Review: Great base layer - Top notch base layer. Super comfortable, soft and warm. I've worn mine for the past year-ish, and the quality is very good, washing it does not shrink it, color is still good and it fits me really well. I am 6'4", 235 lbs, 36" sleeve, and I bought XL big and tall. Recommended.
Review: Meriwool very nice! - Purchased long sleeve thermal Base layer in medium of 250 weight. 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.

## Questions & Answers

**Q: What is the manufacturing country for this product?**
A: My label says China  :(

**Q: What percentage of wool are these items**
A: In spite the retailer claim, it is not 100% merino wool. 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
