The Columbia Iceventure II Bib keeps us protected from winter's worst while we breeze down groomers at the resort. The waterproof, breathable Omni-TECH laminate keeps wet snow from drenching our baselayers and efficiently dissipates heat to keep us cool and comfortable on the hill. The Omni-HEAT thermal reflective liner sends our body heat back toward us, offering an extra layer of warmth for cool, crisp days in the mountains.
