In such a competitive market of great Merino options, the Rab MeCo 250 struck me as one of the best we tested. From the softness of the wool blended with Cocona, to the high snug collar and the smaller thumb slots in the sleeves that offered extra palm protection, so many of the features were spot on.

Wicking
The chest zipper length is one of the longest in the test group allowing for better ventilation if needed. But the best benefits are found in the wicking performance, where Cocona blended with Merino seemed to enhance dry times and moisture spread in our lab tests. The only aspect I felt missing was when I found myself wearing this as my only layer on warm to cool days, when a zipped pocket would have added to its swankiness.

Performance  
The midweight layer seemed to have just the right amount of thickness to be worn as a midlayer on very cold days, or as a baselayer in cool to warm conditions. Its longer length also prevented it from sliding up on frame during sports that required extension.
