Men's Merino Base Layer

This is a well-fitting merino wool base layer, cut to enable maximum movement for the upper body/arms, without the top riding up. If you size it correctly, it should feel snug, but not tight. Critically, there are no seams directly under the armpit, joining the sleeve to the body. With some base layers this can chafe or ride into the arm pit and be uncomfortable. Instead, there is a diamond shaped piece that has seams running around outside of this area and this makes the top much more wearable.
The fabric is thin, but also soft against the skin, and without the slightly abrasive feel other merino tops can have. This means there is a feeling of loft and warmth. This is important for 2 main reasons: 1 – it is warm and great for layering and, 2 - most people tend to sleep in their base layers on treks so you want one that you could happily sleep in.
The fit is slightly tighter that I expected. I am about 5’8” and broad shouldered. I own a medium Hemming Mid layer fleece, which fits well, but had to move to a large for this garment to get a great fit.
Overall, a simple, comfortable top, which is executed well and is perfect for just about any outdoors activity (or just simply wearing at home).

100% yes. What a great product.

Good fit and quality mwrion base layer.
