Is this a normal life span of a windsock or would
another type last longer?
Thank you,

Jimmy,

I usually get at least a year out of mine. It seems that UV is hard on them
color-wise, but what seems to me to be the most damaging is freezing rain. It
gets frozen solid and then the wind kicks it around, cracking the ice on it and
causing the fabric to "crack" too. The ones from oil companies are good, as
noted, and I've also gotten them from Aerosock:

I've always had best luck by taking them down when I'm not going to flying for
an extended period.
