It's better to prepare sooner than later, so grab a Flight 001 Spacepak Set now before everyone else discovers how fantastically functional these are! You get three pieces for your carry on bag: a Spacepak Clothes bag, a Spacepak Shoe bag, and a Spacepak Mini Toiletry bag. With the Spacepak Clothes bag, you get one side of the bag for clean clothes and the other for dirty clothes. The Spacepak Shoe bag is large enough for a pair of hard shoes (like sneakers) and a pair of soft shoes (like flats or flip flops). And a Spacepak Mini Toiletry bag provides storage with a mesh zip pocket. Stash, well, pretty much everything with this Spacepak Set!
