I purchased PHYSEN Hammock, and I am very pleased with the product.
I used Bear Butt Hammock, and I am very pleased with the product.
When it feels chilly lying in the hammock with low ambient temperature, I would like to close hammock's open top. So, it would make sense to install a zipper so that hammock's open top can be closed. Please note that if you decide to create such a product, I would be happy to volunteer to beta-test the new product and provide you with feedback.
