Pull on the Stoic Men's Alpine Merino 150 Bliss Shirt, and suddenly a sweaty hike in chilly weather feels like just another day in paradise. A smooth, comfortable combination of merino wool and synthetic fibers gives this next-to-skin layer the power to control moisture and help you keep a nice, even body temperature whether you're hiking, running, or climbing. You get the best of the luxury baselayer and a performance-driven top, and that's hard to ignore.

  • Alpine Merino material combines soft merino wool with quick-drying polypro
  • Merino wool is naturally breathable, resistant to the bacteria that causes odors, and it provides light insulation
  • Polypropylene fabric improves overall garment durability and wash-cycle life
  • Next-to-skin fit keeps this shirt close to your skin to keep you warm and to help move moisture away from your skin so you feel dry
  • Thumbholes keep the sleeve openings pulled over the back of your hands for warmth

Good for everything

  • Familiarity: I've put it through the wringer
  • Fit: True to size
  • Height: 6' 0"
    Weight: 170 lbs
    Size Purchased: Medium

I use this as a base-layer and also as just a casual shirt. Does fine in warm and cool weather. I was a little in between sizes and decided to go with a medium for a more fitted fit. I've been sure to not dry it and it's worked for me, with the good Stoic fit.
Good moisture and odor management. I like the merino blend. Soft and comfortable.

Size help

  • Fit: Runs large
  • Height: 5' 9"
    Weight: 145 lbs
    Size Purchased: small

Just got this item (super fast shipping, thanks Backcountry!) and wanted to comment on size. I'm 5'9" 145 lbs, slender overall build. Stoic's chart says I'm a M but based on these comments I got a small and small fits me perfectly. Neck fully zipped is comfortable but protected, chest tiny bit loose (when zipped) for freedom of movement but not enough to cause bunching. Sleeves are long but meant to this way, when using the thumbholes sleeves cover half of my hands perfectly.

Feels less soft than expected (forgot it's a merino blend) but also feels more durable than expected, a tradeoff I'll take. Gave it 4 stars for fit/finish and how I'm impressed thus far but again I haven't used it under real world conditions, will try to update this when I can. 6/6/2015.

Does it shrink?

it will shrink a bit if you put it in the dryer, but not as much as a 100% merino product will. I hang dry all of my merino base layers just as a precaution.

Unanswered Question

I'm 5'10 and 165 pounds. I would naturally go for a medium but with the reviews thus far I'm not sure. My shoulders have never fit in a small, which is my concern for sizing down. suggestions?

Is there a women's version?

Up to which temperature could you comfortably wear this shirt? How hot is too hot for it?


That is really up to you and what you are doing. It is a pretty thin material so I have worn this base layer in the 80's and 90's while fly fishing to keep the sun off. However if I was doing something active it would be way too warm. Temp ratings don't really exist for clothing as there are too variables. However this is a great light weight long sleeve base layer. It's a great fall-spring item. If you have any other questions or would like to purchase the shirt contact me below.

Very long sleeves.
Overall runs a little large, I'm 6 ft tall and 175 and it fits slightly baggy. Good light layer though.

Not true to size

  • Familiarity: I returned this product before using it
  • Fit: Runs large

I really like the fit of my other XL stoic baselayes, (Merino Bliss 150)
I thought it was a safe bet to order an XL in this Alpine Merino Bliss 150 but found the fit to be very baggy and not like the other stoic shirts I own. Maybe sizing down to a Lg size would solve the problem but I don't feel like waisting anymore $ on return shipping.

also great for lounging by the fire....

this is actually the heavier 230 model, but the stoic merino is one of the best deals around....

I love this shirt , I have three of them but the last time I washed them I noticed one has small holes in the back of it . I have only had it for 8 months . They do run on the large , The first one I bought I got a medium It was to big so the next one I got a small and it fit great.

Great purchase

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

Purchased this on sale as a base layer for some of my cold weather runs. As others mentioned, it was a little itchy when I first tried it on. After washing it was a little better, but during my first run I never noticed anything but comfort!

