McKlein's R Series features great laptop backpacks, messenger bags, and wheeled and non-wheeled briefs. The wheeled briefs include the patented removable wheel and handle system. These bags can be wheeled, carried in-hand or over the shoulder. When you prefer to carry it, simply remove the wheel and handle system by unzipping the customized mating zippers and leave it behind so you can relieve yourself of the additional weight. Carry it using the padded leather grip handles or the ergonomic, no-slip body contoured shoulder strap.
