Icebreaker Women's Siren Sweetheart Top

[This review was collected as part of a promotion.] I love the neckline and figure hugging fit of this tee. I wear it alone but it would also work great as an undershirt during cooler months. The feel isn't as silky soft as some of my other Icebreaker clothing but I don't find it itchy at all.

[This review was collected as part of a promotion.] I use this shirt for Hiking. It's cool in the summer and comfortable. I don't know how it works, but somehow it keeps the sweat from getting stinky. One thing you need to know about this brand is you have to wash it on gentle setting. Also, I ordered a size bigger than I might ordinarily order cause I didn't want it to be too snug. Large was perfect when medium is usually what I order on other shirts.

[This review was collected as part of a promotion.] It is so nice to hike and not have a sweaty and stinky top

[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.

[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.

[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!

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.
