Very good quality, great fit. Expensive, but worth it...

Jeff KFebruary 10, 2022✓ Verified purchase

This baselayer top is awesome, is very warm, and comfortable to wear all day. It's long so it easily tucks in and stays that way. Or, if you don't tuck it in, the long waist hugs your hips and keeps the wind from blowing up into your open coat. This keeps you very warm, but is breathable enough to wear in the house all day. Wearing this in the house allows me to keep my heat much lower saving me $$$ on my utility bill. So while this is expensive, it has lasted and is great quality. I bought a 2nd one because I wear mine so often now I hate being without when I have to wash the one. Btw, I wear this over a cotton shirt, which allows me to wear it multiple days without needing to wash it more frequently. I think this too will make the life be extended. Definitely recommend. It's worth the cost. Also, the price on this in Oct 2021 was $20 cheaper than the 2nd one I bought in January. Not sure if that's a result of the inflation we're seeing now or because it's "in season" and naturally higher cost. I'm going to keep an eye on them and see if the cost drops in July when they are less likely to be selling. Read more

Nice mid layer

SeedroJanuary 13, 2026✓ Verified purchase

Great looking shirt! Can be worn as a single base layer or mid layer with a light wool layer beneath it. Warm and comfortable. Can be purchased elsewhere for much less. After buying it here, I felt a bit ripped off. Read more

Awesome warm top

This is a great sweater, thin enough to wear as an undershirt in cold weather. It’s a bit expensive but worth the money, and a lot better than my similar synthetics. Read more

Always something....

David DorneyFebruary 12, 2026✓ Verified purchase

Nice shirt but not the color I ordered. Ordered Mink Heather, got Charcoal. Not worth the hassle to return it for the correct one. Heavier weight than merino tech tops but not as form fitting and much higher price. Read more

High quality and fast shipping

Kevin StangerJanuary 10, 2026✓ Verified purchase

I’m all about, comfort, function and quality. Used to buy these from REI, took two weeks to arrive and a poor selection of sizes and colors. No more! Took two days. Fantastic product for outdoor enthusiasts looking for quality layering. Read more

the Best merino

VDMJanuary 31, 2025✓ Verified purchase

This is the softest, thinnest and easiest wool to wear even directly against the skin. If worn as part of several layers it’s very warm while incredibly not bulky. Medium fine for me at 5’8” 170, could have fit into a small, but I layer it so the med is good in that regard Read more
