Put simply, the Berghaus Men's Vapourlight Hypertherm Jacket is the lightest and most versatile synthetic midlayer currently available. Anywhere.
This reversible jacket is ideal for active users out in the mountains. It is effectively two jackets, offering different degrees of warmth so you can tailor your insulation to the needs of the moment.
By using two different outer fabrics, Berghaus have created a jacket that has different ways of controlling the way air passes through it. One side is best used in colder conditions, with a highly wind resistent outer, it prevents cold winds from entering and traps body heat inside. When worn in reverse, there is an air permeable outer which reduces the amount of body heat trapped by allowing it to escape and keeping you cooler.
