Can I appeal to tackle manufacturers to consider designing/using zips on fishing equipment that actually work or at the very least outlast the equipment/clothes they are fitted to. The number of bags, coats, rod quivers, etc I have bought over the years that have had the zips fail while the rest of the item is still serviceable is innumerable. The latest in a long line of failures is a Korum mat bag, a great idea and in every respect a good product except for the zip. This is the second one I've had, the first had the zip fail within a month, it's replacement lasted a bit longer, but again the zip has failed. I have a small Chub roving bag which suits me fine, but every zip on it has failed. I've had various weatherproof coats, bib and brace trousers over the years made by different makers, cheap and expensive, which have not worn out but have had to be replaced because you've guessed it the zips have failed. Strangely the cheap ALDI fishing clothes seem to have zips which outlast the wear and tear, so if Aldi can manage it, come on the big names in tackle manufacture make gear where the zips last. Rant over, on reflection I could just be heavy handed with zips!
