For you people who wear wool jerseys, how often do you wash them? After every ride or only when they are really dirty and stink.

Good wool dose not develope the "stink" that modern fabrics do. I only wash mine when It really needs it. (you will know it when it dose). That being said I do wear a base layer between skin and the wool.

Wool socks on the other hand get washed after every use. I have 3 pair of knee high old school cross country ski socks.

Wool glove liners I may wash at the end of the season, and the same goes for the balaclava.

I have a pretty good amount of Ibex and Smartwool bits and every one of them is wash and wear. Mind you I have a front loader, but they all get washed the same as my other bike clothes: Wash on regular cycle with a second rinse and in the dryer on low heat. Wash them as often as you feel the need. Good modern wool holds up very well.

regardless of whether they smell or not, i wash all my wool cycling clothes after every ride, on gentle in a front load washer, then hang to dry. Socks, base layers, jerseys, etc.

That's a pretty black&white view of the world!

I usually don't wash my wool jersey after every ride -- but I also never wear it without a base layer, and never in warm weather, only on cool or cold rides. I still wash it after two or three rides, long before it even gets an opportunity to get stinky.

you can handwash in a bucket while you shower
