The zippers of your tent are as important as your tent itself. Fortunately, there are several tents that have durable zippers and that are available in the market. For instance, the best solo tent I have makes use of extra large #8 zippers.
Unfortunately, some have zippers that are, by nature, very delicate and which quickly breaks because of rust, corrosion, or wrong movement.
If this thing happens, do not panic because there are several ways on how to fix a tent zipper which I will explain and discuss further. As you read and come across each step, you will find out that these methods are very effective yet simple and easy-to-do.
