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.

100% Natural and Absolutely Wonderful!

100% natural fabrics are hard to come by. Most brands combine natural materials with stuff like Polyester, which defeats the purpose.

This is 100% Alpaca and amazing - no chemicals added, with natural or low-impact dyes.

Loved the long-sleeve

I wrote this to the Sacred Valley, Cusco, Machu Picchu. It was very soft and did a great job keeping me cool, and also keeping me warm. The temperature regulation on this shirt is really good. The fit also looks nice, I felt like it looked better on me than a typical wool or cotton long-sleeve shirt.

Everyday go to

As a base layer in winter or stand alone in spring or fall this is something I always have on. Super lightweight and comfortable and out performs synthetics in the active department because of the breathability ditch the plastics try one of these

Ultralight and super warm

I found this garment to be very lightweight but yet very warm. Cool conditions. When it was warm outdoors it breathes very well and doesn't over heat you

Itchy

I was hoping for less itchy. Sort of defeats the purpose if I have wear a cotton tee underneath.
