I use a Samsonite Lite-Cube spinner.
And I regurarily pack 5 socks, 5 boxer briefs, 2 t-shirts, one pair of shorts, running shoes, shoes, 2 ties, 5 dress shirts, two pair of trousers, an extra jacket and my toiletry case, which granted is nothing like my wife's but still contains electric toothbrush, electric razor/haircutter, deo and some other stuff.
