More breathable and even faster-drying: this evolved version of the Winter P1 balaclava combines thermoregulating properties with rapid sweat expulsion to keep skin warm and dry-especially important when temperatures drop. The insulating layer provides a level of thermoregulation suitable for the cold of winter (except when the weather gets extreme) while the soft, highly elastic fabric is pre-shaped to wrap around the head, face and neck without squeezing.
