...is light enough to carry easily when travelling, but is there one that folds up to half the usual length if you see what I mean? I need to fly, then go on a train, then a tube with ds wh is just 3, so hefting a full length umbrella folding thing isn't really an option. Do they go smaller? When it's in use it doesn't need to have bells and whistles, just a frame and a basic seat will do.
Anyone know?!
