While recently talking a customer through various running pack options, I found myself yet again explaining a big tip I discovered the hard way a few years ago – so I thought I’d quickly share it with everyone, just to save somebody somewhere from the disaster I once so narrowly avoided.
I used to think that zipping a double zipped bag so that both zips sit right at the top of the bag was a safeguard against contents falling out. I assumed that gravity would keep things sat neatly within, even if the zips crept a little. Not the case. If there’s movement (which there will be) or pressure from a very full pack, the zips move apart quite quickly and before you know it, the contents are forcing the opening to gape more and more, with the zips sliding further and further apart.
Soon, if you’re lucky like me, you feel your £200 worth of jacket tickling the back of your knees and discover soon after that behind you is a trail of valuable items you might otherwise have lost for good.
No – you should in fact try to pull both zips right around to one end or the other. The bag seems to hold itself closed a lot more effectively and even if the zips manage to defy gravity and separate, the contents of your bag can’t tug the opening wider in quite the same way. There have been two occasions where my same pack (pictured) opened itself and threatened to launch my kit. Both times, I noticed just in time, or was yelled at by a concerned (and very sporting) fellow competitor during a race. I have not once noticed even the slightest movement from the zip when done up the way I’m suggesting. Make of that what you will.
