Things to Keep in Mind Before Making a Buying Decision 

If you don’t know what to wear under your fishing waders, there’s nothing to fret about as here are some top factors to consider when shopping for the right product. 


It’s never a good idea to sacrifice your comfort and flexibility. Sure, you might think you’re wearing top-notch waders, but it won’t matter if you don’t know what to wear underneath them. This is why your priority must always be to buy something that offers the ultimate comfort to have a more relaxing and exciting experience. 

Time in the Water

You will start to feel colder depending on the amount of time you spend standing in the water. It doesn’t matter if the weather is hot, your body will gradually begin to dissipate heat. And this is where your legs will start going numb. So, if you’re going on a long fly fishing trip, it is important to dress in a couple of layers rather than packing light. You need to eliminate the risk of feeling cold. 


If you’re a novice fly fisher, chances are you don’t know what wicking means. Wicking is simply the capability of a material to eliminate moisture and sweat build-up. Even during winter, if you’re out on a long fishing adventure, you will begin to sweat. Thus, when you talk about what to wear under waders, the answer is simple – don’t wear anything that is overly warm, like a sweater!

Irrespective of the weather, it is important to go for materials that are designed to help get rid of moisture, allowing you to stay comfortable and sweat-free throughout your fishing excursion.

Warmth and Overall Temperature

When it comes to what to wear under waders, the most important factor to consider will be the weather. You see, you won’t enjoy fishing as much standing in the blistering heat. Similarly, you’d be constantly shivering in colder weather. 

Just as how it is unreasonable to wear shorts in winter, wearing multiple layers under your waders in a hotter climate is going to zap the energy right out of you. So, the type of clothing you wear beneath your waders is also mainly going to depend on the weather conditions during your fishing trip.

Materials To Consider

Apart from comfortability, what you wear under waders should appropriately fit you and the material should be elastic enough for you to freely move. Moreover, the clothing item should also feature wicking materials so that any moisture accumulation can be quickly evaporated. In light of this, some of the best materials to stick to include nylon, wool, and polyester.  

Materials You Should Never Wear Beneath Your Waders

One of the worst materials to wear under waders is cotton. Why? Well, cotton does not have very good moisture wicking capabilities. This means your clothes are going to retain your sweat and moisture and you will feel wet and cold. This can be extremely irritating and abrasive, especially considering the fact you’re going to be standing in the water. Let’s assume that you’re fishing, and your waders have a tiny hole in them, if you’re wearing cotton pants, your skin will soon start to itch and chaff.  

Best Wader Options Depending on the Weather 

Stockingfoot Waders 

Stockingfoot waders can be an excellent choice if you’re planning to go on long fishing trips during hotter months. The best reason why anglers choose this option is that Stockingfoot waders are designed to be considerably lighter with bare minimum bulk compared to traditional options such as bootfoot waders. With layering underneath you can greatly influence how warm or cold you’ll feel. Hence, if you want to fish your stocking foot waders all year round, just wear a couple of extra layers or thicker layers during winter time.

Neoprene Waders

Neoprene waders are ideal for fishing in colder months. They’re designed with heat-retention materials and are considerably less breathable compared to stockingfoot waders as they’re made for withstanding harsh winter winds. So, if you’re planning to go fishing during winter, it is important to wear something that has wicking properties.

Bottom Line on What to Wear under Waders

So there you have it. A comprehensive list of some of the best products to wear under waders. However, it is equally important to keep in mind that the product you select should always be in line with your preferences and requirements. Moreover, the combination of upper and lower clothing items you choose will also depend on the type of weather you will be fishing in.


Do you wear clothes under chest waders?

Modern day quality stockingfoot waders are breathable. To take advantage of their breathability you should wear moisture-wicking clothing that can effectively remove moisture from your skin. Recommended materials are polyester and merino wool.

Can you wear jeans in waders?

Technically you can but we don’t recommend wearing jeans under waders since they are made of cotton. You should look for moisture wicking materials such as merino wool or polyester. Cotton is not moisture wicking and you’ll be wet (and cold) under in your waders.

What should I wear under waders on a hot day?

The most important feature on a hot day is for your clothes to be moisture wicking. Pick a fabric that has these qualities such as polyester or a light merino fabric. Don’t go for cotton since cotton is very bad at moisture wicking and the sweat won’t be removed from your skin.
