The PEARL iZUMi AmFIB Bib Tight is designed for riders who refuse to let cold, wet weather end their season. Built as a full-length thermal bib tight, it combines insulating fabrics with wind- and water-resistant panels in key areas to keep your muscles warm and protected on long winter rides. The close, anatomical fit supports efficient pedaling, while stretchy materials allow a full range of motion whether you are grinding up climbs or cruising on the flats.
These bib tights typically feature a soft, brushed interior that traps warmth and wicks moisture away from your skin, helping you stay dry even when you’re working hard. Flatlock seams and carefully placed panels reduce chafing and bulk under your jacket and over-shorts. The upper bib section holds everything securely in place without digging into your shoulders, so you can focus on the road, not on adjusting your clothing. Reflective details are often included to enhance visibility in low-light conditions, making the AmFIB Bib Tight a smart choice for early morning commutes, evening training rides, and all-day winter adventures.
