my second Merino 250g half zipper thermal top.
I loved my first one that I used for almost 60-day in France and Spain that I wanted a second one. That thermal top with MP t-shirt and vest were all I needed for very cool spring mornings during the trip. The quality is beyond comparison the my other well-known outdoor clothes. I highly recommend MP products. I now have several t-shirts, socks, thermal tops and a bottom.

Essential to my travel wear
Love this piece. I have a couple in different colors. Pack one for my journey everytime. Works as a stand alone, layered piece. Easy care and replaced other pieces of clothing I used to pack
