I’m on my 2nd Ortlieb handlebarbag. The first lasted almost 15 years. The last years it wasn’t waterproof because the corners of the lid got torn over the years but I had used it several times a week (almost daily) April to November during these years. I put some gaffer tape in some places on the inside of the lid
My ”new” is made of a different material and the form of the lid should prevent it from wear as the old one.
The lid overlaps well and fits very snugly but I guess it can’t 100% waterproof in a really heavy rainstorm. I have however never worried keeping my phone in the bag during trips in normal rain.
The Ortlieb bags , but no bike, is what I have right now. The bike I’ll get for spring will definitely be equipped with a KlickFix mount for my handlebar bag.[/QUOT
