Waterproof
A female-specific waterproof cycling jacket is your best friend. There's nothing more joyous than looking a downpour square in the eye and pedalling on. Get the right one, and no conditions can keep you off your bike.
Take your pick from subtle sophistication or unmissable high vis, lightweight and packable for road adventures or warmer and more substantial for commuting or mountain biking. Then get out and defy the elements!
