The streamlined design of the Stahlsac 34in Steel Wheeled Bag contains a sealed water-resistant compartment for keeping your wet, dirty gear separate from dry clothing and items. Quick-access zippers expedite retrieval times while the bright interior lining makes it easier to locate small possessions. An optional battery power pack is conveniently stowed in a designated compartment and a versatile add-a-bag strap for attaching a carry-on backpack or briefcase makes for easy travel at the airport. Sturdy all-terrain wheels and heavy-duty reinforcements provide durability that can go anywhere, from pier to concourse.
