Your CO2-compensation payment flows into climate protection projects and offsets 100% of the CO2 amount incurred for production and transport for each item.
The compensation amount results from a mixed calculation for all products and is 18 cents.
The CO2- and plastic-compensation are part of the HAND.IN.HAND. initiative. We regularly provide information on the development of the initiative and in the area of sustainability on our website and in our newsletter.
With every voluntary Plastic-compensation, the amount of marine litter and plastic equal to the weight of the ZWEI product is taken from the sea and sent to a recycling process.
The compensated weight is determined based on an average weight of all ZWEI products.
The Plastic- and CO2-compensation are part of the HAND.IN.HAND initiative. We regularly provide information on the development of the initiative and in the area of sustainability on our website and in our newsletter.
Weatherproof through autumn and winter
HYDROFLEX® is a water-based and sustainable PU (polyurethane). It is much more environmentally friendly in production than conventional synthetic leather. No environmentally harmful solvents (DMFA) are used in the production process.
Robust and comfortable at the same time!
HYDROFLEX® has a number of other positive properties in addition to its sustainable production: The surface is very smooth, scratch-resistant and 800 percent more abrasion-resistant than conventional imitation leather. Thanks to the robust nature of the material, our bags and backpacks are a reliable companion. A long service life is an important factor in conserving resources and protecting our environment. Furthermore, the material is very soft and easy to wear on the shoulder.
We make no compromises in the choice of materials. Therefore we are in constant exchange with our producers to improve our materials and products. We are convinced that good quality and a clear conscience need not be a contradiction in terms. HYDROFLEX® is the result of a search for the best and most sustainable material for a backpack that passes every everyday test. Our claim was and is to offer a high functionality, where neither the product nor its production unnecessarily pollutes the environment. We have found this material with HYDROFLEX®.
HYDROFLEX® does not require explicit care. Dirt can be removed with lukewarm water, mild soap and a sponge. Thanks to its PU coating, the material is water-repellent and does not require additional impregnation.
