Waterproofing layers like the Frontier Pants are essential in providing protection when the weather turns. The Frontier Pants provide shelter in unexpected storms and downpours while the membrane actively removes water vapor through small pours, making the jacket work for you. This allows you to remain active and focused. The Frontier material is a durable construction, providing protection in bushland and resisting punctures in the field. Heavy duty, packable, and extremely waterproof – perfect for Winter months. Frontier Pants are the necessary protection on a rainy adventure. If the jacket is doing its job too well and you start to run a bit hot, partially unzip the side zips to dump heat and keep going. Ideal for thick of winter expeditions and a perfect protection layer in your winter layering system.
