The Fly LS Jersey is a lightweight thermal long-sleeve jersey for those days when it's just a bit chilly and you're looking to go fast. The soft brushed-back Fly T-SL fabric offers the right amount of warmth while being stretchy and lightweight. We've tailored the Fly LS Jersey for a close-to-body fit.

Fully waterproof jacket for when you need complete protection, whether from rain or just from cold. Styled so you can wear it off the bike too.

The thermal jersey for the cyclist who prefers a jersey and vest in cool conditions instead of a light jacket. The brushed fleece fabric keeps you warm but also has enough stretch to ensure a perfect and comfortable fit.

This lightweight head thingy is the perfect weight to keep the chill out on those early fall rides or to provide a little added protection from the sun's rays.

Made from 100% post-consumer polyester from recycled plastic bottles, this sock provides a nice amount of warmth without adding bulk. A great sock for the fall or early spring.

The Fly LS W Jersey is a lightweight thermal long-sleeve jersey for those days when it's just a bit chilly.