This shirt is GREAT! It almost worked too good, I wore it by itself on a 48 degree morning run and was sweating by the time I got 2 miles in. It was sunny that day, but I wasn't expecting to heat up so quick. Incredibly lightweight, the thumbholes are nice for keeping the shirt comfortably in place when wearing under other layers. I originally got a medium based on other reviews- it was a bit big. In fact, the small was a little long on the sleeves but a much better fit than the medium. I am 5'9 and about 148lbs.

Also, Back Country's customer service has been INCREDIBLY awesome whenever I've had to make returns or have had other issues. They are my new favorite outdoor/fitness company.

Jump aboard the wool train

  • Familiarity: I've put it through the wringer
  • Fit: True to size

Fantastic base layer. Not too warm and not too cold. I bring this layer touring all the time. When its really cold I throw my shell over this and am good to go on the up. The chest pocket is a nice touch, though I rarely use it. The zip is large and comfortable / doesn't chafe your neck. The merino wool magic keeps the shirt relatively funk free on week long backcountry trips. Did I mention thumbholes? There isn't a thing I would change about this shirt.

Great Baselayer at a great price

Keeps you warm in cold weather and cool in warm weather.
I'm 6'1" 160lbs and the medium fits great.

Pick 'em up while you can

  • Familiarity: I've used it several times
  • Fit: True to size

I love these shirts. A great value on it's own right, but especially when they pop up on Steep & Cheap. I got one in Charcoal and Basin Blue. Both look and fit great. I'm 5'10" 130 and a small has a little room to spare.

As others have said - it's a great base layer or can be worn on it's own on days that aren't so frigid.

Pick one up while you still can.

totally agree with everything youve said.S&C is my addiction and the pop us for around $45... great deal. i even got the purple and orange cause i didnt even care

Style, Warmth, Budget Minded Enough Said

  • Familiarity: I've used it several times

Another awesome gift after adversity and one that restores my hope in high performance tech wear at low budget pricing. Love the stylish look while giving special attention at keeping warm and moisture free while skinning in the backcountry. Everyone needs at least one of these in their backcountry warmth clothing arsenal.

I'm 6' 175 lbs and the medium works out great!

Wore Out my Old Stoic after 7 years

  • Familiarity: I've put it through the wringer
  • Fit: True to size

This is the second Stoic 150 Bliss I have owned. The first is now so threadbare that I can see through it. My wife has darned it so many times that it looks nubby. BUT... it has always been my go to hiking shirt. I have worn it in 20 degree weather and in 90 degree weather. Above 15k feet and in death valley. It has seen snow, rain and hail. No other shirt I have owned has been through so much and given such superlative service for so many years. The thumb holes are a nice touch, as is the drop tail shirt bottom, and the napoleon breast pocket has always held my mp3 player.
This is one fine shirt.
Now I have to part with it, but I have a new friend -- my royal blue Stoic 150. And it is as true to the tradition of the old one as I could want.
If you are looking for a nicely priced quality merino ( with a touch of poly pro for durability) hiking shirt, then look no further. This is the one you have been looking for. I fully expect to get even more years out of this one because of the touch of polypro.
The large fit my 6'3" 180lb frame nicely.

Confused about What size to order my...

Confused about What size to order my boyfriend. He has the stoic Merino long sleeve hooded shirt and loves it. He got a large and it is bigger then he expected so I was thinking maybe medium for this one but some say it runs big and some say it fits true to size so I am not sure. He is 32 waist and prefers things a little loose ( not snug) so I would say 38 chest ( but would prefer 40 ish (so he could wear a tshirt under) 5'9, like 165.

Hey Kim,
On people stress about fit and whether one brand or one size in a brand will fit us better than another. And they obsess over that Holy Grail of clothing terms: "True to Size." I'm not even sure what that term means but we love it anyway because we all want something that fits like it was made for us. Frankly "True to Size" is a very flexible concept intending to convey something rigid.
I would not worry too much about other reviews on whether this product fits very relaxed or very trim. Those reviews can be very helpful, but it sounds like you boyfriend has had some direct experience with the brand and a large proved to be a little big on him. I would try a medium this time around.
