An item I've been wearing since October all the way into February, this is a super layering piece for winter running, fall rides and trail runs, and even just a regular athleisure staple. The merino keeps heat in while also keeping moisture out. Great sizing and true to size - I do wish it was a little less long though (am 5'5) and it comes down far past my hips.
I absolutely love this piece - I use it for mountain biking in the Spring & Fall, as well as for touring and running in winter. Super breathable and light, yet keeps you nice and warm. Definitely a sports-wardrobe staple!
