I have a Joe Rocket meteor suit. The waterproofing is in the jacket, not the liner, so it's waterproof summer and winter (watch that, a few of the Jackets have the waterproofing in the liners for some odd reason??).

Pants zip apart right up to almost the waist, making it really easy to get into in a hurry with boots still on!(the side Zippers on the pants Zip both from the top and from the bottom so you can access pockets in whatever you are wearing underneath without having to go in either through the waist band, or unzip from the bottom.)
Pants have braces-Yeah a bit of a grandpa look, but it makes it loads more comfy as you can have them loose around your waist and they still stay up!
Both the liners are toasty warm.
Both are really dry! (some small leakage around the gap in between the pants and jacket over a long period in the rain but doesn't compromise warmth.
Loads of Air vents for warmer riding, and can be used as a Psuedo climate control by opening and closing the zips. A neat feature in the less arctic climates.
Tough- I have crash tested these. They burst open on the impact point on the elbow, but didn't damage anything underneath. So I was able to sow the outer shell back together. the pants have a grind mark but that's it. Still in service and working as intended.
They were pretty cheap too when I bought them. About $300 for the jkt and $200 for the pants or sumfink close to that.

All those Zippered air vents work mint in summer, but the arm zips cause leakage of cold air on really really really cold days. Which means a thermal top in really cold conditions is required under the Jacket. (Just as a reference point, do keep in mind that I really really really feel the cold

I am a skinny little fecker with no fat to insulate me, so when I say a thermal, most normal people would prolly have a T!

)
The gap at the front, between jacket and pants will let a little water in over a long day in the rain.
The pants can get hot on a warm day. Even with the liner out! Although, of late I have taken to undoing the top part of the side Zip to control air flow which seems to work.
