The warm, protective design is great, but it's really nice knowing that this bib's construction is reducing our impact on the planet. -Gearhead(R) Expert JoCold days on the mountain call for fully featured insulated bib pants like the Backcountry CrestCruiser Insulated Bib. We designed the CrestCruiser to bring us total performance and comfort on the mountain at a competitive price. The CrestCruiser Insulated Bib features a waterproof and breathable polyester fabric that is topped off with a PFAS-free* laminate and DWR treatment and fully sealed seams. We packed 40 grams of insulation in the bib and 60 grams in the pants to ensure we stay warm and comfortable in chilly conditions. Mesh-lined zippered vents on the thighs allow our body to breathe when we are getting too hot, and ankle gaiters combined with a drawcord cinch at the hem ensure the snow stays out.*made without intentionally added per- and polyfluorinated substances; may contain trace amounts
