The PEARL iZUMi AmFIB Bib Tight is our secret weapon for fighting the winter doldrums. Made from PEARL iZUMi's water-resistant AmFIB softshell material and a recycled fleece lining, these bib tights are built without a chamois so that we can wear our choice of chamois underneath. PI Dry technology helps shed light moisture while the raw cut bib straps reduce bulk for comfortable layering no matter how much the mercury drops.
