The fit is perfect and it wicks moisture fast. Very obvious comfort over a huge range of temps.

Good fit and the fabric feels good. Love the neck thickness and height, also, so far it doesn't have the capilene funk.

This is one piece that will always be in my arsenal. Whether it be summer alpine climbing or winter backcountry skiing, I always have this piece. I'll throw a Capilene 2 underneath and a softshell over, and I'm set for a day of romping in the cool to cold.
It's got a great fit that isn't too tight, nor is it very loose. It's easy to fit one layer underneath, but not much more than that otherwise the fit would start to be tight.

I am 6'4" 190lbs. I usually wear a large or XL. I ordered a large and to my surprise found it to be quite loose fitting and baggy. Considering that this is a performance base layer I would have expected it to be a closer fit. I do not see how it can "wick moisture fast" if it does not even come into contact with the sweat. There is no elasticity to this product. I do not recommend it as a performance base layer. It may work as a regular clothing item if you like wearing polyester.

Patagonia is the best....and this Cap 3 Zip Neck will be all I need for my baselayer. The shirt is totally true to size and fits great. Not only will I be wearing it as my baselayer, but can be used as a regular shirt to wear around town......Looks great, feels great.

The 3 is the ideal weight. and the zip makes it comfortably adjustable for anything but the hottest or coldest weather. My comfort range in it is probably ~75 down to ~45. It fits well, (slim but not snug), holds off the stink long enough, dries fast enough and looks nice enough so you don't have to change immediately after wearing. Made well-enough that you'll only need one for a long time.

this top is really worth every dime, and i got it discounted on backcountry with great service as always. The capilene 3 works great in cold temps as a stand alone baselayer (i wore it alone while doing some winter backcountry camping in rocky mountain np and it kept me warm and comfortable). i am 5'9 220 and the XL works perfectly. get one! or two

Fits well and keeps me warm. I wasn't sure that it was worth the money, but it definitely is.

These are super warm, breath well, and are nice and light. The zipper is critical if you're engaged in any activity. I'll wear it around camp, but only during activity if temps are freezing. Highly recommended.

This shirt is great. i wear this skiing and I stay warm and dry no matter how cold it is or how much I sweat. I also were this on cold bike rides. love it so much I bought 3 more.

This a awesome shirt. One thing though these tend to run smaller than other Patagonia merchandise. I find this true in all the Cap 3 stuff. So order a size up. Also, I give a HUGE thumbs down to the Cap 3 crew. I have two and both have had the neck seems come undone. The zips seem to have no problem.

Great for running in 40-ish degree weather. Capilene is great. Wicks sweat perfectly. This one is also nice just as a layer for colder days.

This is one of the most comfortable pieces of clothing i own. The C 3 allows great warmth and protection from cold environments. Recently on a backpacking trip i used as a mid-layer/outer - layer over Capilene 1 T, this was a good combo which served to protect me from the cold but also allowed me to move freely with my pack without getting overheated. I have also worn the "C 3" on colder snowy ventures were once again as a base-layer combo with C 1 crew, Arc'teryx gamma Ar soft-shell jacket, and Theta hard shell it worked great to keep me warm and happy. I have on occasion found the "C 3" to be versatile enough to be worn out around town and on Campus ( Im in college ), i have received several complements on both the way it fits my body and feels. Only complaint is that it will get very stinky after prolonged physical activity. all around good buy will most likely purchase another.

Great baselayer for aerobic winter sports. I even wear it alone for those early morning runs where the air is still cool in the higher elevations. Fit is athletic, size up if you're looking for a looser fit. Cheers.

I used this shirt to hike the 2,178-mile Appalachian Trail. It holds up very well, dries quickly, kept me warm, and I use not other base layer bedies this. Cannot give it enough recommendation.

I bought a white Capilene recently then promptly turned around and bought another. Without doubt my favorite shirt, I wear it every day. Perfect fit, very comfortable, nice high collar. Wonderful.

I have this shirt in black and gray. I consider it my staple piece of clothing. Can be worn in the summer on cool nights, or winter, layered with other stuff. Just purchased it in cool new brown, and green. Use it for running, mountain biking, and even to the office! New material is well worth the extra cashola.

This shirt looks really good, feels even better and keeps me warm and toasty without odor issues. I just ordered another one.

Wore this for ski trips for 2 years. Does the job well. People say it runs small, but its a base layer, it has to be tight so it wicks properly. Ziper on the chest is nice so you can vent your core easily.

One complaint is that after 2 years it did start to fray on the chest where my suspenders are. I don't think this has any impact on the performance however.

I like this shirt so much that I just bought a second. It keeps you warm and wicks well. I wore it, alone, as a top layer for much of the on-trail time during a 33-mile hike in 30-40 degree weather. It did get somewhat malodorous by the third day.

It's not the best for layering with other zip-necks though. Having 4 zip-up mock turtle collars can cause some uncomfortable collar-crunch. I'm looking for a cheap cap-3 crew for this reason.

I got this for my husband for a base layer for skiing and he loves it. He is 5'11" and about 185, the medium fits perfect. He wears it from early fall until spring for anything outside. The only garment he likes better is anything merino.

Patagonia clothing is not as bulletproof as it once was. I have been purchasing long sleeve zip Patagonia knit shirts regularly for over ten years. Fortunately the last three Cap 3 LS zip shirts that I purchased last winter are still warm, comfortable and indestructible. The Cap 2 LS zip shirts tend to snag and unravel, creating large holes in the sleeves. You will appreciate the Cap 3 LS zip shirts for a long, long time.

Not quite as warm as an equivalent weight merino wool shirt, but still great. Wicks well, zipper makes temperature adjustment on-the-go easy, and fits nice & snug. Layers beautifully.

i got the cap 3 about a month ago and love it. i"m 6'1 and a 180 and the med fits great on me. it keeps me dry and toasty.

nice, soft material that is incredibly warm the minute you put it on. Looks great too!

Great layer and stuffs into your bag perfectly on those "not-so-cold" days. My first one lasted me four years. I usually wear a medium, but I had to switch out for a large. Order a size larger if you are in between sizes.

Ran in morning,15 degrees, used under a mizuno shirt. After cooling off and inside found a mysterious miniscule layer of moisture on outside of shirt. Overdressed? Kept me warm and dry, so I was very comfortably pleased

Great for an active individual. Wicks very well, very comfortable down to the 40's.

I just got back from a week of camping on the Coconino Rim just S. of the Grand Canyon. I expected mid Sept. lows in the 40s. Instead they ranged from 23 to 30. Patagonia's Capilene 3, coupled with an old (as in faithful) fleece sweater and a windbreaker, kept me comfortable. It's amazingly warm for its weight/bulk. I'll consider it a "must take" for cool & cold weather. My only gripe is the slightly-too-snug fit, but that makes it easy to wear under other layers.

got this a few weeks back and has proved to be a great insulator and baselayer. im 5'11'' and the length of the XL was perfect. im a little husky so the XL was a little snug but not uncomfortable. either way, great purchase and for the patagonia quality you can't beat the price.

The Capilene 3 shirt I bought has to be one of the better purchases I've made for athletic gear. The shirt is quite thin yet keeps you very warm on cold days. I regularly run or bike with it in 40 degree weather and it gets the job done. The only complaint I have is it's not too effective blocking the wind. Otherwise, this shirt really is a good deal. Also, it's cut very well and not too slim fit.
