When looking for a nylon hammock, it is important to consider the weight capacity, the length and width of the hammock, and the type of fabric. It is also important to pay attention to the stitching and construction of the hammock. A good-quality nylon hammock will have double or triple-stitched seams and reinforced corners. The fabric should be made of high-denier nylon, which is durable and tear-resistant. The hammock should also come with a warranty from the manufacturer.
