"The Crater IV is our most versatile GORE-TEX hardshell for mountain activities. Whether it's day hikes, multi-day trekking, or mountaineering in harsher terrain, the Crater IV perfectly balances a breathable lightweight construction alongside durable weather protection.
With the introduction of the new ePE membrane technology by GORE-TEX, we were also able to make an important step towards a more responsible future, by eliminating PFCs and ultimately reducing the overall carbon footprint of the material."
