    The Icebreaker Women's Long-Sleeve BodyFit 150 Siren Sweetheart Top is so light and soft that it feels like you’re wearing a cloud. Merino wool gives this casual baselayer a breathable feel that fights odors, and it has a touch of Lycra that offers some comfortable stretch. All year long, this ultralight V-neck top flatters your figure, whether you’re running around town or relaxing on the couch.

    LOVE LOVE LOVE this top

    • Familiarity: I've put it through the wringer
    • Fit: True to size

    I was hesitant about a sweetheart neckline for a baselayer, worrying it might be too drafty, but this actually comes fairly high up on the chest for a good amount of coverage, and actually feels just as cozy as my crew-neck baselayers. SUPER warm, not at all itchy or stuffy...I got the green stripe color, which looks fantastic under a dress, vest or anything else you'd want to wear over it.

    Comfortable and Warm

    • Familiarity: I gave it as a gift but have feedback to share
    • Fit: True to size
    • Size Bought: Large

    Provided consistent warmth during a weekend trip to the Oregon Coast in April, windy with highs in the low 50s. Itchy before the first wash but softened up significantly after that. It didn't get washed for 4 days and didn't stretch to the point it was unusable as a base layer... or stink! Would not recommend as just a plain shirt as advertised.

    Just can't get enough!

    • Familiarity: I've used it once or twice and have initial impressions
    • Fit: Runs large
    • Size Bought: Small

    Love this piece, I could own one in every color. I went w/ a Small, though am typically a Medium and it fits perfectly. Slim, next to the body, sleeves and length are long enough - I could layer with it every day. I think a medium would be slightly baggy in the waist and arms. The wool content is soft, with a bit of stretch.

    awesome if it fits

    Durable and comfortable but they've changed their sizing so true extra smalls are left out in the cold. So I'm left hoping my old one doesn't wear out because I can't replace it!

    Wife (almost) cried when she lost it

    • Familiarity: I've put it through the wringer

    My wife and I hiked the Napali Coast trail in pretty much a constant downpour. She wore this shirt for the whole two-day trip and said it was the perfect piece to have with her while we braved the elements... My wife has been eagerly waiting for this shirt to get back in stock since she discovered that she left hers Kauai. Oops.

    Be warned that the fabric of this shirt is THIN, but that's actually the main reason my wife says she loves it. It can work as a very light single-layer, or a versatile base-layer to put warmer layers on top of... She also says she likes the neckline because it is a lot more flattering than a traditional crewneck.

    A versatile wool base

    I was looking for a merino wool base layer that I could also get away with wearing out to dinner, this top works for both. I like the wider neck and cut of the top. I got the black in medium, like most icebreaker tops I would say it runs small as I am often a small. I have no issues with the wool itching. I want to order the other colors!

    Great for activity or everyday!

    I'm a sucker for a good thin long sleeved layering shirt, and the fit of this one was great! I tried this out while playing disc golf in dry 37-40 degree weather on a windy day. I wore it as my bottom layer under a fleece and a shell and it stayed put and didn't ever ride up! I like the longer length of the shirt and the longer sleeves that go past my wrists. I'm 5'6", 125 lbs, a B-cup, and the small fits perfectly! My only issue was that it was a tad bit itchy at the crease of my elbow, but I'm hoping that will stop after a few washes!

    Get it, Got it? GOOD!

    So I haven't yet taken this baby out on a ski tour yet since its not winter. However I have worn it on some cold fall nights and it does awesome! It was stiff at first but giving it an initial wash really helped. Climbing outside in this shirt is perfect for those cold fall days in the mountains. This top would do well camping and hiking as well. It not only kept me warm but dry and that is always super important especially when dealing with the cold. Not only does it have outdoor uses it can be worn as a casual piece as well. Paired with some cute jeans you can totally rock this at a get together. The fit is super cute and slimming. I'm 5'4" 120lbs and the size Small is perfect. If you want it to be "to the skin" I would suggest getting the XS. I highly recommend this top to the ladies out there who are looking for an awesome base layer for the fall/winter. I look forward to using it in the winter and will update my review when I fully test drive this top out.
