Zippers are designed to give you easy access to items that have been enclosed for safety and protection. But factor in pair of gloves covered in various fluids, and suddenly using a zipper becomes quite more difficult.
The solution is rather simple – place plastic cable ties to the ends of your zippers. This will provide a finger loophole for extra grip whenever your hands are gloved and bloody. Just tighten the cable ties to the right size and place a piece of masking or electrical tape to hold the tie in place.
You can also color code these cable ties so there are easily visible and designate different zippers for different compartments.
