How soon on the market?
Given that I have to carry all the luggage on holidays, a set of these would be brill. Also would transofrm my hiking and camping! I demand these now!
In addition, how cool for the frail, elderly, etc., who can barely carry two tins of cat food (= supper).
Not as totally brilliant as would be the full Starship Trooper armour (from the book, not the film), but i will take it for a starter.
