What Is A Running Base Layer?
A running base layer is a top worn for running that regulates the temperature of the body in any season. In the summer months and on hotter days, a running base layer acts as a regulator, wicking away sweat from the skin.
As well as this, you can wear a base layer for running in cold weather throughout winter, as it will act as a heat preserve and fit like a second skin. To achieve optimal performance from your running base layer, it's a good idea to opt for one that is tight fitting and comfortable, so you can wear it underneath any running garments without irritation.

Why Is Merino Wool A Good Base Layer?
Merino wool is a fiber that is harvested from Merino sheep, and as you will have found throughout the list, it is something that is included in only the best running base layers. It is a widely popular component to base layers due to its many desirable qualities, such as:
- UV protection
And a key feature, odor resistance. Due to the ability of Merino wool being able to withstand moisture naturally, odor is kept at bay throughout exercise and can be helpful for reducing wash loads and getting more wear from your base layer.
How Tight Should My Base Layer Be?
Your base layer should be relatively tight and snug but not so much that it restricts movement. If you’re looking for a base layer to keep you warm, you want a top that fits close to the skin to trap in heat.
You should be able to move freely yet have a ‘second-skin’ feeling from your base layer. That is why it is important to have a good material that has stretch and softness to prevent any stiffness.
We recommend that you go for your typical size as too small may feel restrictive and too big will not be useful for temperature regulation.
