That's it exactly but holy cow, sixty bucks? "A Buyer's Paradise" is irony taken to level three.
Now I feel better having only paid two or three times too much for mine.
These would be cheap to resurrect, as the fabric itself is not expensive (basically, soft Tyvek housewrap). Hazy memory but I think my original was something like eight bucks but even then they were hard to chase down, maybe because they were marketed to picnickers and thus, seasonal items.
Hey, I know, just staple a couple disposable hazmat suits together.
