Being a daily slackliner, it helps to have a bag that is ready to go that I can just grab and take to the park. My buddy who also slacklines quite often came up with a name for this: The ESK (emergency slackline kit). I thought it was very fitting as there are definitely emergencies when a slackline setup would have saved the day. I have assembled my own ESK that I think is pretty good for my style of slacklining.
