Sometimes, clothing made of some "poly" or other, smells no matter how you wash it. I am not sure of the exact name of the material, but have bought sports wear like that in the past.
Even freshly washed, it still smelled.
If you can manage to wear cotton under it when new the smell will not develop, ime.
Just went into my wardrobe to retrieve an old top, part of a work uniform, made of that material.
Never wore it for 4 years, was washed, put away for painting purposes.
Will you believe it? It still smells faintly of perspiration!
The label says: 100% polyester.
Yeah, I don't know what it's made from but it does smell if it's done on a 30 or 40 wash, although it does state it needs a 60 wash. The ONLY item of clothing I own that needs a 60 wash....
Yeah, I can see why although once it's done at the proper temp it's fine.HH stuff is nicknamed smelly hanson for a reason, you're not the only one with this problem.
I haven't seen it mentioned yet, but how soon after wearing it gets washed also plays a part.
It's one of these:

Warm as anything which is annoying as it smells more if you sweat, but being warm makes you sweat....
