I always carry a spare tube with me in a seat bag but I almost never use it (I keep it as a last resort and generally patch flats when I get them). In fact, I eventually end up tossing the tubes because they get chewed up by the other stuff (mini tool, keys) in the seat bag. They also take up a lot of space.

So I'm wondering if anyone makes something like a lighweight spare tube that's vacuum-sealed in a compact package to reduce space requirements and protect the tube.

This happens w/ alot of spares. I use either a seatbag w/ a separate compartment or make my own divider using the plastic backing of the large "labels" of some new tires.

You can still wear through a vacuum seal bag. Would be good to keep the tube small. I would still put the tube in an old sock and double up the layers.

The Bontrager XXX tube (not sure it is still offered) comes wrapped in plastic and is very compact.

I'm thinking of using a vacuum pump fitted with a presta/schraeder valve, to suck the air out of the tube, and then continuing to use my old sock method to protect the tube.

No need! Just roll up the tube and press out the air. VERY easy with presta valves.

Thomson seatpost and stem bags are useful for carrying, and protecting, bits and pieces. They're a bit of a sales gimmick and would otherwise spend their lives at the back of the spares drawer..!

Using and carrying only slime tubes for the past three years, I apparently have forgotten how easy it used to be rolling up spare tubes to get all of the air out! Thanks for the reminder.
