After just two winters, my cover is tearing like paper! It is a "triple laminated polyethylene double-stitched" but it is ripping at the slightest tug!!! Definitely need to replace it, but looking for suggestions to avoid recurrence in a few years. One theory - I used it for a week's vacation in July. Could a week in the summer sun make that fabric so brittle? Looking ahead, I intend to use my cover for winter AND for 7-10 day summer vacations. Is there a brand / type you can recommend for this? NOTE: I am not open to leaving it uncovered for winter or during summer vacations. Thanks in advance for any feedback!
