Waterproof trousers are one thing I'm having problems getting right. In general I destroy a pair in 2 weeks. Here's my personal view, it's worth what you paid for it:
Paramo - black and a bit noisy but not too bad. Lasted no time at all and not waterproof if you sit/crawl in them. Comfortable with zips down inside leg for ventilation. Great for walking to trout fishing, no good for stalking.
Deerhunter - Didn't last long and were not very waterproof but were quiet and reasonable camo pattern. Don't think I'd have another pair but maybe good for light use.
Cabelas - Various versions of their own brand camo waterproof trousers. Excellent job, some are a bit too warm for all but winter or highseat stalking. Seem to wear well and comfortable. Reasonable prices. My current pair is too warm for all year use but they get a lot of use in winter and were not expensive. Worth a try if you are in the US or if you fancy the risk/cost of getting some posted to you. Cabelas seem to have good service etc.
Harkila - Got a pair of very lightweight Harkila Grizzly Brush trousers. Camo pattern a bit odd but doesn't work too badly on the hill. Didn't think they would last a week but they have and I'm still wearing them 4 months later. Swillington have them for £99 and worth it if you ask me. Sensible pockets, very waterproof. Not too warm. Comfortable. Have looked at the other, heavyweight, Harkila stuff and very good quality and most of it looks like it would survive but suspect it might be a bit hot for all but winter stalking on the hill but might do all year round in forest/high seat type stalking.
