waterproof leggings for tripod?

Does anyone have an life-hack tips for waterproofing tripod legs. Any kind of small/portable solution. Maybe a plumbing thing? Or plastic that is easy to source in that shape (three bin bags + elastic bands perhaps?)

I'm specifically talking about salt water, so more of a concern than fresh water. When not outdoors my big tripod is a hat stand so I'd rather it didn't get smelly sea water inside it.

My tripod is a very very very very old Gitzo model (possibly as old as me) - but has the same leg design as the current models. Tubes with twist/lock.

All I can think of is three condoms but they're kinda slimey and not long enough.

Bicycle inner tube. Easy to cut and glue.

Super answers - thank you!

I think the bike inner tubes will be my first try - will post images one day of the set-up. Will probably aim for one per leg and rather than seal the end I'll keep it long (twice the length I need) and fold it back up the leg to elastic band tie it (this will create a seal).

I'm not going deep, welly boots on though. But even at ankle deep or just on wet sand I know my tripod would suffer without some effort to seal.

But I'll also visit the DIY store and see what plastic pipes/tubes they have.

Thanks again.

How about Kase Waterproof Tripod Leg Covers? A set of four cost SEK 170 or roughly GBP 15. Can be seen on this swedish site (use google translate): https://www.photax.se/product/kase-waterproof-tripod-leg-covers

I like that there is an official product for this ... gonna try the inner tubes though.

I'm not sure what my old tripod is made of and how water tight the feet are, I'd only be foot/ankle deep at most but it destroys any normal-ish foot wear. I'm more concerned with the smell of old sea water (getting inside the tripod) really. I've had this ridiculously big tripod for about 15 years and have only ever used it in the studio so time to try it outdoors.
