Nimbus
$44.99 $49.99
For wet-weather and winter riding, Nimbus are waterproof and breathable over-the-knee bike shorts to keep you dry and altogether more comfortable.
- Reliable and hardwearing 3-layer waterproof fabric
- Reinforced double-layer seat for extra durability
- Over-knee fit to prevent knee pad gaps
Nimbus uses a 3-layer performance fabric that is highly waterproof (20,000 hydrostatic head) and highly breathable (20,000 MVTR) and is treated with an environmentally friendly PFC-free water repellent.
As well as the hardwearing 3-layer fabric, the seat and inside leg are reinforced with a double layer of material, providing protection from abrasive grit and another extra layer of waterproofing. If you need to let off some steam mid-ride, the zipped pockets are mesh lined to double up as vents.
The Nimbus sits higher at the rear to keep your back warm and protected from spray. And a double press-stud closure and elasticated Velcro adjusters ensure they don’t slip down while you ride.
