There is nothing more embarrassing than arriving to work, to a meeting or worse of all to a social occasion with a wet bottom. It is uncomfortable not to mention highly unsightly! Waterproof wear is well worth investing in.
Opting for the cheapest items on the market can often end in quite a lot of discomfort. Waterproof fabrics need to be breathable otherwise they can have a ‘boil in the bag’ effect which let’s face it is not very pleasant.
To keep your bottom-half dry there are a couple of options available. You can either opt for a waterproof pant, which I am afraid are often not the most attractive items on the planet, or, alternatively opt for a rainwrap. The latter is particularly good for city riding as it can be easily slipped on and off and is even skirt friendly!
