The ideal mid-layer for climbing and mountaineering expeditions, our Bolt Polartec® Hooded Jacket gives you the protection you need to power through cold conditions. The Polartec® Power Grid™ fleece fabric packs impressive warmth for its fabric mass. It won't weigh you down or cause you to overheat. In fact, you'll hardly even notice you're wearing it. The geometric pattern optimises wicking and breathability so you can move through the mountains without overheating or getting wet from the inside. It's incredibly compressible and fast-drying, too, allowing you to regulate your body temperature when wearing a heavy pack or waterproof outer jacket.
