A lot of mine were wore out, holed up, and non functioning after 5 years, much less 35. People make a big deal outta not being able to wash it. Just as stated above, if you have the kind that has to be handwashed. Dry it hot and whip it out. I know I'm not the only one to have this happen, but by the time you wash your high tech garmits alot the shrinking that has happened to them is just as noteable as the wool. But nobody addresses that.
I had shirtails to short to stay tucked. shirt sleeves are too short. Holes in the shirts of the "new fabric". All caused by shrinking, piling, and bascially falling apart due to being worn out. And the stuff stinks when you get it dirty or wear it for a couple days without washing it.
To each his own but I been down both roads and the wool route is so much better for ever use. One more tidbit for you fellows down south. A good insulator protects from heat as well as cold. So if you are wearing a long sleeved garment, I promise you wool will be cooler and more breathable than any synthetic. Those sweaty days would feel so much better in a light wool long sleeve versus a stinky, wet, polyester or cotton shirt. Your missing out and don't even know it. There is a reason top of the line suits and warm weather clothes are made from wool as well!
God Bless
