Top 3 favorite in baselayers
I have several different base layers, and this one is in my top 3 favorite. I love the Patagonia capilene line. Each is different and has it's own unique feel and features. The capilene 3 is designed for cooler weather. To me it has a different feel than the cap 1 and 2. But like the other 2 it is very comfortable. Its light insulation kept me warm in temperatures ranges from 40 to 60 degrees. If it's much warmer than that I'd use the cap 1 or 2. If it's colder than that I'd use the cap4.
I like the fit, but the 2010 and 2011 versions have a little different than the 2009 version, in that is a little looser, which I personally like. Around the arms and wrists it fits ever so slightly loose. But not so much that it would seem baggy or not insulate.
The cap 3 is 100 percent polyester, meaning it is obviously made of synthetic material. When I compare it to merino wool, I think it is just as comfortable but it is much more durable, and is much less expensive. So I tend to buy more synthetic base layer as opposed to natural base layers.
I really like the 2011 colors. Once they go on sale or if this review get approved, I might buy some more
