Wear the Patagonia Men's Merino 3 Midweight Zip-Neck Top as a layer in cold winter weather and stay warm and comfortable. This baselayer regulates your body temperature in cold temperatures so you'll stay cool when you hike up to the top of the powder-capped peaks and stay warm when you're dropping down into the shady side of the mountain. When you get to the chairlift, unzip the fleece so you can let out a bit of steam while you relax until the next run.

  • Merino wool and polyester blend gives a soft feel, naturally controls odor, and wicks moisture

Keeps me Warm !!

  • Familiarity:I've used it several times
  • Fit:Runs small
  • Size Bought: Large

First time to buy a Merino Wool Product. Because of the slim fit I had to go up a size. Keeps me warm without overheating. Seems to be a little longer then others similar items which I really like. Even though it costs a little more then other brands it's a product that really lasts. I still wear my Capilene top from 18 years ago...

Not Worth the Price

I actually like the fit and feel of this top but after minimal use it started to pile on the sleeves and trunk. For this price, it shouldn't start piling so soon. I've owned it for about a year but have only worn it around 10 times. The piling is so bad that I stopped wearing it by itself or with a t-shirt because it looks so bad. I took great care of it too, only hand-washing and air-drying. I'm surprised nobody else has put this in their reviews for such a pricey piece of clothing. I would never buy this again.

The Real Deal

I couldn't be happier with this product. As usual, patagonia goes above and beyond with function and style. I've used this on multiple fall backpacking trips this fall and it's perfect. Keeps you dry from sweat, and warm without feeling "stuffy." I've also used it the last couple of weeks for hunting to replace my old Under Armor cold gear and it did wonderful as well. Kept me warm yet unconfined. If you need a great baselayer, I can't recommend this enough.

New Favorite

  • Fit:True to size

love wool, love patagonia base. This is my favorite winter base layer, I never want to take it off. Not too tight on me, I can wear a t-shirt under or a fleece over and it not feel too tight. super soft. Im sure it will last, great build. Can't wait to put it through more than just some day hikes. I won't travel/ hike without it. If you don't have a r1 hoody (or something comparable) get the hoody version of this. I got this for run, bike, hike & travel. I always feel warmer in wool than poly.


  • Familiarity:I've used it once or twice and have initial impressions
  • Fit:True to size

I put this on along with Patagonia R1 Fleece Hooded Pullover on my recent Grand Canyon trip. Since it was going to be cold at times and yet I didn't want to put on anything bulky, I decided to wear this with the other on top of it, and it worked out perfectly as I expected. In spite of the fact that it is a base layer, I didn't have any problem wearing it like a sweater, which fit perfect to my body. During 3 nights and 4 days of backpacking at the bottom of the Grand Canyon I put this on every day. I love the fact that it dries so quickly and feels so comfortable in it. Not much of weight also helps although I wore it while hiking every day, instead of carrying it in my pack, but along with Patagonia R1 Fleece Hooded Pullover, I seriously didn't have any problem on the trail.

snug, non itchy

It is pricey for a base layer. But it works excellent as a fringe season (35-50f) running shirt. The thumb loops are quite thin and i typically only use them to hold the shirt in place if i am pulling another shirt on top. Being able to use it 5-10 times before a wash is great. The shirt is not at all itchy as some other merino long sleeves can be. Fit on a large for me 6'3 195 is great. Worth it only if you plan to use and abuse it.
