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.

The 300 gsm half zip base layer worked perfectly in the Canadian mountains. It stayed warm, didn't get heavy with sweat, and dried out odor free overnight ready for the next day. Time will tell how it holds up, but my other Arms of Andes pieces have all proven durable enough, so I have no reason to expect this will be any different. Great stuff!
Hi Derick! Thank you so much for sharing your experience! We’re glad to hear the 300 gsm half zip base layer performed well in the Canadian mountains. It’s great to know it was ready for the next day, too. We truly appreciate your support and feedback!

Very warm and it fits well

The actual alpaca material is very soft and warm. The thread used to stitch it together is very scratchy even after washing. I can’t wear it against my skin.

Bought for my son for Christmas. It was a huge hit, base later that looks nice off the slopes!

Really great shirt. Not itchy at all and seems to temperature regulate. Also classy enough to wear around town as a regular shirt. Highly recommended!
