The best part about this jacket is the fact that is has some nice storage pockets, even though they are lined with a plastic liner. It nice to have the pockets, as is so easily accessible when you are out riding. You don’t have to remove the jacket to grab something out of it, while wearing it.

4. Granger's Clothing Wash + Repel

Our rating: 8 / 10

Granger's Clothing Wash + Repel

Check Price on Amazon


  • Washable in your home washing machine
  • Best for waterproofing your current outerwear
  • Smells great and clears bad odors
  • Not for all outerwear types


  • Waterproof coat must have been manufactured in the UK or US
  • Not for silnylon or other waterproof coated clothes

If traditional waterproofing products are just too messy for you, then this is the safest way to waterproof your outerwear.

This is ingenious stuff from Granger's Clothing that you can wash right in your home washing machine. The Wash and Repel For Outerwear is for jackets made from cotton or cotton blend cloth/membrane products. The waterproof coating helps to repel water from the exterior of the fabric.

In other words, this product helps to repel water, rather than keep water out. This increases breathability compared to a garment treated with a DWR coating, which is much less breathable.

Frequently Asked Questions (FAQ)

What is the best waterproof cycling jacket?

Any time you are shopping for a cycling jacket, you’ll find yourself separated into two camps, the outer shell and the rain jacket. It can be best to view them as two completely different pieces of clothing because many jackets combine both elements together.

Rain jackets were originally considered as separate garments, typically made of waterproof fabric, which was breathable, and had functional pockets and adjusters.

The outer shells tended to be compact shells that didn’t offer as much protection.

Most cyclists two decades ago would consider rain jackets as a sort of secondary layer that was added on top of your jacket. Today, the lines are less distinct and many cyclists will combine the two together to get the functionality of both.

They still work perfectly well as separate garments but, by combining the two, you can enjoy all the benefits of each without the downsides.

What is the best rain gear for cycling?

Understanding the different styles of rain gear for the bike will help you select the right one for you. Styles include:

What is the best waterproof hunting jacket?

What do pro cyclists wear in the rain?

The thing about pro cyclists is that they want to feel like they can do everything and they want to do everything, so they like to use all of the equipment that any rider might use and they look for items that will help them to do that, but they also want to do it at the highest level possible which means they want the lightest equipment. So, their choices always need to be considered within that context.

Pro cyclists do not want to carry around extra weight, they want to be able to pack light. Portable forms of equipment are what pro cyclists seek after.

Pro cyclists are like the average cyclists in that they also want the best performing rain jackets available at the moment, but they are more concerned with the aerodynamics than most people. They don’t want their rain gear to add to their already significant air resistance.


When you get caught in the rain while cycling, your clothing and gear should keep you comfortable. This is why you should have the best waterproof cycling rain jacket you can find. We’ve researched tons of options in order to come up with our list of the 5 best waterproof cycling rain jackets in 2021.
