As we start our hike, the wind is really blowing. We put on our 3-layer GORE-TEX ePE jacket. Its new waterproofing membrane has never been more effective against the elements, and it also reduces its environmental footprint. We adjust the hood, tighten the hem, and cinch the cuffs using the hook and loop fasteners. With its active cut and raglan sleeves, we have plenty of freedom of movement. Harness compatible, we can pull our gloves out of the top two zipped pockets. As we climb harder, we open the underarm vents to regulate heat.
