Icebreaker Pure Merino Wool Base Layers

The alpine merino wool in your icebreaker thermals is much finer than traditional wool. Being so fine, Icebreaker merino wool is silky soft to touch, insulates much better, breathes far more effectively which keeps you fresh and dry and doesn't hold odour so you can wear it for more days unlike many synthetic layers.
Icebreaker is a system of pure merino layers where each layer can be worn solo, or with insulation layers to combat the extremes. The layers work with each other to provide warmth when you need it. By layering your Icebreaker you dramatically increase the thermal potential of the system (more fibre = more insulation) but because the system breathes so well, you don't overheat
