?

We’ve all been there. You’re out on a hike, in the middle of a downpour, and you pull out your rain cover only to be met with a wave of odor.

It’s an unfortunate reality of rain covers that they can develop a musty smell over time. But why does this happen? And is there anything you can do to prevent it?

Let’s take a closer look.

What Causes a Rain Cover to Smell?

There are a few reasons why rain covers can develop an unpleasant smell. The type of material the cover is made from, how long it’s been used, and where it’s stored can all contribute to musty odors.

Synthetic materials, like nylon or polyester, are more likely to hold onto moisture and bacteria than natural materials like cotton or wool. This means they’re more prone to developing smells over time.

In addition, the longer a rain cover is used, the more exposure it has to elements that can cause it to develop a musty odor.

If the cover isn’t washed regularly or if it’s stored in a damp or humid location, mold and mildew can start to grow—and that definitely won’t do any favors for the smell.

How to Prevent Your Rain Cover from Smelling Bad

The good news is that there are some things you can do to prevent your rain cover from developing an unpleasant odor. Washing it regularly with mild soap and water is a good place to start.

You should also make sure to allow the cover to dry completely before storing it away. Inspecting it regularly for signs of mold or mildew growth is also smart—if you spot anything suspicious, treat the area with mold and mildew remover right away.

Following these simple tips will help keep your rain cover smelling fresh for seasons to come.


No one wants their gear to stink—especially not while they’re out enjoying the great outdoors! Unfortunately, though, rain covers can sometimes develop musty odors over time.

The good news is that there are some things you can do to prevent this from happening. By washing your rain cover regularly and storing it properly, you can help keep it smelling fresh for seasons to come.
