This is probaly the piece of clothing I have that gets least use. I tend to avoid deep forrests with mosquitoes. But every once in a while a trip gets planned where this is warranted and then I'm truly happy I have it.
The permethrin it's treated in does not last forever, and I am not really a fan of chemicals. Often use natural lemon oil instead. So while I'm not sure I'll ever buy another one, I have thus far decided to keep this. Should still have about 20 years of permethrin left if used at the rate it's used now.
