To keep our bones from chattering on winter treks, we zip into the Infinity Summit. The Double Wall construction gives us windproof protection on blustery ridgelines, and with its Lolefty down and heat-reflecting liner, we get two levels of defense against icy temps. When it's time for that neverending push up the last steep, this jacket packs down into its own chest pocket for compact stashing as we build our own heat.
