I now have 3 of the Short Fin long sleeve linen shirts: aqua, sand, and peach.  The aqua is the first and it is the blend; fits great but a bit warmer in the north Georgia climate then I thought it would be.  Just received the other two, 1 is 100% linen and other is blended even though I thought both were 100% linen.  And (HERE IS THE IMPORTANT PART) they have a different cut from the first shirt.  Just a tad tighter in the torso but much tighter thru the biceps.
