The Assos Spring Fall Neck Warmer P1 handles that tricky temperature range where you need coverage but can't afford to overheat. Assos redesigned this version with a more anatomical fit that wraps around your face, chin, and throat without the awkward bunching or pressure points that make some neck warmers feel like they're strangling you mid-climb.
The real improvement here is breathability. When you're pushing hard in cool conditions, moisture buildup under a neck warmer turns uncomfortable fast. Assos increased airflow specifically over the mouth and nose, so humid breath escapes rather than condensing into a clammy mess against your skin. The polypropylene-dominant fabric blend wicks efficiently while the elastane content keeps everything in place without relying on excessive compression.
Circular seamless construction means no seams rubbing against your neck or catching on jersey collars. The pre-shaped design sits naturally without constant readjustment, whether you're tucked in the drops or sitting upright. It layers cleanly under helmets and works equally well pulled up over your nose or worn lower around the throat when conditions warm up.
