A mid-layer shirt is a versatile piece of clothing that can be used year-round under your shell jacket for a variety of activities as well as for everyday wear. Wool and fleece are ideal materials for a mid-layer. This is because wool has good heat-insulating properties while also allowing the body to breathe and regulate temperature. Here, you will find functional and durable mid-layer shirts for men from well-known brands like Norrøna, Fjällräven, and Haglöfs.
