At least this one thing is still 100% wool
Recently purchased a 4th, 250ZipT. LUV them!! My first one is 9 years old, and gets worn constantly, with no signs of wear. Washes great, and doesn't need to be washed often as it never smells bad. But I'd like to comment that I'm disappointed in the Smartwool company overall, because all other ...

Used to love this garment
I have purchased one of these tnecks each of the last 6 years. They keep getting smaller and smaller. The one I bought this year is likely my last since it barely accommodates me. Good thing that they are high quality since the 6 I have will likely last a very long time. This is my go to base...

I own several of these 1/4 zips in different colors. This time I bought the Pool Blue Joviansphere. It's so vibrant and beautiful. I also have the matching merino base layer crew neck in this style and I love it. Now I can double-down on this awesome style by wearing the 1/4 zip on top of the matching crew neck. The fabric is so comfortable to wear: soft and non-itchy. It's warm but somehow also breathable, and it doesn't hold any odor. Highly recommend!!
need like 5 more!

I took this thermal on a 3-week trip to Patagonia. I wore it almost every day: hiking, paddling, including to bed at night! It was soft, warm, and never developed a bad smell! It hasn't pilled like some wool sweaters, and I think it will last forever LOL. I LOVE IT!
I would buy the merino 1/4 zip base layers to get new design

This is my third thermal Metino base layer. Sometimes I wear not a wool layer underneath. I wear them hiking in winter and mostly skiing. They all keep me so comfortably warm. I don't wash them after each use, usually just air overnight. No itching, no shrinking after wash
They should add some wearable colors!

I would buy them again and wear them everyday, if there were some wearable colors that would go with everyday clothing! White, cream, nice pastels, light grey, fresh nice colors!
The best base layer I've ever owned!

This base layer is buttery soft, warm, and incredibly breathable. It's perfect to spend your entire day in - both whatever outdoor activities you're doing and the subsequent lounging. I also love the snowflake pattern! I will always buy Smartwool base layers.
Great fit and weight

I thoroughly enjoy the 1/4 zip base layers myself and own many, and this was a gift for my sister. She too is very happy with it, especially as these polar vertex weather fronts continue to push down into the US!
I would buy all the time. Love all their products
