Warm!

I use this hiking/backpacking along with an alpaca hoodie. My jacket is an Outdoor Vitals Down Jacket. To backpack, I've found that just using this zip-up is all you need and store the hoodie. Also, I have pit zips on my jacket and must open them. This zip-up is super warm when sitting around the campsite in winter, 20 degrees when layered with a hoodie and jacket. It does have a little bit of a wool itch feel, but after wearing it more, it seems to subside. I also appreciate it zipping further down so you can regulate your temperature.

I’m breaking up with cotton

Alpaca is my new fabric of choice. Love the base layer and thank you for sending it along so quickly. I also love your mission and commitment supporting both the environment and people of Peru. Please consider adding three back pockets to the base layer to create a cycling jersey.

Hi Chris, Thank you for such a thoughtful and enthusiastic review! We’re thrilled to hear that alpaca has won you over and that you’re loving your base layer. It’s wonderful to know you appreciate our mission and commitment to supporting the environment and the people of Peru, it truly means a lot to us.

Your idea of adding three back pockets to create a cycling jersey is fantastic! We’ll definitely pass your suggestion along to our product development team for consideration.

If you have any other ideas or need assistance, don’t hesitate to reach out. We’re here to help and look forward to serving you again!

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-
