Much smaller than expected. [SEP] It is considerably smaller than what I would have expected, (In all fairness, I should have looked at the dimensions more carefully)<br />It is a glorified ziplock bag with a zipper.<br />I may be getting a little ahead of myself: but I do not have a lot of confidence in the quality of this product.<br /><br />On the positive: It is light and clear.<br /><br />I will be updating my review after taking a trip - or two with it.
