5 Best Base Layers for Hiking (Our 2024 Review)

If you don’t have time to read the entire review and just want to find out what the Best Base Layers for Hiking is, then we recommend the MERIWOOL Men’s Base Layer as the best choice.

If you want to be comfortable and have fun while hiking, it’s vital you choose the right equipment. When it comes to clothes, never underestimate the importance of the base layer. It’ll be in direct contact with your skin so it has to be natural and soft.

That’s why I’d suggest base layers made of merino wool. They let your skin breathe and eliminate any unpleasant odors. That said, there are various factors you should consider when choosing the best base layer for hiking.

In this post, we’ve reviewed the Best Base Layers for Hiking. These are:

What Should You Pay Attention To?

A base layer is more than just another piece of clothing. The wrong choice could completely ruin your experience in the mountains.

You want a base layer that will keep you warm but at the same time wick well. Here’s a list of things you should have in mind when buying a base layer.

Temperature Control

When you’ve headed hiking, you can never be 100% sure what the temperature’s going to be.

That’s why the best base layer for hiking should keep you warm when temperatures are low but adapt to your body temperature when it gets warmer. Put simply, it should let your skin breathe naturally.

Moisture Wicking

This should be your No. 1 priority. Hiking is a physical activity that has many benefits but it’s also very demanding. Therefore, it’s normal for you to sweat. You need a material that dries quickly and wicks well.

There’s nothing worse than a change in the weather and having to continue hiking in wet clothes.

Merino wool is a good choice because it dries pretty well. Also, this material is odor resistant. In particular, Merino wool is much better than cotton or synthetics when it comes to eliminating unpleasant odors. It also has certain anti-bacterial properties.


Naturally, you need a base layer that’s easy to maintain. You should definitely opt for one that’s machine washable and dryable.

Delicate base layers might feel great on your skin, but what’s the point if they get ruined after a couple of washes? You should choose a base layer that’s easy to clean and made of durable material.


You’re going to spend a lot of time wearing a base layer, so you should choose the one that feels the most comfortable for you.

Most people like to wear a base layer that fits their body snugly, whilst others prefer to have a looser fit.

It’s important that the material doesn’t itch and irritate your skin. When it comes to softness, it’s down to personal choice in terms of material.

Best Base Layer for Hiking in Every Season: Woolx Explorer – Men’s Midweight Merino Wool Baselayer Top

<< Check Price on Amazon >>

Every experienced hiker knows that you need a base layer for every season. During winter expeditions, this model protects you from the cold. In warmer months it regulates your body temperature and lets your skin breathe. For that reason, it can be used both as a base or mid-layer, depending on the weather.

At the same time, this model is very warm and soft. It keeps you comfortable during long hours in the mountain and doesn’t affect your performance. It won’t cause itching or irritation, as some synthetic materials do. It’s easy to maintain and can be washed and dried in the machine. Most importantly: It won’t shrink!

The biggest advantage of this base layer is that it dries super quickly. It’s also odor resistant – but that’s not all. This model has special anti-microbial and anti-bacterial properties. This is very important because sometimes you won’t be able to wash your base layer as often as you want.

This model is somewhat longer than regular models. Some people find this ideal because it means they’ll finally get that extra few inches in the sleeves. This can be both an advantage or a downside, however, depending on what’re you looking for. That said, it’s perfect if you have long arms and torso and struggle to find the model that’d fit you.


  • Multipurpose
  • Quick-drying
  • Anti-microbial

This midweight long sleeve base layer is made of 100% New Zealand Merino wool. Like other base layers, it’s adaptable, temperature regulating, and wicking. All of which will keep you comfortable for hours. Moreover, this natural material dries before you even realize you were sweating.

New Zealand Merino wool is a very flexible material which means that this base layer won’t stretch out even after years of actively using it. However, this also means that this model isn’t as smooth as the other ones.

This model comes with thumb loops that make it extra practical. You may appreciate this feature if you’re irritated when your sleeves move every time you try to add another layer. And I know this happens often because most hikers wear multi-layer clothes. Also, they protect the more sensitive skin of your hands.

One thing that sets Merino 365 apart from the other models is that it’s sustainable and proven to be ethically produced. This makes it the best choice if you’re ethically conscious and care about the environment. If you want to be sure that the money you’ve given is a well spent, you should opt for this model.

As mentioned, the wool itself comes from New Zealand but the products are actually made in various parts of the world, in controlled conditions. The manufacturer guarantees that everyone who participates in the process of making your base layer will be fairly paid.

That may be the reason why this model has a slightly elevated price. If the price varies depending on the size you choose.


  • Ethically produced
  • Natural material
  • Temperature regulation
  • Doesn’t stretch out
  • It has thumb loops


  • Some models are pricey
