Great quality! Worth the price.
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.

Greatest base layer
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.

Warm & comfortable good looks
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.

There is a Reason for the cost!
This shirt is the best base shirt EVER! Yes, it’s expensive, but I promise, it is worth every penny … and you will have this shirt years from now!

Surprisingly warm
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.

200 Oasis LS
Good base.. not as warm as I hoped it would be for the amount paid, but it is very comfortable and fits well. (I'm 6', 180lbs, size medium)

great quality and versatile base layer
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.

Warm and Comfortable Out in the Cold
We were headed to Scotland in mid-September and outdoor sight-seeing. Did not want to take any chances on the weather. Decided to buy three shirts and three leggings. Best decision. Warm and comfy day and night.
