There's nothing quite like the stomach tightening feeling of seeing menacing clouds descend over the cliff wall you're clipped onto, but luckily the Columbia Women's Evapouration Trench Jacket is prepared to keep you dry as you climb down for shelter. With a waterproof Omni Tech shell and fully taped seams, this jacket naturally sheds water so you stay bone dry as you head back to camp. If the winds pick up, you're able to hunker down by adjusting the Evapouration's hood and cuffs while still being able to carry a backpack comfortably. When the clouds clear and the heat picks up, the jacket's Omni Wick EVAP finish helps evaporate your sweat into the air while the two way underarm zip vents dump excess body heat. The Evapouration also stows into its own hand pocket so you're able to store it in your backpack during day long expeditions.
