One of my characters is stranded in a forest with almost all of of her belongings, and she must travel the 40 kilometers (~25 miles) on foot to reach her destination. She leaves most of her things behind, taking only the essentials/things she'll need once she reaches her destination (--her belongings consist mostly of what the average teenager might pack for a boarding school--she takes her phone charger, deodorant, most of her packed daggers, and two changes of clothes. These are carried in her backpack.) She also has archery equipment and a short sword and several throwing daggers on her belt.
But she can't bring herself to leave her bear pelt behind--it's her equivalent of a teddy bear, and she's stubbornly sentimental. So she drapes it over herself like a cape (the bear's neck is cut so that it fits snugly over her head) and begins walking.
Female black bears can weigh between 100-250 pounds, and males 130-500. These numbers are for fully intact bears, though. I can't seem to find any reliable info on one that's been skinned. I would rather the pelt be of a male bear but if it's unfathomable that the heroine could manage it I'm okay with it being female.
It's late August, the climate in this particular location in the world at this time of year ranging between 24-29 degrees C (75-84 F). Our heroine is an eighteen-year-old demigod who's been training her entire life. There is no time limit--she can take as many breaks as she needs. Should she run into a combat situation, she would remove the hide. How heavy is the pelt, how quickly would one dehydrate themselves / die of heat stroke (assuming she has an unlimited water supply) and how likely is it that she'd survive the 40km walk?
