Look no further than the Marmot Spire bibs when it's dumping and you've got to lace some lines through the trees. The Spire bibs feature 3-layer GORE-TEX to keep you dry during the deepest days, while elasticized gaiters and water-resistant zippers seal out the elements when you take a tumble. The Spires' adjustable suspender straps are removable, so you wear them as pants during clear spring days. Plus, a full-length side zip makes for easy on and off when you're in a hurry to get into your après-ski clothes. 3-layer GORE-TEX and fully taped seams deliver weatherproof protection Pockets with water-resistant zippers for secure storage Articulated knees for improved mobility while skiing Removable suspender straps for versatility as a pant or bib Equipped With GORE-TEX GORE-TEX is an extremely thin membrane that’s durably waterproof, windproof, and breathable. It has over 9 billion pores per square inch that are each 20,000 times smaller than a water drop, but 700 times larger than water vapor. This means that rain won’t get through the membrane, but that perspiration vapor can escape. Different iterations of this basic membrane principle are in a variety of products throughout the outdoor industry. Durable Water Repellent (DWR) DWR is a fabric treatment that improves the water-repellency of the outer layer of the material, while maintaining its breathability.
