Planning a PCT Thru-Hike. Will this bag be accepted by the park services and rangers along the way?

Asked by: nicktallman
Each park is different so you would need to check with each park individually, but generally most parks require actual bear canisters instead of a bear bag, so this item will not work.

Will this fabric also withstand rodents as well? Haven't really had an issue with bears as so much rodents climbing down the rope and chewing a hole in the bag.

According to Ursack there is no good way to test the critter resistance of the Major S29.3 AllWhite Bear Bag, but so far feedback has been excellent. ​ If you are only concerned about smaller critters than bears you may want to consider the Ursack Minor, which is designed specifically to keep critters out, but not bears. http://www.ursack.com/product/ursack-minor/​

Does REI carry the cord used in the Ursack Major for purchase by the foot?

Asked by: JHSX
​The Major S29.3 AllWhite Bear Bag comes with a ¼" polyester drawcord. Due to the strict testing protocol we suggest contacting the manufacturer for any replacements parts or repairs.
