Like all such products, they zip up easily. The problem is usually with unzipping when trying to attach it to the zip behind your neck. This product would be much better if it had a small but wide flat surface to use with your thumb to open the clasp. Or even it came with a small ring to attach to the zip. Sadly it has a thin grip so it often slips and snaps shut again when trying to clip it behind you. Cheap enough to throw away when I find a better one. I would buy the ZipHer but shipping to Canada is prohibitively expensive.
