My Yetti purchased August last year, of late I've noticed that the feathers are coming out through the material. I always find feathers sticking out through the material.
I own a old down sleeping bag that's doing this, the bag is 5 or 6 years old.
I'm surprised the Yetti is doing this.
It's well cared for, never stored inside the stuff suck, the only times it's kept in the stuff suck is while out hiking.
It seams to be getting worse with time.
