Review: perfect gift - Son was very surprised and happy with weight and quality of the 100% merino wool shirt. Also that it was long in length and arms.
Review: extremely high quality. I know it seems pricey, ... - extremely high quality. I know it seems pricey, but it won't when you receive the product and see the quantity of wool and the fit and finish. I have no idea how this product is made so inexpensively. Apparently there's a wool factory somewhere in China that is very advanced and efficient. I bought it for a 12 hour summit day in freezing weather. Now that I have it, my only concern is that I'll be too warm while climbing, even possibly with just a rain shell over it. Even if it proves to be overkill for climbing, it will still be extremely valuable to me for cold camping.

extremely high quality. I know it seems pricey, but it won't when you receive the product and see the quantity of wool and the fit and finish.

### ⭐⭐⭐ Lasting quality isn’t there
*by T***Y on April 23, 2026*

Maybe it’s just me, but I use woolite, I wash on delicate cycle, I tumble dry with no heat inside laundry bags that are for delicates and they still got tons of little holes in them in less than a year. For the price of these I think it’s worth getting a cheaper brand
