Quality constructed thin wool-blend socks
I’m a little puzzled by some of the other reviews. First of all, these appear to have been designed and are described as lightweight socks; their thin profile is on purpose. They are not thick wool winter weight socks. Second, the material blend is stated in the description, so there should be no surprises there. I love thick wool socks, but not when summer trail temperatures are in the 90s by midday. These are great, lightweight socks that protect your feet without causing overheating and dry quickly. They run cooler than my darntough socks. They are a good deal at their regular price and a bargain when they’re on sale.
Not all wool mostly "recycled bottles".
This is not wool. It is 35% wool, very misleading.
Ok but prefer better quality.
These are ok, but I decided to go with high quality product from SmartWool.
Good socks, good price! 🧦
This is my first pair of merino wool socks. The price is great for someone that doesn’t know if they’ll like merino socks and doesn’t want to drop $20+. With that being said I like them a lot and will buy more and try different brands.
Thin socks
Thin socks and has static shock wearing around the house with just the socks on. I guess good for minimal travel since it will probably dry quick after washing.
Comfortable
Fit well, very comfortable. I really like the crew length size.
