Summer hiking and trekking involves unpredictable mountain weather. The Zeta SL Pant is designed specifically as an emergency shell for hiking. It packs up small so it's ready whenever sudden storms arise. This superlight, packable, emergency waterproof pant is made from GORE-TEX fabric with Paclite Plus product technology. The minimalist design and fully articulated patterning gives an exceptional fit and freedom of movement. A zippered fly with a snap closure has an internal webbing adjuster for a secure fit over a layer. The 3/4 length WaterTight lower leg zippers ease on/off with boots.
