Discontinued. From Icebreaker's 320 RealFleece line, the Igloo shirt is the perfect layering piece, thanks to its temperature-regulating merino wool, which also happens to be ultrasoft, itch-free and odor resistant.

    Reviewers say this jacket is cut strangely through the shoulders, and I understand what they're talking about - the chest and shoulders are very fitted. I am a solid size S in IB (and other brands). If I had wider shoulders or a larger bust, this S might be too tight. (I'm 5' 5", 125lbs., athletic, and I like my clothes to fit closely.) It felt a tiny bit restrictive in the shoulders when it was brand new. But after wearing it for a few weeks, the fabric has softened in all the right places, and now I don't notice any restriction whatsoever. Fits me like a glove! And the 320 weight is much warmer than the 260 I have. Super happy.

    This Igloo shirt is the perfect layering piece, thanks to its temperature-regulating merino wool, which also happens to be ultrasoft, itch-free and odor resistant. I love to layer it with a shell and i am so warm with out the bulk of a winter jacket.

    I love this Shirt. I wear it all the time. It is great for layering. Merino wool is brilliant! It is thin AND warm. I have so many of the Icebreaker items and continue to add to the collection. They run a little small, so I buy a size up.

    I adore Icebreaker. I"ve always wanted an IB jacket, but didn't think I could afford one. Took a chance on this jacket, and as several others have mentioned, it has a very odd shape.
    the fabric is truly lovely. Light, warm, totally non-itchy
    I ALWAYS wear a "small" in IB clothes, but BUT the shoulders of this jacket are strangely tight, as is the chest. The waist and length are perfect. I'm going to keep it, Overall it's "ok". I really wanted to love it, but I don't.

    i used this under a down vest and over a thin wool base layer in 30 to 35 degrees in washington state. It wasn't incredibly warm, but warm enough. It's form fitting and flattering. The shoulders are not made correctly as other reviewers have stated. It didn't bother me enough to return it's just that for the price it can be dissapointing when you expect to get something constructed better, even at the discounted price. I am normally xs. I am 5 4, 106 pounds, 25 in waist, 32 c... the chest was a little restrictive. You can only layer one thin piece underneath.

  • “Is the fit the same as the hooded igloo?”
    Asked by hiker from san francisco on 5/7/2011 12:00:00 AM
    • It should have a very similar fit if not exactly the same.
      Answered on 5/10/2011 12:00:00 AM by Anonymous from Unknown
    • Yes - I bought both - the only thing is, collar kind of sticks up toward the chin on the non-hooded one, as the hood pulls that down due to its weight. That will probably soften a bit with washing

About Icebreaker

Crafted using only the finest merino wool grown in New Zealand’s Southern Alps, Icebreaker clothing is known around the globe for its incredible comfort and performance. Unlike synthetic fabrics developed in a lab, Icebreaker merino wool is grown, cultivated and field-tested in the mountains. Designed to offer exceptional comfort during a range of outdoor sports, Icebreaker underwear and apparel naturally resists odors, regulates body temperature, wicks moisture and dries quickly. Superfine New Zealand merino wool is also much softer than traditional sheep’s wool, which means no itch. Icebreaker socks, long underwear and base layers also come in a selection of weights to keep you warm without overheating. Ready to join the merino revolution?
