I heard this Capilene things for a long time, many of my friends recommend this to me and I finally got one.I must say patagonia really made good stuffs, this C3 is breathable and wicks well. Adds just enough extra warmth to regulate your temp on a chilly day.Also its lightweight, dries fast, great for all outdoor activities, or just hanging out at home. Love it and will buy more in futrue.
This midweight baselayer is great for fall, winter and spring. Breathes quite well and insulates pretty good without it being tight as a two-dollar watch. The sizing is a big large though. I am 6'1" 185lbs with a 41" Chest and 33-34" arm length and a large hangs off of me a tad bit. I have room to wear a t-shirt under it, even though I was looking for a next-to-skin fit. If you are looking for a trimmer fit as well, go a size down. There was alot of shirt leftover to tuck in. All in all, a great looking and wearing midweight.
Don't leave home without it! I use this as my go-to baselayer and wouldn't think of using anything else. I typically don't have to wear a midlayer when skiing with temps north of 20F (I'll just use this guy along with my Patagonia Primo Jacket). Sizing does run a bit large though. I'm 6', 175lbs., and have a fairly athletic build and a large is...well...larger than what I would've liked.
Very nice base layer! Not very thick but definitely holds a good amount of warmth in. I bought this in a medium and an Arc'tryx mid-layer in a medium at the same time. This runs just slightly longer in the arms and length than the Arc'teryx. I'm 6'0, 150 pounds and it fits great. Haven't noticed any stinking issues.
Pro's-Athletic Fit (I'm 5'7 140lbs and the Small fit me just fine...actually I look kinda muscly in it)-Wicks away moisture like no other-Stylish. I have no problem wearing this for a night at the bar-Durable. Con's-None yet, this thing is awesome. This is my first Patagonia crew and it will not be my last, I plan on buying many more. These shirts are awesome!
If you want a base layer that will keep you warm (that's why it's a level 3 Capilene), dry (Capilene), long sleeved, avid outdoorsman shirt then buy this shirt. I've purchased several x3 over the years and am never disappointed. Patagonia tends to run a little large for some reason (or at least every product I've ever purchased from them) which means my 6', 180 lbs frame wears a medium. Definitely do not buy the large unless you were looking for a dress, in which case do buy a large...because it's a dress.
