this be the second of these bag that I have have . the first I buy over 15 year ago at a Wal-Mart before they all become Super Wal-Mart . it do its job for a long time and finally the zipper give up . I hunt for another one and could not find one anywhere locally so I order one from Amazon . First of all I 'll point out that I have no use for the outer pocket . while I agree with other reviewer that it be very small and not very useful , it be a non-issue for this review . it would be fine with I if it be not there at all . the set of jumper cable I have be heavy duty and 20 foot long . I lay they out and verify the length with a tape measure and they be in fact 20 foot long . they roll up and fit into the bag nicely . I do not know why so many people say they heavy cable will not fit in it , or they long cable wont fit in it . my cable be heavy and long and they fit in it just right . the only noticeable difference I see between this bag and the one I have originally be that this one be make of a rip-stop material . my original one be just make of regular canvas , so I would say this be a upgrade . overall I be very happy with the bag , and if you have a set of jumper cable that you want to stow in a bag then I recommend you give this one a try .
