Great base layer for colder weather activities

I purchased the 160 ultralight after having experienced the benefits of alpaca socks. First use on a chilly kayak paddle with a sweatshirt on top. I did notice a little itching but not enough to be very uncomfortable. As sun came out nd I warmed up, i shed the outer shirt but never felt sweaty with this shirt wicking moisture very effectively. 2nd use I wore it on a bike ride in moderate temperature with light shirt on top to reduce wind chill. Worked great and again felt dry whole time even though I was perspiring. I am sold on performance and no odors. If they were less expensive I would certainly purchase a few more shirts.

Hi! Thank you so much for sharing your experience! It’s great to hear how well your 160 ultralight has performed, from chilly kayak paddles to bike rides. Alpaca is such a unique material, keeping you comfortable and dry while wicking away moisture, and the natural odor resistance is definitely a bonus! We understand the cost can be a consideration, but we're thrilled you find the performance worth it. Thanks again for your feedback, and we hope you enjoy many more adventures in your shirt!

Alpaca Itch

I received an Ultralight 160 long sleeved shirt 3 weeks ago. I’ve worn it for short periods of time around the house on 3 occasions.
The construction and fit are excellent.
Unfortunately, every time I put it on, I experience significant itching within a short period of time and I’m concluding that I won’t be able to wear the shirt.

I wish that I had paid more attention to the 15 day return policy!

Hi Ned!

Thank you for reaching out and sharing your experience with the Ultralight 160 long-sleeved shirt. I'm sorry to hear about the itching issue you've encountered. Even though our return policy is 15 days, we want you to be satisfied with your purchase.

Here are a few solutions that might help with the itching:

1. **Washing the Shirt:** Sometimes, washing the shirt a couple of times with a gentle detergent can help soften the fibers and reduce itching.

2. **Wearing a Base Layer:** You could try wearing a lightweight, breathable base layer underneath the shirt to create a barrier between your skin and the fabric.

3. **Fabric Softener:** Using a gentle fabric softener can also help make the fabric more comfortable against your skin.

We understand how frustrating this can be, and we’re here to help find a solution that works for you. If you continue to have issues, please let us know, and we can discuss further options.

Thank you for your understanding and for giving our product a try!

Ultralight 160 shirt

I love this shirt! I was looking for a sun protection shirt but really wanted to stay away from synthetic fibers. I appreciate that this is 100% alpaca. When I first tried it on it felt a bit scratchy but not much more than sheep’s wool. After the first wear though it became super soft and comfortable. I use it for summer running and it wicked sweat surprisingly well on top of keeping my body temp nice and cool in the humid New England Summers

Thank you for sharing your experience with our alpaca shirt! We're glad to hear that it has exceeded your expectations for sun protection and comfort. It's wonderful that the initial scratchiness softened after the first wear, making it perfect for your summer runs. Your feedback on its breathability and moisture-wicking properties is greatly appreciated. Enjoy your runs, and thank you for choosing our product!

Style, warmth, well made ... everything one wants in a modern day wool shirt

The prairie winds and long(ish) winters where I live (western Canada) makes wool clothing a near must. After pretty much ditching cotton, I practically live in wool (merino mainly). As such, I'm always on the lookout for new clothing and when I chanced upon Arms of Andes selling shirts during a little jaunt on the internet, it piqued my interest and I had to give it a try. I've not had the chance to wear it in the coldest of winter days as we've had a relatively mild winter, so I'll withhold my judgement on it's ability to keep me warm(er) than merino - although in truth it's held out fine and toasty in some -5C to -10C weather, so I suspect it would make a great base layer. Mainly, I have been wearing it a lot just as a casual shirt around the house and for some casual social outings and my opinion? Simple a fantastic shirt. But first, the 'bad'. Yes, there is a bit of a mild itchiness which would maybe seem more pronounced if you are new to wool, but for me, it's minor. I think I've just gotten use to it so it doesn't bother me and after multiple wears, it just becomes less and less noticeable. It's probably the only point that might give pause when deciding whether to purchase. But beyond that. The shirt is simply well made and looks fantastic. Color is great. The cut. Couple that with the fact that this will keep one toasty during cooler days, and my decision to recommend this shirt is a no brainer. Even the point that I'm not purchasing from a big box store and that this company seems legitimate when it comes to their 'raison d'etre' - only adds to the appeal. I'm a huge fan of wool and this is my first foray into the world of alpaca clothing (except for an alpaca beanie - which true to the claims I find is warmer than it's merino wool cousin). Sizing is always hit and miss with me when ordering from the internet, and especially clothing from out of country, but the size guide was fine. As stated, the style is more 'slim' (which I simply can't pull off with the dad bode - well, almost) and so I decided to size up as suggested and the shirt wears fine. Now that I got the sizing dialed in, only thing left is for me to save up for my next order - which will happen. And you? I wavered long enough for the both of us. Just make the purchase already!

Really comfy shirt

I recently gained interest with wool and wanted a nice quality alpaca wool shirt. I initially thought it mildly irritated my skin but after a wear or two it became one of my softest, favorite shirts. I am 5-8 180 and I can wear medium with some shirts but I had to get a large. I bought a second shirt as well. I strongly recommend!

Thank you so much for preference and lovely comment :D
