I'm 5'6" and went for the large Jacket and large pants. They both fit big and the jacket nice and tall. If you are my size you could definitely go for the XL in the Jacket, not the pants though. The pants sit really low thanks to the brace/bib style and are very comfortable indeed. The crotch sits i bit below my knees, any lower and it would limit my movement. Anyway L for me fits nice and big, not over the top but just right.
Both the Jacket and pants are suprisingly warm. The jacket seems thin to me cos I'm used too a big Candide puffer jacket but i still feel very insulated. The pants bib make you feel like your in a one piece. I'm really happy with how it is in this area.
The jacket is definitely not as waterproof as my good old Candide jacket. It does soak up water rather than repel it, however, for the money i payed I'm not disappointed by any means. The jacket is in a different price range from super waterproof North Face or any other extremely technical outerwear.
The Jacket has lots of external pockets, including the big kangaroo one that goes across the zip. This pocket is easy to get to and I think looks cool. There are no zip up pockets on the inside, no velcro ones either, there are meshy slit things that aren't too useful. The pants pockets are just like any other a bit awkward to get to sometimes.
I have had no problem with stitching, the colours look great. I will update this thread if i have any problems.
