hygroscopic bike seats.

ya'll know it:
left the bike outside just one rainy nigth. next day the seat is wet. normally it dries within 3 days (implieing it doesnt rain anymore) . but if theres just an itsy bitsy tiny hole in the cover - the plastic-like stuff covering the foam-thingy upholsterin ya posterior - ya screwed. it will absorb any water molecule it could get n never ever will return it. i left my bike outside 3 fuckin weeks ago. it didnt rain any drop for 3 fuckin weeks. the seat is still soaked! every time i rode my ass gets wet. what is inside a bike seat? a sponge? kitty litter? (wait - that would hold da water). dunno which material they crafted there, but i hereby officially propose to use it to make reservoirs - its water-holding capacity is unreachable. if ya need water - squeeze it. its so simple. i think i should perhaps patent it.
until then: to all fellow sufferers out there: do you know how to dry it out? blow-drying doesnt work at all...
