I sweat like a pig. I wash my gi as soon as I get home and hand dry it immediately and my school is only 5 minutes from my house, so it is not like the gi festers in my bag or in the washing machine. But on the collar it has an odd smell, like sweat but not really. Almost like a burnt smell. A few of my sweatshirts from the gym have the smell also, no matter how much I wash them. Always around the neck. I load it up with fabric softener, use all kinds of detergents. Still the same thing. Anyone know what this is? or happened to them before?
