Say goodbye to messy hair! Unlike most wrap-around earmuffs, these don't. Our sleek design provides warmth without sacrificing style. For those with long hair, the earmuffs can be discreetly tucked behind the hair, making them virtually invisible. Patented Snap-On Technology - The earmuffs are made with patented snap-on technology. Each package contains an earmuff that snaps onto each ear. This compact design makes them easy to store and carry. Most customers order multiple pairs and keep a set in each jacket for easy access. Watch the video to learn how to wear the earmuffs. Lightweight Performance - The earmuffs' lightweight design makes them the perfect accessory for cold-weather outdoor activities. Popular activities for customers using earmuffs include, but are not limited to, running, skiing, cycling, ice skating, snowboarding, and more.
