I can recommend the suit I use, an Ozee Millennium
http://www.ozee.co.uk/shop#ecwid:catego ... ct=1727111
It's mostly sold to microlight pilots but it has been excellent for paramotoring. It is waterproof (so never an issue setting up in a wet field), windproof, incredibly warm and tough but very easy to move about in. It has a large clear pocket on the leg, loads of other pockets all over. easy access zips for legs, etc. It's also very tough. Mine was made to measure for no extra charge (you can choose your colour, I had all black). The pics on their website look a bit naff bit they are very good suits.
I went up today with just a light fleece on underneath, it was minus 3 on the ground and I was as warm as toast in it for about an hour.
