Tents tear, lantern mantles fade, zippers fall off track. Overcoming these and other backcountry breakdowns requires you to be equal measures seamstress and handyman. With a well-stocked repair kit and the skills to fix anything (in this case a faulty zipper), you'll be well armed to survive and thrive in the woods.
Step 1:** Most of the time, a zipper that separates or won't close can be blamed on the broken or worn slider. This can often be fixed by gently squeezing together the bottom of the slider's wings with pliers. Crimp the top and bottom halves on both sides together slightly, testing the zipper before crimping again. If this doesn't fix the problem, you'll have to install a replacement.
