I've gained weight this year so my beloved Ibex tops don't fit. I was so happy to find your merino in larger sizes--this is a niche that most performance clothing makers ignore completely. I ordered the Layla in 1X, which is the size I usually wear from other clothing lines. It's plenty ample, the arms and the body are long. The next size down might have worked but I liked how the 1X didn't cling to my midsection. The shirt does not smell, even after wearing for several days. We are up north and it's kind of chilly so I was able to layer my two Laylas together for added warmth and that worked great. Now I need a hoodie or a jacket or both!
