Got my new Luggageworks Aurora today. Pretty nice bag... feel like I need an engineering degree to figure out what all the pockets are for ! haha in seriousness though - what do ya'll pack out for a 4 day (that will probably end up being 6 days...) I was hoping to hang my back pack off the J hook and put gym clothes in the back pack but the backpack may be a little long. do all the LW have the internal panels/pockets/compartments ? might trade mine in for a simpler model lol !
