I've really spent a lot of money for cases in the past, but this is finally over! The protective sheath of Glorytec keeps its promises! The envelope has on the one hand more eyes than the conventional cases in the market, thus ensuring ever for a better grip and seat. Even with the wind I need me stop worrying. Everything stays where it is and I have also been able to notice any "swelling". The material is completely waterproof and keeps even the strongest rain was. Our complete 7teilige outdoor furniture is including space and is protected. Ok, now we'll have to wait for the winter yet, but based on my previous, many years of experience, I want to say before, I probably should not worry about me. Highly Recommended
