I like the product it seems like it should be more durable, but perhaps in the Colorado sun and snow it isn't what it's cracked up to be.  I've bought 4 of these now, and they don't seem to last one full season.  I've gotten holes in the fabrics from sitting out doors, no one has pulled or intentionally torn at them, but they keep ripping.  Not sure what other options are available that will have more durability.
