I bought this top for me because I always like how they look on my husband. He has many but I don't think any are the all-season merino blend like this one. I bought one last year and knew from experience how wonderful this material is year-round. I just throw it into my backpack or tote and keep it there because I like to be able to pull it out especially in the warm weather when everyone and everywhere air conditioners are running, even in the car. It doesn't take up a lot of room and does not weigh too much. It has saved me so many times, not to mention how many times I've saved my husband and friends! This year I bought two more different colors, and this brand is even better looking, the collar stands out, really pops!
This is a stylish, thin, high quality merino wool base layer that can double over a t shirt to take the chill out of a summer evening. It is highly permeable so good for workouts and under other layers when is get colder.
Nice looking, great color, lightweight, comfortable
Great base layer that somehow manages to keep you warm when needed but breathable enough that you don’t get hot. For me it’s perfect by itself on those mid-40s to low-50s days. Perfect for layering, too, when it’s colder. Does a great job of wicking. Should last a long time. Definitely worth the investment.
