The GripGrab Merino Blend Half Zip Thermal Long Sleeve Base Layer is the height of luxury winter layering. The unique two-layer fabric combines a merino wool outer with a viscose inner, to create a super soft, incredibly breathable and highly insulating base layer.

The two natural fabrics are known for their outstanding temperature regulation and wicking performance, so they will keep you comfortable even when you are working hard in the winter months.

The turtle neck collar provides extra warmth and protection, but when you do need to 'vent out' the half length zip makes it easy to encourage airflow through the layers.

Thumb holes are great for keeping the base layer in place when putting on your other layers.
