I have the merino base layers including the briefs, the switchback pants, the element pants, the midweight zip top, and the torrent rain jacket.
I found all of the pants and tops to be a perfect fit for me, and the merino didn't have any noticable itch for me. I am 5'-10", 190#, 35"-36" waste.
I have only had the jacket for a short time, and have only gotten out in the weather once. I am not quite dialed in on how to cinch up the jacket. I like it to zip up and stay in front of my chin. I found that I didn't have alot room to move without my chin wanting to come out of the "nest". My old jacket seems to give me a little better range of motion without causing problems, but it is like a sweat bag.
I would not hesitate to buy more of their gear.
