The Y-1 EPE is a serious shell pant for skiers who spend long days outside and want dependable protection without unnecessary bulk. Built with a 3-layer GORE-TEX ePE membrane rated 30,000/30,000, it is fully waterproof, windproof, and highly breathable, with a rugged 150-denier face fabric made to handle hard use in the mountains.
The cut is built to move, with articulated knees and a crotch gusset that keep the pant comfortable when you are skiing, hiking, or working through technical terrain. Large side vents make it easy to dump heat when the pace picks up, while a soft flannel backer adds comfort against your layers. A small Sorona-insulated insert at the back of the waistband is a smart detail that adds warmth where cold air tends to find its way in.
Cordura 600D scuff guards protect the lower legs from ski edges and boots, while fully taped seams, waterproof zippers, adjustable waist tabs, and integrated snow gaiters round out a shell designed for real winter use. The ePE membrane and DWR treatment are produced without added PFAS, and Mountain Studio includes a repair kit to help keep the pants in service longer.
This is the pant for days when the weather is doing exactly what you came to the mountains for.
