Men's Alpaca Wool Base Layer: 300 Lightweight Half-Zip

Beautiful garment. Loved the fit (L). Well tailored and warm. Missing a star as I found it itchy against the skin. Not too much of n issue for me, as I don't wear as a base layer, but would find it uncomfortable if I did. If Arms of Andes addresses this one concern, I'll happily order another-

Great quality, soft and odorless

It's quickly become my favorite piece of clothing. Even wearing this without an additional layer has proven quite effective in some of the warmer winter days, but as a base layer it's been a really effective workhorse. Great quality, very soft, and as best I can tell all that's advertised about odor resistance is definitely true.

Important (?) Note: The first time I wore this it felt fairly itchy. They advertise as itch free so I was concerned, as I've heard some people have bad reactions to 100% wool. However, it seems it was just a "new garment" problem. After wearing it out on a run, whatever itch I felt went away completely and now only the softness remains. I haven't read anyone else mention anything like it, but if you've never worn 100% wool before I figured I'd share my experience with it. I'm really glad I forced myself to give it a try.

luxurious

This is a handsome, warm, and luxurious top. Besides the expected property of alpaca, I am impressed with how comfortable and lush the top feels. The neck is a close fit, no gaps - at least for my neck size - which makes it comfortable and warm. Although not recommended by Arms of Andes, I laundered mine in warm water and tumble dry low. - no problem. no shrinkage, no bleeding of color. Laundered twice so far and it fits and feels the same as new.

Great, but not quite what I expected

This is a gorgeous and comfortable garment! Wore it basically 4 strait days traveling with a little light hiking mixed in; worked great in all situations. Based on my experience with AoA t-shirts and other alpaca brands, I was expecting this to be a lightweight layer, but this sucker is relatively heavy! Clearly a denser and finer weave than other alpaca products. To be clear- I love it and will wear it often, but it is not a lightweight 'just in case' layer. As with all alpaca and merinos, it breathes well, stretches nicely and works in a range of temps. Also should note that the fit of all AoA garments is very, very athletic. This one more so even than the Ts. In most outdoor brands I am a gently snug large or loose XL. In this the 2XL is still snug around the midsection and very long (as expected with this large of a size). Also worth noting that the fabric is very streamlined yet soft out of the box, but I did start to notice some tiny pilling in many places right away. Still looks and feels great. Loves it so much I went back and bought the )even heavier 420) full zip jacket!
