I am on the Steinmeister tour departing London on Sept 15th and to be honest I have no idea how I am bringing along a sleeping bag. What is the best thing to do? Bring a backpack, or shove one into a suitcase? I will be traveling before the tour and will not need the sleeping bag so I also thought about purchasing one once I’m in London? Hopefully someone has some advise or can tell me what they plan on doing. Thanks!
