I went through this last year, and was told the red label Revivex, which is for hardshells (Outerwear) I believe. Simms has it for sale on their website, although label is black now. http://www.simmsfishing.com/site/revivex.html
Go for the 10 oz bottle. 5 oz is not enough from my experience.
The teal labled bottle is for soft shells, such as fleece.
Wash with gentle detergent such as Ivory Snow, hang and spray revivex on wet waders, then throw in the dryer on low – medium heat depending on dryer and care instructions on inside of wader.
