I wound up wearing this every day of a multi-day hike in the Carpathian Mountains in Romania. I had brought other base layers but this one was so fantastic I didn’t want to wear anything else. I’m 6’2” and 160 and got a size M. There’s plenty of length in the sleeves for me and it has long tails. It’s soft, comfortable, super durable, and it dries extremely fast. I would rinse it in the sink after a hike and it was ready by morning for the next day, fresh as a daisy, no smells. It’s the best 100% merino hoodie I’ve ever worn. I’m now a customer for life.
