Tech shirts stink

Sounds like residual stink.  I usually wear cotton to do strength training... I sweat in them but not even a 10th of what I do in my tech stuff that I wear running.  

Wash the cotton and its fine the next time I wear it, but the tech stuff can grow funky after awhile.  I've switch to using specific sport wash for the tech stuff and my stink issues are gone.

Penguin Sports Wash. It's the bomb. That stuff can get anything out of anything.

Alternately, add a cup of white vinegar to your regular detergent. Not as good, but it'll work.

Prowash Detergent

I bought some last year and use it on my tech clothes once every month. You only need a little bit, so the bags last awhile. My wife noticed the difference immediately.

I do the vinegar.  It's cheap and reasonably effective.  My oldest tech shirts are 7 years old.  There were times I had to beat them into submission before donning them (even right out of the laundry) and they're manageable even now. 

My older tech shirts kinda stink like vinegar already.

Sportswash and cold water in the machine on gentle (intermittent agitation for the spinner thingie).

I dry mine in the dryer, on cool, no dryer sheet.  Have some shirts that I have treated this way for over 5 years and they are fine.

That's what I thought, until I read an article/interview where a manufacturer rep stated that he never could figure out where the "don't put in a dryer" myth came from, and that drying with heat/tumbling is good for the weave.  Same guy that said not to use dryer sheets because the clog the weave and make a perfect home for stink bacteria.  I'm not certain which manufacturer, but I think it was underarmour.

Hm. Maybe I'll have to change what I wash mine with. I hate the smell so much I stopped wearing them. I now ride, run, and lift in tight cotton tank tops or t-shirts. 

What's the benefit of tech fabrics? I don't feel particularly cooler or drier when wearing them...

It might be okay for the weave, but it sure seems to break the elastic down a lot faster.

I used to have this problem too, but switched to a non-scented liquid detergent (Costco brand to be specific) and guess what ?...no stink !

This works best for me too.

we use the sportwash/hang dry method.  periodically my husband's stuff will develop The Funk (mine seems to be immune) - then we'll pre-soak it in sportwash and then wash it normally.

we have a rolling rack in the bedroom that's just used to hang workout clothes dry.
