  • Greatest base layer
Color: Black Size: Large
I lived in Montana where winters went far below 0. Icebreaker layers are the very best Marino wool products I’ve ever worn. This one is thin for comfortable layering over a t-shirt & under a sweater for cozy, toasty warmth without itch or bulk. Great company. Pricey but often on sale & worth it.

  • Worthwhile
Color: Midnight Navy Size: X-Large
It fits well and is very comfortable other than it is ever so slightly itchy. It isn't a deal breaker. Unless you have very sensitive skin it shouldn't be an issue. I will likely buy more of them. 11° here this morning and with other layers I'm as close to warm as I could be. I ordered XL.

  • Great quality! Worth the price.
Color: Black Size: Medium
I can’t wear most wool against my skin, but the upper-level icebreaker items are worth the money. Durable, warm, comfortable. If I get itchy, I know I’m overheated! The rest of the time I’m warm and comfy.

  • Warm & comfortable good looks
Color: Black Size: X-Large
Fit well, soft merino wool and a good base layer or on its own with its basic but good look. Next try their hiking socks if Amazon would stock them I’d buy more as I love them . Wear well, warn wick moisture easily and are comfortable too.

  • Fits perfectly, not too slim, not too loose
Color: Black Size: Medium
I bought a icebreaker T and wasn’t super happy with it for the price. I was hesitant on buying another icebreaker product but the price went down so far that I couldn’t pass on the deal. This icebreaker shirt was so much better. First, it’s soft and doesn’t itch. (Other wasn’t super soft and was a lil itchy). The medium fit me perfectly. Not too slim and not loose either. We’ll just have to see how well it performs when I travel. *real time review edit. Had to downgrade a star. The stitches in the shoulder and under the arm itch as you walk. Still not a deal breaker, but a downgrade ... show more

  • Surprisingly warm
Color: Black Size: Large
I was a little worried about how thin these are, but they are incredibly warm. I have a few now and these are form fitting and great for winter (or maybe fall/spring in cold climates). These pack well for trips and have zero bulk. Glad I have them.

  • great quality and versatile base layer
Color: Midnight Navy Size: Medium
compared to other good quality brands like smartwool, mammut, or kuhl this base layer stands at the top in every respect: functionality, fit, comfort, construction, etc. i bought a navy blue one and used it all winter last year: no fading of color, no getting bent out of shape, and no chaffing.

  • Perfect wool layering piece
Color: Gritstone Hthr Size: Large
My son loves these and this is one of his favorite brands. He lives in a cooler, damper climate. These are great to layer underneath other shirts for warmth.
