I've got a bunch of patch kits that contain yellow "Propatch"

was inside an extra plastic wrap and all, didn't help. So we
had to use my spare tube.

Do you guys know a brand that is better and where a bunch of
these little tubes could be bought sans patches? Not so much
for me but for other riders because many reported similar
problems.

I have found that new unopened tubes last forever something that
a lot of Rema did not. Or at least none have failed in four years
of storage


Maybe this Propatch tube was just a dud then. It had the same
puffy appearance and feel to it as usual but when puntured ...
phhht ... could be compressed to full flat without anything coming
out.

I still have about 70 or so of those patch kits and they are fine so
it much be something to do with heat.


That might be. You live near the coast where it rarely goes above 80F.
Here we have weeks in a row where it's above 100F during the day and I
ride in almost any weather. Even at 105F in the glistening sun when the
bike paths are almost empty. When I grab another bottle of water out of
the left pannier after a few hours it's really hot. Everything bakes.
