Instructions

USE AND CARE OF URSACK

DO

Cinch the cord lock tight so that there is no opening at the top of the bag.
If food is visible, you have packed too much in. 
If you can see it, a bear can get it.
Tie URSACK up a tree trunk or to a strong branch so that it can't be crushed or stolen. Bears have been known to chew through 5 inch branches to get to food.
NOTE: In some areas, such as parts of Yosemite, Sequoia-Kings Canyon and Inyo, you are not allowed to tie Ursack to a fixed object. There, you must use a Hybrid placed on the ground a safe distance from camp.
Always check trailhead regulations.
Tie URSACK using a figure 8 knot, so that it can be untied easily. If you need help, try this animated description of a figure 8 knot.
Keep any food item that could leak in a plastic bag inside URSACK. Even though a bear may not be able to penetrate URSACK, he may be able to crush the contents. If URSACK does get crushed, there won't be a "food reward" that can be licked from the outside.
Machine wash, no bleach line dry
DO NOT
Do not keep URSACK in camp.
URSACK must be secured to a fixed object that is a safe distance from your camp site.
Do not keep URSACK in or near your sleeping bag or tent.
