Perfect merino base layer
10 months ago
Extra comfy and warm merino base layer! The waist band is nice and holds the pants in place. The ankles have a seam so they are tight fitting. Really comfortable and run pretty true to size. I’m 5’6, 135 lbs and have a medium. Recommended!

Great as pajamas!

Purchased the top and bottoms and LOVE them. Use them as pajamas and they're great for travel and multiple wears without getting stinky.
