When weight and space are your top priority, the Ursack Major XL is the bear bag you need for protecting your week's worth of food from creatures and critters in the backcountry. Created with nearly bulletproof fabric, the Ursack Major can withstand the sharp puncture of a bear's teeth so your food is protected on your expedition. And when your objective requires quick turnaround at camp, the 6-foot tensile-strength cord makes stringing your food on a branch a quick task during morning or night.
The light and compressible Ursack Major XL bear bag is made of bulletproof Spectra fabric to prevent bears from getting to your food.
