Insulation sits only where a snowboarder or skier loses heat first on the Volcom Creston 3D Stretch Bib Pant, with 60 gram low loft stretch insulation on the thighs and seat. These insulated ski and snowboard bib pants wrap that warmth in a stretch recycled shell and a stretch lining, so the rest of the bib stays free of bulk. What Our Gearhead(R) Experts Are Saying:"When a long insulated day starts to run hot, the mesh-lined zippered vents are the first thing I open to let some heat out."
