Merino.tech Merino Wool Base Layer Women - 100% Merino Wool Heavyweight, Midweight, Lite Long Sleeve Thermal Shirt and Socks

I originally purchased this as a base layer for a trip to Iceland. While we were there, I wore it under a Uniqlo vest for sightseeing and hiking. I have continued to wear it ever since. I bought the 250-weight shirt in charcoal in a size large. It is soft, not itchy. It fits close enough to my body to be easy to layer, but not so close or clingy that I feel self-conscious wearing it on its own. Wool is nice because it is quick-drying, doesn't trap body odor, and is breathable, making it never too hot or too cold. I was mistakenly sent a black 165-weight shirt along with the charcoal one in the same size. The lighter-weight shirt is less opaque, but it works well under other items. Overall, this was one of my best Amazon travel purchases. The socks were a nice bonus!

This isn't the first Merino tech sweater like this I've purchased. These are very nice, fine merino wool sweaters that don't feel itchy at all. I wear them as a base layer, or as a single (only layer) depending on the weather. They are perfect for trips as you can wear them next to your skin without odor for days reducing the number of garments you have to pack (always a good thing). Wool is natural warmth helping to keep your body's warmth constant and wool can get wet without making you feel cold. Because of all the qualities of wool garments, they function well in all situations, surprisingly even when you might think it is too warm for them. All of my sweaters of any style are merino or cashmere because the quality is high and their usefulness is, too. I love the fit of this sweater group. It shapes itself to your body without being "clingily", or check the size chart if you like a looser fit. Although I haven't needed it for these sweaters, I recommend a "sweater shaver" to remove any pilling that may occur on any sweater: it keeps sweaters looking brand new and only requires a few minutes to use. The colors so far are great, too!

The merino wool base layer is soft, comfortable and warm. It fits perfectly beneath a second and third layer of clothing without feeling bulky. I love the colors offered and would buy again.

This is a great, basic merino base layer that's perfect for my winter running in the Pacific Northwest. It doesn't make me feel obnoxiously hot even once I've racked up a couple miles (unlike my thicker or down layers, which I typically have to shed). Going by the size chart, I thought I might need to size up to a large, but Amazon recommended I go with my normal size medium, and I'm glad I did. I don't like oversized running stuff, and I hate when the shoulder and armpit seams are too large. For reference, I'm 5'9" tall, 158 pounds, athletic build, and the medium is great, with more than generous length in the arms and torso. Truthfully I would prefer a little bit less length in the torso, but I like things that hit just above my hips; after reading lots of reviews I've gathered that most women like things longer, so this longer length is likely better for most. This is what I would call a midweight layer, thin but not overly so, not something I would call ungenerous. It's exactly the right weight for the heat/insulation level advertised, and the temperatures I'm in right now (40s). I think it will also do well in the 30s. If it gets into the 20s, I think you might need to add a vest unless you're running very hard/hot. Included in the package was a pair of sweet thick wool socks. Love that unexpected bonus item! Just wish the socks were smaller; despite accompanying an order for a women's medium , the socks were large on my size 9.5 women's feet. Don't mean to be ungrateful, but dang! Matching the likely sock size range to the top size would be aces. Can't complain though, super happy with the fit and quality.

I really like the warmth and fit of this shirt. I wear a thin under layer with the shirt as it's not especially soft against my skin. It's a bit on the scratchy side. It's still a keeper!

Very happy with this wool base layer. I have some nice cotton pullovers that just aren’t warm enough in the winter. I add this layer underneath and I’m perfectly toasty all day. The sleeves are a tad long on me (I am 5’5”), but it’s not really noticeable or troublesome. I was a little concerned the fabric would be itchy, but I have worn it several times now with just a bra underneath and there is zero itch. It washes well - I put it on normal setting, cold with regular detergent in my machine and hang dry. I have seen minimal shrinkage. Great item!

Wore this top hiking in 11° snowy windy conditions. Bought the 250 and wore it as my base layer. It is 100% Merino wool and it was warm and soft. The sleeves and length are perfect. The design is very pretty. Included in the order is a free pair of Merino wool socks. As an avid hiker in all weather, I will ne buying more as the price is fantastic for the quality.

Not super itchy, but you can tell it's wool. However, the main problem - XS is HUGE. It's very stretchy, so honestly an L can fit in it. Returned.
