Are you a compulsive packer? Do you hate wrinkled clothes? Then get one of these. Your shirts will still have creases, but no wrinkles. That makes them easier to iron in the hotel. The handy plastic sheet does a fair job at being a folding guide, but don't think it's a breeze to use--you still have to be very careful when folding clothes. Weight is a non-issue. You also have to be careful about the velcro fasteners. Don't let them touch delicate fabrics or you'll be sorry. That's the reason for -1 star.
