I've always left my inner tent door open, to allow animals to explore the tent without the need to chew through it.
Unfortunately. on the last day of a recent trip, an animal (probably a ground squirrel) came into the tent and chewed 6 small (~1 cm) holes in my down sleeping bag.
I've tried repairing one of the holes with a patch of tenacious tape, but I'm not convinced the tape will hold; after stuffing the bag, the tape seems to come up on the sides.
In the past I've sewn across the hole and used urethane to seal the repair; but these holes are a bit wider, with masticated fabric on the sides.
Any suggestions?
