Hi all,
Last sunday, after a beautiful day on botany the zippers of my prolimit session bag were not working.
Both sides of the zippers are opened all the time. The bag is only 4 months old !

Do you guys have an idea to fix that ?

If the problem is due to salt build up then have a read through this thread on Zip care....it will give you a lot of ideas.

Personally I would give it a good spray of WD40 and let it sit for a while.

If the problem is due to salt

No, there is no salt at all on the zipper, it's not jam. Both zippers are sliding right, it's just that the zippers are opened on both side of the ruler...
It's a shame that a 4months old bag need a zip replacement is there any kind of warranty on such bags ?

I am no sewing etc expert, but I thought when you move the slider and the zip doesn't close it means it si worn out. Usually takes a long timke for that to happen.

Therefore, they have used a low quality (or defective batch) of zippers if it wore out in 4 months?

I'd be taking it back for refund / exchange regardless of warranty - Sale of goods Act, item was of unmerchantable quality at the point of sale .... proven by the fact that zips on bags for watersports don't wear out in 4 months.
