The modern form-fitting lines paired with the stretchy polyester shell make the Summit Snow Pants of the White Wave Collection a breathable insulation layer for warmer days on the mountain. Although ultra-lightweight, the 15K ROXY DryFlight technology of these shell snow bib pants guarantees high-level waterproofing. We made comfort a priority, so the elastic suspenders are adjustable, while the bottom leg gusset zips up, so you determine what works best with your boots.
