This baselayer is the perfect weight for a wide range of activities. I wore it mostly for ski touring and resort skiing and found that the material breathes well while providing good warmth under variable conditions. I will definitely continue to wear it for spring and fall activities. Merino FTW! I found the fit true to size.

So cozy
I bought the Stardust color one and I know it will become a favorite wardrobe staple in no time. The material is warm yet breathable, and noticeably high quality. I love that it is also a balaclava and it’s got a pony tail holder

Pretty pattern, soft wool
Material is soft, not scratchy. The color & pattern ("fresh mint floral") are really cool - the light blue background is a little darker in person than the photos which I like. This is a thin weight wool - nice as a base layer or alone on a mild day.

Great all-around base layer
This is a great baselayer. I wear it while winter backpacking in the desert. It is nice and long in the torso and sleeves, which works well for my 5'10" frame. The material is breathable and quick to dry. For my purposes, the hood is not terribly useful as it is tight, more of a balaclava, but I do enjoy the extra material at the neck for keeping warm. I also enjoy the pattern, it's a nice break from the ubiquitous solid-color base layers.

Best. Base layer. Ever.
These are by far the best base layers a girl could ask for! Very warm but breathable.
