I bought a pair of their pants first, mainly cause of a deal (surprisingly not SAC/TD, B&M actually), but I liked them from what I could tell in the store. Then later got a jacket on SAC, again cause it was a deal. I'm pretty sure both are Ridge series, 10k waterproofing.
Overall pretty impressed with both. Stuff seems pretty bomber, bottom of the pants are starting to get a hair chewed up, but nothing worse than what I have done to every other pair of pants I've owned. Thats what Duct tape is for. Interesting thing on the pants, vents are on the inside. At first I wasn't too sure about this, but its kinda nice on a spring day, far better ventilation than size zips. Really keeps the boys comfy. The fleeceish lining on the pants is nice too as I rarely where more than a pair of mesh shorts under my ski pants. My favorite feature on the pants is by far the pass holder in the pants, I always wear the same pants, I don't always wear the same jacket. No more forgotten passes.
The jacket is great, with only a few minor flaws. I wish the powder skirt was a bit more adjustable, I need to really crank the elastic down to get it tight and the "watch window" is a pretty dumb idea that just tends to collect sweat.
Waterproofness has been more than sufficient for me and I have skied in the rain wearing this gear.
For the price it can be found for on Sacdock, I highly recommend Sessions gear, or at least the stuff I've tried.
