AmFIB is PEARL iZUMi's cold and wet-weather fabric system, engineered to block wind, resist water, and hold warmth on the harshest winter rides. You'll find it across jackets, tights, gloves, and shoe and toe covers.

AmFIB fabrics are highly wind-blocking and water-resistant with thermal insulation, built to shrug off cold rain and spray. For sustained downpours, pair AmFIB pieces with a seam-sealed shell from Wet Weather .

What products use AmFIB?

The collection spans insulated jackets, bib tights, full-finger and lobster gloves, and toe and shoe covers and accessories , everything you need to seal out deep-winter cold.

What temperatures is AmFIB designed for?

AmFIB is built for cold to frigid conditions, roughly the coldest end of the range where you'd otherwise cut rides short. For milder cold, lighter insulation may be all you need.

How do I care for AmFIB gear?

Close the zips and fasteners, wash cold, and skip fabric softener. Reproof the DWR finish periodically so water keeps beading off the surface.
