What is a Base Layer?

A base layer is the first layer of clothing that you put on when getting dressed for a hike, and it plays a vital role in keeping you comfortable and regulating your body temperature. You can add other layers on top of your base layer, such as a mid layer jumper or top, then a waterproof coat, if needed.

In this post, we’ll share our top picks for the best base layers for hiking, so that you can stay comfortable no matter what the weather conditions are.

What is the best fabric for a base layer?

When it comes to choosing the best fabric for a base layer, there are a few different options to choose from. One of the most popular choices is merino wool, which is a type of wool that is derived from merino sheep. Every year, Merino sheep shed their old, ultra-downy coats and grow new ones, making their wool a very renewable resource.

Merino wool keeps sheep warm in winter and cool in summer. When made into a fabric, it reacts to your body temperature, stopping you from getting both too hot or too cold.

Merino wool is an excellent choice for a base layer fabric because it is very soft and comfortable next to the skin. It is lightweight and breathable, and it has natural moisture-wicking properties that help to keep you dry and comfortable.

Another popular choice for a base layer fabric is synthetic fabrics such as polyester or nylon. These fabrics are typically less expensive than merino wool, and they are also lightweight and breathable. However, synthetic fabrics don’t have the same moisture-wicking properties as merino wool, so they may not be as effective at keeping you dry and comfortable during strenuous activities like hiking.

If you’re looking for the best base layer for hiking, look no further than merino wool. This natural fabric has a number of properties that make it ideal for outdoor activities. In addition to being breathable, it’s also naturally odour-resistant, so you won’t have to worry about sweat becoming smelly! It’s a lightweight and warm fabric, so you’ll be able to keep comfortable even in colder weather.

What are the different types of base layers?

When it comes to choosing a base layer, there are a few different options:

  • Long sleeve shirt – coverage for whole arms and torso.
  • Short sleeve shirt – coverage for upper arms and torso.
  • Base layer trousers/leggings – tight fitting, legging style trousers to provide warmth to hips, pelvic area and legs.

Depending on the weather conditions, you may prefer just partial, or full body coverage. No matter what kind of hike you’re planning, with our top picks, you’ll be prepared for anything Mother Nature throws your way.
