Worried about airline overweight luggage fees? This bag from Ricardo Beverly Hills weighs itself with a built-in digital scale. The case's nylon exterior is treated with Nano-Tex, which uses nano-sized molecules that attach to the fabric's fibers to protect the nylon against stains and moisture. Richard Ricardo Gibbs, who spent almost 50 years selling travel products, founded the La Mirada, Calif., luggage manufacturer 30 years ago. Led today by Robert Dodson, the company sells its collections in Macy's and specialty travel-goods shops.
