I use them for commuting, 2.5 hours per day and found them very comfortable, warm in the winter and have never got wet while wearing them, I don't know what happened to the other reviewers but I have been in many downpours without any problem.

I am a very tall rider, 6 ft 7 in (200cm) so the leg length on the Richa Monsoon Trousers was a very important factor for me. This was pretty much the only thing I could find with a long leg so I didn't have much of a choice to give it a try.
I use my bike to commute to work in the city of London and I wear a suit to work. Thus I was looking for something to wear over the suit. I am more than 100% satisfied with the product. The legs are indeed very long (even longer than I actually need them to be but you can adjust the length so it is perfect) and the protectors are in the right place when you sit on a bike, something that is usually a problem if you are a tall rider. It is relatively easy to put them on and to get them off once you reached the office. Walking in them is no problem either. They are perfectly water proof and keep you warm and don't heat up too much in the summer.
They do not come very cheap at 99 quid but then again you should not try to save on your gear. They are money well spent. I can only recommend this product, especially the long leg version to every tall rider looking for something like this.
