It’s the perfect material to wear for summer. It’s light, not itchy and comfortable to wear. And of course, the price is affordable. Will buy more for another color.
Great product ! Merino Protect is my go to merino wool items now. For fitted size Large is good for me-175lbs, 5’7”, 36G, for looser fit must but XL.
Comfortable and accurate sizing. Love the color!
I bought this t-shirt in 3 colors, and I couldn't be happier. They are bright and soft. They dry very quickly and will be perfect on an upcoming month-long vacation.
I prefer the 200 weight, i wish they had a regular all black V-neck. This one i keep having to pull down so it doesn't strangle me. I really prefer a very loose neckline.
