Once again I typed a perfectly composed paragraph explaining what fatty acids, oils and perspiration do to your suit. Once again this board timed out the thing before it posted. The short version, Your suit is worn out. 2 to 3 years is about the best you can expect from these things with moderate to heavy hunting. Home dryer temperatures will NOT release these non volitile substances from your carbon. Care must be taken at all times to keep down contamination. With each use more and more non-volitile substance are introduced that deteriorate performance. Sorry for the short version. The last post was worthy of a double Kudo deer head.
