Ultimate function meets refined styling in Hartmann's Stratum Collection. Featuring superior lightweight 2520 Denier Ballistic Nylon, this collection is complimented with handsome top grain leather accents, TSA combination locks and high gloss nickel-finished hardware. In addition to the fabric luggage styles, the Stratum Collection now offers textured ABS spinners. These extremely durable cases provide maximum impact resistance and absorb impact by flexing when under pressure. Whether you are navigating the corporate ladder or heading out for the holidays, Stratum will keep you well-equipped for the rigors of travel.
CONS: bought two navy color ones in october, after first trip the luggage looked 5 years old, it scratches easily and it becomes light blue. After 3 trips, airline fixed it because of broken handle, after 5th trip airline replaced it because of broken handle. Not what i expected from Hartmann. Need to open on the floor because hotel luggage holder won't hold it since its a two sided luggage.
