Built for deep snow and steep lines, the award-winning Environ Bib is our fully featured waterproof ski bib that provides premium weather protection on either side of the gate. Our seam-sealed, 3L PeakProof⢠DermizaxÂŽ waterproof shell fabric is super durable for day-in, day-out use, and the Environâs high-waist and suspenders provide optimal performance when hiking and ample coverage in the blower conditions you dream about. Side zip vents with YKKÂŽ water-resistant zippers let you ditch excess heat and also double as a drop seat. Articulated knees and a gusseted inseam improve freedom of movement on skin tracks and cliff drops, and zip hand pockets and a zip thigh pocket stash your pass, phone and other on-mountain essentials.
