Ride like the wind. Not against it.

CFM is a key indicator of how well air moves through equipment or around the cyclist’s body. Whether it’s for helmets, fans, or clothing, a higher CFM generally means better cooling — a significant performance and comfort factor for any cyclist.

For sub-freezing rides, look for gear that combines maximum insulation with full wind and water protection. Our AmFIB® softshell technology is the ideal choice—it’s our warmest outer layer, offering zero-CFM windproofing, excellent water resistance, and a cozy fleece interior for insulation. Pair AmFIB® outerwear with a thermal base layer and, if needed, a mid-layer like a fleece or lightweight insulated jacket to create a system that traps warmth while managing moisture. This layered approach ensures comfort, mobility, and protection even in the coldest conditions.

WindPro and Pearl iZUMi’s Barrier fabric both offer excellent wind protection, but with different strengths. Polartec WindPro is a high-performance, breathable fleece that blocks up to 85% of wind while allowing heat and moisture to escape, making it a great choice for active rides in cool, dry conditions. Pearl iZUMi’s Barrier fabric delivers complete windproof protection (0 CFM) and impressive water resistance, offering reliable comfort and coverage in wet, windy, or variable weather. Both fabrics are thoughtfully engineered to enhance performance and keep cyclists comfortable across a range of conditions.

Absolutely! Pearl iZUMi’s windproof gear, including our Barrier fabric pieces, is designed to layer seamlessly with other apparel. Pairing a windproof outer layer with moisture-wicking base layers or insulating mid-layers allows you to adapt to changing conditions while staying warm, dry, and comfortable. This layering system helps regulate body temperature and maximizes performance whether you're riding in cool breezes or braving harsh winds.

Start by considering the typical weather and your activity level. For cool, dry, and high-output conditions, lightweight and breathable options like our PRO or Attack Barrier jackets and vests offer excellent wind protection without overheating. In wet, cold, or variable climates, choose gear with enhanced water resistance and full windproof coverage, such as pieces featuring our AmFIB® softshell or Barrier fabric, to stay warm and dry. Layering with base and mid-layers gives you flexibility to adjust as conditions change.
