There's also the kind made from rubber granulate, oozes along the entire
circumference. Cheap, as I think it's old tires/tyres. Frostproof, weatherproof
over several years at least, IME. Requires mains pressure though.

I currently use some of that for a rather dry part of my garden.
It works well, though after a few years the pipe is beginning to
fail in places. I can cut out the leak and rejoin, but unless I
am lucky, inserting the plastic fitting splits the pipe again. I
chased one such failure last week for quite some distance before
I got it safely (I hope) rejoined.
