The ActiVest is a useful vest -- well-made, lots of pockets, rain hood, warm -- that integrates the design of the Slouch!Buster travel chair (the straps fold into their own pockets when not in use). My wife got this for me last Xmas, and I have found it very useful on dozens of occasions: beach walks, hikes, meditation groups, and other situations where I need back support. When I was younger my back needed no support, but luckily this was invented just as I felt the need for it. Nice to be part of a large, inventive, geriatric generation.
