After one month, it is holding up very well. Have machine washed it in cold, and hung dry and it has kept its size. It is soft and warm. A healthy, breathable fiber worth every penny. The waist is done of very high quality, wide and not scrunched, rather a fine hold within the material. Our only wish is that they came in v-neck too. Review: My husband loves it - My husband really loves this mid-layer. He's climbing 14-ers and he starts as the earliest rays of dawn light the path. This merino wool mid layer is perfect for him when the high altitude mornings are cold but quickly warm with the sun and his exertion. He also loves that it stays in place when his pack rubs and causes other shirts to ride up. The prices is much better than all of the local chain sporting goods stores. We'll probably be buying more in other colors. ## Features - PACKAGE INCLUDES: 1 – Merino Wool Men’s Merino Wool Thermal Crewneck Top in Black / Medium | MATERIAL: 18.5 Micron, 100% Merino wool, 250g/m2 | FIT: Fitted - SUPER SOFT: 100% all natural superfine 18.5-micron Merino wool ensures comfort all day – no itch!

I arranged a burn test and a microscopy: the shirt made of merino wool + cotton fibers (in lesser degree). I'd bet 95% merino + 5% cotton. All materials give "natural" sources in burn test. **Q: What is the sleeve length in inches for L and XL?** A: I don't have the large but the extra large sleeve length from the outside shoulder seem to the cuff is 25 inches and the inside seem from the armpit to the cuff is 21 inches. **Q: Where is this product made?** A: China ## Customer Reviews ### ⭐⭐⭐⭐⭐ Meriwool very nice! *by A***Q on November 18, 2024* Purchased long sleeve thermal Base layer in medium of 250 weight.
