Reflective Safety:Golden reflective logos enhance visibility during night rides and the warning effect. Practical Storage: Three rear pockets for easy storage of personal items. Thoughtful Design Non-Slip Construction: A 4.5 cm wide, printed-on non-slip strip at the rear hem prevents the jersey from riding up and keeps it stable while cycling. Collar Detail: V-neck reduces pressure on the neck. Combined with the smooth YKK zipper for easy on/off and an overall aesthetic appearance. Lightweight Compression: The entire jersey weighs only about 135 g (size M), is lightweight and breathable, yet provides compression and support.
