From the skin out, start with the Black Crows Chevron Merino Blend Women’s Long Sleeve, featuring an 87% merino wool for warmth and 13% polyamide for greater strength and durability blend. Breathable, naturally odor resisting, quick dry, and a fabric that insulates even when damp this is the way to start your layering system. The right weight this neatly splits the 100 grs which is too thin and the 200 grs which is too thick, coming in at 155 grs… giving you the perfect weight along with a comfortable drape and the opacity you want so you can wear this as your casual après ski tee. The first layer built to keep you comfortable in the cold.
