The zippered clamshell version of Black Diamond's tried-and-true on-route Speed pack, proven everywhere from the Canadian Rockies to the Fitz Roy massif, the Black Diamond Speed Zip is designed for lightweight performance on rock, snow and ice objectives the world over. Featuring an updated BD X-rip 210d fabric with UTS coating, the Speed Zip is built to withstand season after season of mountain abuse. Weve improved the comfort as well with a moisture-wicking, updated back-panel and redesigned shoulder straps of dual-density foam for better load distribution on the approach while remaining streamlined on route. Ice tool PickPockets now feature a custom metal dogbone ice tool attachment, boosting ice tool security, plus the snag-free crampon straps and a tuck-away rope strap secure gear to the outside.
