Actually, it's probably you that smells (or, more accurately, it's you that's making it smell).
Different people have different bacterial flora, and exude different body chemicals (stress is a good one for making stuff stink). Some could wear a fleece for weeks, and it wouldn't smell. Some can wear a fleece for a couple of hours and it will ming. Seems you're one of the latter...
Does it smell even with a merino base layer under it?
I'd suggest you try TC's suggestion if your washing process isn't leaving it smelling fresh.
