Start out right with the Black Crows Chevron Merino Blend Men's Long Sleeve, with 87% merino wool for warmth and 13% polyamide for greater strength, durability, and breathability. This one as opposed to a plain baselayer for its functionality as a casual après ski tee as well as your go-to start to the day. The right weight, neatly splitting the 100 grs which is too thin and the 200 grs which is too thick, coming in at 155 grs… giving you the perfect drape and opacity and just the right balance between warmth and wicking breathability. Naturally odor repellent too so you can come off the trek and still be reasonably presentable.
