Men’s Merino Wool Base Layer Tops FAQs

Q: What is a base layer top?

A: A base layer top is a foundational garment designed to be worn next to the skin, optimizing moisture management, warmth, and comfort in various conditions. It's essential for layering in outdoor activities.

Q: How should a base layer top fit?

A: A base layer top should fit snugly without restricting movement, acting as a second skin to efficiently manage moisture and maintain body temperature. It should not be too tight or too loose.

Q: Do you wear a shirt under a base layer?

A: Typically, you don't wear a shirt under a base layer top as it's designed to be the first layer in contact with your skin. Adding a layer underneath can hinder quick drying properties and thermal efficiency.
