We built the Cardiac Gore - Tex 3L Bib Pant to be the cream of the crop in our outerwear line. These pants pair a Pfas - free Gore - Tex ePE laminate with fully sealed seams and an underbust bib to keep the weather and sweat out of our layers so they can do their thing. With this waterproof and breathable coverage, we can spend more time on hill where the 2 - way side zips, multiple pockets, and self - adhering bib straps promise further comfort as we get the goods.
