I ordered two, a "his and hers" set of the Sigma 3, 22 inch expandable vertical carry-on luggage cases. I am pleased with the price and quality of the luggage. The luggage held-up on four planes without a single rip or tear on a recent trip from SC to NY, and back. The luggage has 2 easy-access external pockets, an internal mesh lid pocket, and elastic tie-down straps to keep packed items secure. The luggage also has a attach-mate strap for ease in carrying. The luggage is light-weight (7.4 lbs), and has a sturdy frame. The wheel housings are mounted at the outside corners of the cases, and as advertised, afforded smooth operations over a variety of surfaces inc. parking lots, runways, and airport terminals. The luggage has a lock-up/lock-down handle system with two height settings, ideal for both my boyfriend and myself, as we are approx. 10 inches in height apart.
