When traveling I like to carry as small a purse as I can.  However, since I recently acquired large fashion sunglasses, this has been difficult.  With this product, I can zip my sunglasses into the case and clip the cast to my small purse - problem solved! I do wish someone would make a case of this type with a more femine design.  This case is very sporty as the name suggests, but I would like to have one in a softer fabric, in a femine color or print.
