No regrets
The only complaint I have is that I wish this top were several inches longer. I have a long torso and while this top is longer than Patagonia's offerings, I wish it were just a few inches longer. Regardless, this top is warm, very stretchy, not itchy, and perfect for the backpacker, hiker, or climber. I purchased this top for extended backpacking trips and climbing. While I have yet to take it out on the trail for days, I have worn it climbing and it has performed wonderfully. I have washed it-- in cold water with Tech Wash, and have not had any problems with shrinking. However, I did first order an extra-small, as I wear an extra-small in everything, and had to exchange for a small. It fits like a glove even then, so if you want something with more room for multiple base layers, order a size or two larger. I could have gone with a medium and been fine. This top is definitely worth the investment!!

good shirt.
I have owned men's rho lt zip. It is warm, soft and comfortable. Gave a gift to my wife. My wife said, "really the best shirt '

Just what I wanted
I love the fact that this warm layer fits snugly, but is very stretchy and comfortable to wear as well as to put on and take off.

Awesome base layer!
Wow! This top is wonderful. I bought one last year and loved it so much that wore it alot running errands, on various outdoor activities. It handled the body movement very well. It is very stylish and doesn't look like a cheap baselayer. You gotta get it tight to your body for maximum moisture wicking benefit.

worth every penny
I love this piece because it does the job. Close fitting. Warm as toast. Washes well (follow instructions) I loved the black one so much I got brown one too. Fantastic base layer!
