The matching lower half to our Belay Parka, the Belay Pants are super-warm, insulated puffy pants for teeth-chattering, feet-stomping belay conditions.Designed to be worn over shell pants and featuring two-way insulation filled with 60 gsm of Primaloft Gold Crosscore insulation and 40 gsm of Primaloft Rise insulation, they insulate even when wet, thanks to a 50D ripstop shell with DWR plus a 20D nylon taffeta liner. These versatile belay pants compress in your pack and feature full-length side zippers for easy on and off while wearing crampons. An integrated adjustable belt helps you dial in the fit over varying layers.
