Like all Mammut products I bought over the years, this one is truly excellent, and I am very glad that CampSaver carries this brand. The Go Dry Longsleeve is a wonderful light, thin, base layer, that actually keeps one dry (unlike other brands that claim they do, but don't...) I use mine as a base layer for outdoor activities in cold weather, and found that it also works beautifully as a gym shirt by itself for people who sweat a lot, like myself. A great product!
