I have a GT260 sweater and jacket, both in medium. The jacket fits perfectly, but the sweater is a little small.
I decided to size up to large on this in case it ran small as well or I could layer with easily if it didn't.
160, 5'11", 36ish chest.
Otherwise it's as described! Nice and warm and much thicker than the 260 weight jacket I have.
