Perhaps this has been mentioned but it does bear repeating:
The plastic/rubber/silicone zipper pulls that have a rough, grippy surface like stubble or stickle bricks are bad for fabrics. I have found that they tear up the surface of softshell and the inside laminated mesh of goretex proshell easily. It gets really bad under the hip-belt of a pack.
They were introduced about 5 years ago and are being phased out, I think; most companies are using a smoother version now but not all. Replace them with things like cord, shoe lace or reflective ribbon tape etc.
