my  Coleman Cable 08862 25-foot Ultra-Heavy-Duty Truck and Auto Battery Booster Cables , 2-gauge  I 'll admit it , it be a snug fit and you have to roll up you cable nice and neat to get they to fit and there be not much room leave over . there be zero room leave over with large jumper cable in the bag . the only thing I have in there be the jumper cable and a laminated large print 8.5 x11 instruction sheet on how to use they . that say , if you can get my 25 foot , 2gauge jumper cable into this bag , you can probably fit almost any other set of jumper cable into this bag . the bag be well construct , with nice zipper and good sturdy handle . it really make lug around jumper cable a tidy affair . I highly recommend you have a bag like this for you jumper cable , particularly if you cable be large for a variety of reason : a -rrb- keep they neat b -rrb- make more room for other stuff c -rrb- keep the insulation of cable from get rough up d -rrb- one tidy package if you need to grab it and walk I can not find many con to this bag . it be nice and the price be right too !
