James L.wrote a review of De Marchi Merino Base Layer - Men's on September 14, 2017
Familiarity: I've used it several times
I own a number of De Marchi items, including jerseys and base layers. I have always taken a large size for De Marchi tops, so it made sense that I order the same for this merino base layer. When it arrived I tried it on and it fit just as my other D M kit does. As with all of my cycling clothing, I washed it on the gentle cycle in medium temp water. No dryer as usual; I line dry everything, since the items last longer. After this base layer dried I put it on and found that it had shrunk so much that it looked like a ridiculous midriff shirt from the 1970s. Fortunately some of my bib shorts are cut high enough to keep this base layer in place—but only barely, pun intended.
Incidentally, I'm quite familiar with wool cycling kit. When I was a young racer, wool jerseys were all that was available. Even today I lean towards the so-called retro style wool (blend) jerseys such as De Marchis. Hot washing temps and dryers are out of the question.
The lesson I learned from this purchase is that it doesn't fit properly until after the first washing. Count me disappointed.
