Review: Finally a "Tall" that stays tucked! Soft, warm, and perfect for active days - The Fit & Length: As someone who usually struggles with shirts riding up, I am thrilled with the Tall version of this base layer. The length is fantastic—it stays securely tucked in even after a full day of bending, moving, and outdoor activity. Unlike other "tall" brands that just get wider, this one actually provides the vertical coverage needed for a 6ft+ frame. Even after several wash cycles. Comfort & Warmth: Material Quality: The Merino wool is incredibly soft and comfortable against the skin. There’s zero "itch factor," which can be a concern with wool. It provides a very consistent layer of warmth without making me feel like I'm overheating. The Snug Factor: I will note that the fit is a bit more snug than I usually prefer in a standard shirt. However, for a base layer, this is actually a benefit. It isn't uncomfortably tight, and the close fit is much better for layering and heat retention than something too loose. Final Verdict: 5 Stars. It’s rare to find a Merino piece that gets the "Tall" sizing right while maintaining this level of comfort. If you need a reliable, stay-put base layer for cold weather, this is the one.
Review: The perfect wool thin base layer - THAT'S WARM! - My husband is allergic to lots of fibers - he really only likes 100% cotton and wool and thankfully they don't irritate his skin. He LOVES this base layer - it's super warm, super SOFT, and very durable. I like how thin it is, while also providing a good warm layer. He immediately wanted to see if there was other colors offered. It was SO MUCH cheaper than some of the other online brands. Super happy with this purchase for him.

## 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

### ⭐⭐⭐⭐⭐ Great base layer
*by D***N on May 18, 2025*

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.
