Great products

Purchased the warmest alpaca top mainly for sitting at winter football matches ( directly facing cold winds from the North Sea).

Very pleased with the warmth, quality and style. The length is also excellent for keeping the midriff warm and tucking securely in trousers.

I am wearing it most of the time. A plaudit on its own.

The company are small, ethical, reliable and look after their customers.

The overall costs to the UK are higher than local options. However, I still selected Arms of Andes. I have reordered a number of their products.

Hi Richard! Thank you so much for your kind words and continued support! We're thrilled to hear that the alpaca top is keeping you warm at those chilly football matches and to know you're pleased with the quality, style, and fit. We’re also very happy to hear you’re enjoying it so much you wear it most of the time, that’s definitely a plaudit in itself!

We truly appreciate your support of our company, and we’re always here to look after our customers. We're honored that you chose Arms of Andes and continue to reorder from us. Thank you again!

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.
