Beautiful shirt
Beautiful shirt. Washes well and looks great.

Nor real wool - not performing as it should
I am fond of wool underwear and use them constantly. This item advertised as wool was not sewn very professionally but I was open to overlook this if it performed well. Unfortunately, it did not perform. It was not warm to the touch when wet and tended to have an odor much faster than my other brands wool underwear. Since I wanted to check, I tried to burn a small piece - no smell of burnt hair emanated and the material behaved like a cotton blend. This makes me think it is not wool

The socks worked beautifully. I had crushed my ankle and the merino socks were pressure free.

Not comfortable and seem like they may not even be merino wool. They buch up and have no structure to them. They are loose right of the package like they are already worn out.

They’re holding up okay, I’ve worn them for about a total of a week and the waistband is separating. It’s holding out for now though. They feel fantastic and do exactly what wool unders should do, just concerned about how long they’ll actually last for the cost of ONE pair.

I bought this product to have a clean night shirt when backpacking. I am 5.9 / 150 lbs and usually wear a medium. For this shirt I specifically chose size large, for more comfort during the night the fact that according to the sizing chart the large was to be 26.8 inches in length. The real length is only 24 inches which defeats the purpose I bought it for. I am keeping the shirt because otherwise it is very soft, breathable and light, really a great product that feels like a second skin. I have other Merion Tech products and love them all, but the missing 2.8 inches are really disappointing.

The colors are vibrant, the feel amazing. I will be wearing these on the trail and to work as well. This is very nice wool. I quite like the socks. Not too bulky, not too thin.
