Love this top. I have the Ebony Marle Heather. Works great and quite light. I've worn it hiking Mt Whitney, climbing, and to work. Goes relly well with jeans or a scirt. I get a ton of complements every time I wear it. Breathes really well. Wool really has the best performance. Great for layering. I love that I can wear it out or while doing some serious activity. I want a second one!
