Smartwool on Sale: Merino 150 Base Layer Top
On top of being great for keeping you cool on hot days and being a warm bottom layer for cooler temps, the Merino 150 Base Layer is also quite durable. The brand makes it with 87% merino wool wrapped around a nylon core for durability.
And the plant-based dye used in select colors of this shirt is just one example of Smartwool’s sustainable practices. It’s designed with a longer fit, which is great for taller people and those looking for more coverage. And the raglan sleeve design adds comfort when layered.
