URSACK - Major Bear-Resistant Food Sack

The URSACK Major utilizes ultra-high-molecular-weight polyethylene (UHMWP) fabric to resist bear attacks. This material is extremely tough and helps prevent bears from accessing the contents inside. While it doesn't make the food completely invulnerable to crushing, it significantly reduces the risk of bears reaching your food. This makes it an excellent choice for backpackers who need a lightweight yet effective solution for food storage in bear country.

The URSACK Major measures approximately 24 inches in circumference and 14 inches in height. With a capacity of 650 cubic inches, or about 10.65 liters, it can hold approximately 37 freeze-dried servings. This size is sufficient for extended trips, allowing you to store enough food without adding significant weight to your pack. Its compact form ensures it fits easily into your backpack while still providing ample storage space.

The URSACK Major is ideal for storing dry foods such as freeze-dried meals, snacks, and other non-perishable items. It is not designed for storing liquids or perishable foods that require refrigeration. When packing, ensure that food items are sealed in odor-proof bags to further reduce the risk of attracting wildlife. This approach helps maintain the integrity of the food and minimizes the chances of bear encounters.

Unlike traditional bear canisters, the URSACK Major is lightweight and flexible, weighing only 7.6 ounces. This makes it easier to pack and carry, especially for long-distance hiking. While canisters offer more crush resistance, the URSACK provides a good balance of protection and portability. However, it's important to check local regulations, as some areas may require hard-sided canisters.

To maximize the effectiveness of the URSACK Major, it should be tied securely to a fixed object using the included six-foot cord. The cord has a tensile strength of 2,500 pounds, providing robust security. It's crucial to tie the sack in a way that prevents bears from dragging it away. This setup not only helps keep your food safe but also minimizes the risk of wildlife becoming habituated to human food.

After each use, the URSACK Major should be cleaned and inspected for any damage. Check for tears or abrasions in the fabric that could compromise its effectiveness. Cleaning involves rinsing with water and allowing it to air dry completely before storage. Regular maintenance ensures the sack remains in optimal condition for future trips.

The URSACK Major is suitable for use in many wilderness areas, but it's important to check specific regulations. Some national parks and protected areas have specific requirements for bear-resistant containers, and in some cases, hard-sided canisters may be mandatory. Always verify the rules of the area you plan to visit to ensure compliance and safety.

The URSACK Major is designed to withstand a variety of weather conditions due to its durable UHMWP fabric. It can handle rain and moderate temperature fluctuations without compromising its integrity. However, in extremely cold conditions, the fabric may become less flexible, and in heavy rain, additional waterproofing measures, such as using a dry bag, are recommended to keep contents dry.

While the URSACK Major offers significant protection against bears, it does not make food completely crush-proof. Bears may still be able to crush the contents, although they won't be able to access them. Additionally, it requires proper tying techniques to ensure it remains effective. Users should be aware of these limitations and plan their food storage strategy accordingly.

The URSACK Major supports Leave No Trace principles by minimizing the impact on wildlife and the environment. By securely storing food and reducing the likelihood of wildlife encounters, it helps prevent animals from becoming habituated to human food. This not only protects the animals but also preserves the natural balance of the ecosystem. Using the URSACK responsibly ensures that future generations can enjoy the wilderness without adverse effects from human activity.
