Merino wool, soft, lightweight and warm. Ideal for layering on a cold day. Worth the money!

Great fitting shirt that works as a good starting layer when layering clothes to stay warm or wear alone when temperatures allow. Does not itch or irritate or at least hasn’t for me. Would recommend

I purchased this shirt because I've had good luck with their products in the past, and the trend continued. Pictures attached for reference. I am 6'1" 185lbs and I purchased a medium. The sizing and fit were as expected. The sleeve length reached my wrists, and the shirt length went about 2 or 3 inches past my belt line. The shirt isn't super tight like a compression shirt, but you aren't swimming in it either. The fabric is VERY soft to the touch, and feels great against the skin. It has some give/stretch to it, but will maintain it's form. The collar fits nice, not too tight against the neck. I found the shirt to be nice and warm, and wear it around the house instead of a light sweatshirt. I'd highly recommend for anyone looking for a long sleeve top.

I'd have given it 5 stars if it hadn't arrived with a tiny hole in it. The other one I bought was is great condition, so I gave that review 5 stars. It is soft, warm, and lightweight. Got it on sale, which is why I gave this brand a try.

Get this one.  Bought MEDIUM.  Me:  5'10", 185.  41" chest.  Shirt size 16.5x35".  Sleeves plenty long, and I cuff 1".  Perfect snug (but not tight) fit.  Non itchy Merino wool.

Did not like that waist doubles its width during the 1st wearing. Not the 1st washing but the 1st wearing. I own 7 other brand name wool³/wool blend⁴ tops and none of them have stretched even after multiple wearing and washing. Will not buy this brand again.

Definitely want to get more. The value compared to a “high end” Track Smith merino wool is not even close. I find this much higher value based on what you get for the cost. Would recommend.

Last winter I was wearing cotton t-shirts and often was feeling cold. This winter I wanted to change that and bought the shirt to see whether I would be warm and comfortable. I bought size L and have been wearing the shirt twice. The fitting is good and you almost do not feel that you are wearing it and most important I was not cold. I have not compared it with other brands, but I can recommend it. The only thing I would change is to remove the laundry label and print it instead.

Das langarmige Unterhemd erfüllt genau meine Erwartungen hinsichtlich Paßform und Isolierwirkung, bei gleichzeitiger Ableitung des entstehenden Schweißes. Keine Geruchsbelästigung, auch nicht nach 2 Tagen tragen!!

Achtung, obwohl im Bild und in der Produktbeschreibung sowohl Top als auch Bottoms steht, bekommt man nur den Top.

Insgesamt ist das Unterhemd nicht schlecht, jedoch auch nicht komplett überzeugend.Zum einen fällt es sehr groß aus, also lieber 1-2 Größen kleiner bestellen. Zum anderen ist es qualitativ den Merino Unterhemden bekannter Marken etwas unterlegen. Des Tragegefühl ist nicht schlecht, aber auch nicht so anschmiegsam wie bei der bekannten Konkourrenz. Das Material wirkt auch nicht ganz so stabil, Langzeiterfahrungen zur Haltbarkeit habe ich jedoch noch nicht.Positiv ist, dass das Unterhemd den Körper gut warmhält, kaum Gerüche annimmt und schnell trocknet.
