Like that there's a hefty zipper AND a bottom tie
"I bought this last month and didn't need to use it until this month. My old green colored plant covers were getting worn and the tie rope kept breaking, so I ordered these to use this year. The 6 foot one worked well to cover 2 tomato plants during 3 different nights of frost. The larger sized one was too wide and not quite long enough to cover the 4 larger containers properly, but it did cover them enough to protect them from the slight frosts we've had during the last few weeks. Now I have to condense those containers and see if I can rearrange them to cover them for the winter."
