I like Tourmaline color better as I think this color is easily to match clothing. However, I already have 2 black bags already. As cadet is in blue shade and considering its in lighter shade, wear and tear will be more obvious but the color look nice as well. I have not see before these 2 colors in real but on hgbagsonline site. They are running a promotion code now so can get further discount I am gathering opinions here before I decide. Please help to input your thought? Thanks!
