Seems to run a bit small. I like my sun hoodies to be loose fitting because they keep me much cooler that way. I usually buy men's cuts because women's cuts are typically tight and too form fitting. I usually wear medium to large sizes. I bought this women's version in an XL but it's still tight on upper arms and across my shoulders and chest. I ordered another in XXL (even my coats and outer layers are only XL at most) and we shall see how it fits once it arrives. Otherwise the quality of the shirt seems great. I wish hunting companies would figure out that women like me are not trying to be sexy while we work/hunt and we want comfortable and practical clothing options that we can move in.
