Care for your layer

Hand wash or machine wash on a gentle/wool cycle in cold water (50-68°F). Use a mild wool-safe or pH-neutral detergent. Wash with similar colors. Don't bleach or use fabric softener.

Reshape while damp and lay flat to dry. Don't tumble dry, twist, or wring. Cool iron if needed. Store folded in a cool, dry space with airflow; avoid hanging.

Naturally dyed colors can transfer with sweat or friction. Wear them with dark clothing or equipment, wash sparingly, and avoid citric acid, which can lighten the color.

Very slim cut

I haven’t worn it yet so I can’t compare it to merino wool but the fit is Extremely fitted. I had to size up 2 sizes which then made the length very long

Itchy

Itchy and runs small. Not soft

Hi there! Thanks for sharing your feedback. We're always working to improve both our products and service, so input like yours is invaluable.

Regarding softness and itchiness: alpaca wool is naturally soft and hypoallergenic for most, but we understand that individual sensitivity can vary. Regarding sizing: our garments are designed with a slim/functional fit, so sizing up is always a great option if you prefer a more relaxed feel. Both our size guide and fabric care information are available on the product page.

That said, we'll absolutely take your comments into consideration as we continue to evolve our offerings, comfort and sustainability should always go hand in hand. We hope we have a chance to serve you better in the future!

Love the shirt but doesn’t last long.

Washing makes it look quite worn. For the price the material Should hold up better.

Second purchase

After buying two short sleeve V-neck ultra-lightweight tees I decided I needed a long sleeve one for cooler days, for under my flannel shirts. Arms of Andes are well made, comfortable and a perfect base layer for cooler temps. Being an older adult, I appreciate the comfort and temp regulating properties of the alpaca wool fabric.

Hi Karen, thank you so much for your continued support, we’re truly grateful you came back for another piece. It’s wonderful to hear that you’re enjoying the comfort and temperature-regulating qualities of the alpaca fiber. We really appreciate you sharing your experience!
