I have a few Arcteryx jackets of the leaf variety
all are totally waterproof and have survived years of hard use when culling, carrying out day long sojourns in darkest Cumbria and also at competitions
One of my jackets developed a faulty zip a month if so ago
Bearing in mind it’s over ten years old - I contacted arcteryx and was referred to their repairs facility (in Switzerland) who asked for images and brief description of the fault
A week later it was sent to their repair centre and less than two weeks after it came back with nee zip fitted and re proof - free if any charge
Cannot recommend this brand highly enough
