Barbour zips are high quality and very rarely develop a fault. However as many are double zips, getting the knack of doing them up may be tricky at first. Ensure that both parts of the zip are as far down as possible and that they are clicked together. Then ensuring the zip pull remains at base insert the other side of the zip and then do up. Occasionally jackets are returned to us with zips which customers believe to be faulty, in the vast majority (99.9%) of cases zips are not faulty, and it’s the technique which is not quite right.
