Everyone should have a base layer like this!!


  • Very breathable
  • Does not hold body odor
  • Soft and comfortable
  • Dries fast


  • Expensive

I never thought I would ever spend $50+ on a base layer. I am glad I did!!  

I have used this base layer for over 4 years now and it is still good as new.  

I wear this shirt while hiking as a T-shirt when it is warm and as a base layer while hiking when it is cold. It is very comfortable and soft. It is very, very breathable. It wicks sweat away from the body and sweat evaporates off it very fast. The main thing I love about this base layer is it minimizes friction between a heavy backpack and your body.   

It is just a simple shirt that provides wonderful functionality. I highly recommend every backpacker/hiker use a shirt like this as a base layer.

This is a great lightweight merino wool layer. It works just like the best merino wool baselayers are suppose to work: Like a thermos.

From the moment I put it on I could feel the warm air layer envelop the skin. Because it's only a Merino 2 (not a 3 or 4 - it's a lightweight, for sure) it doesn't hold the heat in by itself when the temps dip below 45F. I wouldn't wear outside without more layers under 50F in less than moderate activity.

That said, this Patagonia merino baselayer regulates bodyheat better than Patagonia's similar Capilene (synthetic) baselayer. I rarely sweat below 70F in heavy activity, and I can feel the heat coming off the fabric when I'm indoors in overheated rooms.

I highly recommend this.

There is slight itching in the wool after a while during the first few wearings. Either it goes away or I've gotten used to it. It's so subtle, I thought twice about mentioning it.

Worth the money past any synthetic baselayer, for sure. And it doesn't smell quite as bad as synthetics, either.

Stay warm and comfortable in cool-to-cold conditions in the Patagonia Merino 2 Lightweight Crew which is made of 80% merino/20% Capilene fiber blend.


You're half a day late, the bus offers standing room only, and it feels like the Carter administration since last you slept. Yet, in spite of it all, you're dry, comfortable and up for more. This go-anywhere crew combines a comfortable feel with wool's inherent benefits for going places: softness, natural odor control and warmth. Our most versatile merino baselayer fabric, Merino 2, keeps you dry and comfortable during active pursuits in cool to warm conditions. It breathes, regulates body temperature, stretches and has a great warmth-to-weight ratio. Our wool comes from non-mulesed Australian merino sheep. We slow wash it for softness and shrink-resistance without the use of environmentally harmful chlorine, and blend it with 20% polyester (100% recycled) for increased durability, resilience and moisture management. The raglan-sleeve design and offset side seams lie smoothly beneath pack straps. Machine wash cold; machine dry at low temperatures. Featuring bluesign(R) approved fabric.


When you start a long hike in the early-morning chill but you know you'll be coming down the mountain under a hot afternoon sun, wear the Patagonia Men's Merino 2 Lightweight Crew. This long-sleeve baselayer regulates your body temperature--it warms you in the morning and helps keep you cool in the afternoon. It's soft to the touch and doesn't bulk up when you put your backpack on, and it stays dry so you don't have funky sweat stains from your pack.
