Zippers

Recommended Posts

hey,

i just started jumping a PF Venom Power, the zips which encompass the MLW are different to my other suit which is a sqrl.

i liked the little bungee round button attachment and got thinking about making some sort of elastic toggle i could thread through the zip.

my question is.... 

what are peoples thoughts on providing a flexible anchorage between the two zips vs relying on the locking ability of the zip and just use the string to assist in a failure situation? if i copy the sqrl type the tension effectively lifts the lock off the zip .

 

here's the zip -

cheers!

Yes some people do that. I've jumped Tony Suits products that use a similar system. Tying the two zipper heads together is in my opinion the most secure version of securing the zippers because if you run the cord through the bottom of the zipper, instead of the top as pictured, you can tighten them up enough that there is absolutely no gap between the MLW and the zippers which is not the case with any other system I've ever seen. The main issue is this method is a bit more slow so it takes more time to take suits on and off which is why I suspect it's not more common.

Personally I dont suggest the S biners method. I've tried it and found those biners are not that strong and I've broken a few. Also, since they are just metal and not elastic cord, there will always be a gap between the MLW and the zipper head which is not as ideal. The ideal solution is one in which there is never any gap between the MLW and zipper heads.

On any suit with the dual zipper/innie-outie setup you can also just fix/close the bottom zipper permanent with a few stitches. This means only the top zipper is able to move.

This severely deminishes the chance of the zipper (even with connected string or elastic) opening up and swallowing handles. As that is quite easy when both zippers are able to move, but happens a lot less with only one moving freefly.

I've got my PF Strix setup with a 'classic' single zipper (ordered as such), as its much less fuss in skydiving use with gearup and general use, as well as a bit more comfortable in fit.
