Very slim fit - not what I was expecting!
If you're considering purchasing this shirt, take note that the fit is *very* slim, and also that this is considered "underwear". I was fooled by the fact that it's listed as a t-shirt, and showed up in search results for Icebreaker shirts. This is way too fitted for me to wear to work, which is what I was hoping to use it for. It's unfortunate, because this neckline is much more flattering than the scoop necklines on the other shirt options. Love Icebreaker products, but giving this an average rating because of the sizing.
Love these T's
I have about 5 of this t-shirts in multiple colors. I used them on a 3 month bike trip in SE Asia, hiking in Nepal, running and at the gym. They are soft, light weight, dry quick and never smell. I got ride of my polypro shirts that would stink so bad, I couldn't stand it. I now only wear wool. These are my favorite t-shirts and wear them almost every day for sports and/or with a skort going out for the day or to dinner. Perfect for many occasions. Recommend them all the time.
Perfect for sweater undershirt
I was searching for a slim fitting wide, neck undershirt to wear under my sweaters for this winter. I get smelly pits no matter what I do and having to wash a thick sweater after wearing it for only a few hours when it really isn't dirty, except for my armpits was frustrating. I came across this shirt, and based on the reviews, decided to order a small and a medium to see which one would be the best next to skin fit. Happily the small fits perfectly. It is very thin and very lightweight. I wouldn't wear it on its own as a T-shirt but for my purpose of wearing underneath sweaters for the winter it's perfect. For reference I am 5'5" 145lb with a slim athletic build. The reviews were so mixed on whether or not it was too tight or too loose from people with similar measurements that I decided and take advantage of icebreakers free returns to send back whichever had a looser fit, which was the medium.
Icebreaker blend lacking in quality
I bought a few of these four years ago and I would not recommend them. They were expensive so I will wear them out, but they are itchy and hold onto odor. After a few other purchases, I now avoid Icebreaker’s merino blends, because the itch doesn’t improve over time and they tend to get permastink (which my blends from other brands don’t, even those with more nylon and less merino).
This is a repeat buy for me
[This review was collected as part of a promotion.] I love these t-shirts for all my active sports. No matter how much I sweat, these shirts never smell. I've switched over all my polypropylene to wool. These are light weight and super comfortable. Great for layering too. I also use the long sleeve version for another layer. I'm always cold on airplanes and can regulate my temp based on my layers. Love love love these t's.
I love this and want another now!
[This review was collected as part of a promotion.] I bought this specifically to layer underneath sweaters during the winter. Now, I'm realizing that I can use it during all seasons because it's so light and breathable. It's a snug fit, but that's exactly what I wanted so that it's not too baggy. I'm looking into buying another!
This is my go-to undershirt and helps me thermoregulate
[This review was collected as part of a promotion.] I love icebreaker and wool in general. I own several icebreaker t's and these have the nicest fit, very flattering without being too tight. They are perfect under a sweater and also with a blazer.
Not my first or last siren.
[This review was collected as part of a promotion.] I have several Siren tshirts. I bought this one because, horrors, I lost my last one on a trip! Cannot be without a black merino tshirt ever!!!!! Perfect year round in the Pacific Northwest.
Great color. A bit snug
[This review was collected as part of a promotion.] Great color. Its my sleep shirt in warmer months. For XL, I wish it was a bit larger. Normally I wear L and wanted a loser fit but it still clings to me.
I have several in different colors.
[This review was collected as part of a promotion.] I'm 4'11" and 92 lbs. The x-small for perfect. I can also wear a tanktop underneath if needed. Very comfortable and lightweight. Very flattering too.
