Promotional InSideOut R-PET Cooler bag Koli This stylish and practical cool bag from the InSideOut Koli series is a smart choice for anyone looking for both functionality and sustainability. This beautiful Koli cool bag is made from environmentally friendly rPET, a recycled material that is not only good for the environment, but also ensures a robust and long-lasting quality. The spacious main compartment is equipped with aluminum insulation, which keeps the contents cool and protected from external influences for a long time, ideal for picnics, shopping or on the go. Thanks to the sturdy zipper, you can easily open the main compartment and keep everything well closed, so that the coolness is optimally maintained. The front pocket, although not insulated, is perfect for printing a logo or company name.
