Extreme Warmth

The Montane Anti-Freeze XT is warmer than the original Anti-Freeze to perform in higher altitudes and wintry climates. Whether you’re belaying at the ice crag or conducting an ECT on the tour, the Anti-Freeze XT’s 700-fill down insulation warms you when you need it and packs away when you don’t. Montane treated the down with HyperDry to retain its lofty warmth in wet weather. The Pertex Quantum Eco shell is water-resistant and windproof for extra weather protection, and its fabric is 100% recycled for an environmentally thoughtful design.
