Product Reviews
Rated 5 out of 5 by from Don't Change a Thing Plain and simple, if Smartwool ever changes a thing about these shirts, especially, the 100% Merino Wool fabric, I will discontinue buying Smartwool. These shirts are great in every way just as they are. I have been wearing the 250 weight for several years and they have performed extremely well. For 2017, I noticed that Smartwool has changed the wool fabric content on their 150 models. I will not purchase the new versions of the 150 weight shirts. I hope Smartwool reads this review and return to the 100% Merino Wool shirts.

Rated 5 out of 5 by from Fantastic Product Recently took this on a 10 day vacation as my only "sweater." Wore almost every morning and night when it was cooler and it did not require a single wash. Smelled great upon returning to the US as well, after 10 days of wear and 2 10-hr flights. The wool's ability to regulate temperature was a life saver. The only complaint is that after 10 days of wear, the material was noticably "fuzzier" than before. It will remain to be seen how this holds up over time (this was a relaxing vacation and no excessive wear and tear occured). While it will still function, a fuzzy appearance may not let it tranistion to dressier occations or dinners out.

Rated 5 out of 5 by from Phenomenal! If I had to have 1 shirt. I needed a base layer for all kinds of activities this winter and, after my huge success with the 150 shirt, opted for this 250 base layer. This thing is great, I wear it until I can't anymore. It's dressy enough to wear as a regular ( functional ) shirt to work, restaurants, out n' about and it also is going to be my go-to shirt for colder backpacking or winter sports. If I had to have 1 long sleeve to survive the world, I'd choose this one. The only downsides I've found to It is that the shirts are a little bit long, so I'll roll up the bottom of the shirt to get it aligned with my torso ( I'm 5"10 ), and that the material started pilling minimally from the rolling within the first week.

Rated 5 out of 5 by from Completely Satisfying!! Love these base layers. Recommended to several friends who are now loving them as well! I'm 6'7" tall and the body and sleeve length are perfect! I chose xxl as I like the feel of a little oversize gives me. They wash really well, don't smell, seem to adjust well to temperature variations through the day and evening. The colors are rich. The zippers work really smoothly. The quality of the wool and the sewing is as good as it gets! Since acquiring my first one, and having worn their socks for years, I now wear their boxer briefs which are also excellent. Thank you Smartwool for doing it the right way. A bit costly but so worth it!

Rated 5 out of 5 by from My third one, when there's new colors I'll get another! [This review was collected as part of a promotion.] This is my third 250 1/4 zip and they're pretty much my favorite clothing item. Soft, comfortable and breathable, they are fantastic for layering in colder weather or wearing as a single layer on spring and fall days (I run cold and I'll wear this up to 70 degrees). I'm slim - 6'2", 165 lbs and have a hard time finding clothing that fits my long arms that isn't too big in the torso. The size medium fits me well in the arms and isn't baggy. I ordered my base layer SmartWool T's in a size small for a more second-skin fit.

Rated 5 out of 5 by from Excellent base layer/stand alone piece for every activity I bought this piece to wear under my hard shell while biking to work in sub-freezing temperatures. In that regard it excels as it keeps me much warmer than wearing several heavy layers while preventing overheating when I get going. Since purchasing I've also used it hiking up to 70 degrees (F) and relaxing around the house on chilly nights. For both uses it is quite comfortable and performs excellently. The fit is rather generous. I ordered a large initially (I'm 5'9" ~170lbs) but it is rather loose. Its still comfortable but not the greatest underneath tighter jackets as it bunches up. I've since ordered a medium and that is more of a tighter base layer like I was hoping the large would be. Just keep that in mind prior to purchasing. I cannot comment to the durability as I've only had it about 2 months. So far it just has minor pilling where the belt of my hiking backpack rubs my kidneys.

Rated 4 out of 5 by from Quality gear Got this for my husband for Christmas. He had purchased a merino 3/4 zip from a high quality hunting brand and loved it so u thought I woks get him another one. This shirt blows the other out if the water - it is softer, warmer and fits better. We are incredibly active all year round in all conditions in the chilly and high elevations of western Wyoming and since he revived it he hasn't taken it off. We will be buying more and for him the only downside is it doesn't come in camo! Already we have recommended it to all our friends and he's wearing it out ice fishing today (9° and snowing)

Rated 5 out of 5 by from Excellent Product from an Excellent Company-highly recommend I bought this product as part of my hunting and backpacking cold weather base layer system. I am 6'0 218lbs with am athletic build and the xl fits me great. The 1/4 zip is nice for letting my body breathe on long hikes, but can be zipped up when I am stationary. Overall I highly recommend and will purchase similar items throughout their product line.
