SmartWool Microweight 150 Crew Reviews:


I moved from living in an arid scrubland with nearly no humidity and big temperature swings to living right off a salt flat that is usually warm and clammy or cold and clammy. Not only is this environment very inclement towards clothing (things just melt when washed) it's very hard to get comfortable and STAY comfortable.
Smartwool seems to hold up well to the wash (and doesn't need to go in as often!) and it seems comfortable through more temperature profiles than I expected. Smartwool isn't just a smart product, for me it's a smart buy -- I simply can wear it more often than I can other products. (The pieces, since they are intended as gear aren't what you might initially think to wear to the office or to dinner, but it's easy to camouflage them.)
Word to the wise -- out of the box the product really feels weird. I think it's starched. Once it's washed it fits better and feels like silk. So don't compltely judge it into you'll washed it once or twice. (I use the Eco soap from Costco and get fantastic results. I don't think you need anything special, but I wouldn't use something harsh like Tide or All.)

I love Smartwool...I've done my best to convert my entire wardrobe, and this shirt has stood up to expectations. It's light enough to be worn in the 90 degree heat, but kept me from freezing when the temperature dropped to 50, the wind kicked up, and I was already sweaty.
I wish that the shirts were either slightly less expensive or less prone to's a bit sad to tear a hole in a 60 or 70 dollar shirt (and all of my shirts have small holes in them, but we did quite a bit of hiking through vicious plants). I'll probably address the problem by buying another set of these to wear when I'm not on the trail and save the damaged ones for the woods.
The grey is basically as seen in the picture: nothing too exciting. I have the microweight v-neck in violet; it's quite a pretty color and it has a nice subtle pointelle pattern in it...I really like it.

I wish all my clothes were merino wool! The breathe-ability, fast drying, and odor-less wool has really got me addicted! This is my favorite layer, I wear it next to skin and will top it off with a flannel for those chilly fall days. This layer is great for any outdoor activity you can think of! No tumbholes in this NTS layer in case you were wondering. Fit is perfect, true to size! Colors are prettier in person! Can't wait for this layer in the wintertime!

This shirt is supersoft, very thin without being sheer, and nicely fitted. I've worn it as an extra layer in the mornings in the summer and love it. Haven't had it for winter hikes, but it has the potential to be a great baselayer. I'm 5'9", 170, 36C and the large is great. Bonus, the mineral color is lovely (not as neon as the picture makes it seem).

I love Smartwool and own half a dozen tops. The microweight is kind of thin, though, so you gave to be careful what color bra you wear underneath if you're going to wear it by itself. That being said, they are very soft and warm. I'm a size 6 (38-28-38) and the medium is perfect. Order a size down if you like a snug base layer.

I am in love with these wool shirts. I am amazed how they do not hold odors & how easy to wash out drips & dirt. The temperature regulating from hot to cold is wonderful. This particular one is light weight & looks a bit like a thermal shirt. I am happy with it.

Hard to tell but if you zoom in on this product photo it has a lovely pattern to it. A great base layer from on to off the hill!
