The Climate base layer is an undergarment in pure Merino wool. It is ideally suited to the cold, but also to hunts where activity levels are constantly changing. The Climate base layer is made from pure Merino wool, which has superb insulating and heat-regulating properties. The wool fibres can absorb moisture and still keep their shape. So the wool warms you, even when damp, and you do not feel cold and clammy, when you switch from high exertion to walking or sitting. The Climate baselayer has flat seams, so you stay comfortable. Its active design ensures a good fit and it stays in place, however much you move. The Climate base layer is the ideal inner layer for all kinds of hunting activity. 100% Wool - merino.
