Living in a fifth wheel, I have to store some of the bikes outside. I've used
various covers. This is the best so far. Less than the cost of two individual
bicycle covers which are not nearly as nice. Very roomy. May handle three
bicycles. Easy to cover the bikes with, compared to the individual bicycle
covers. Very high quality.
