If you're reading this the item is still available.
Here is a brand new fabric care kit specifically designed for Carhart, Scent-Lok & Cabelas Roughneck outwear. This will also work on any canvas, cotton or fleece.
The kit includes 10 oz. of the G-wash Cleaner that will deep clean up to 6 garments plus 9 oz. of the spray on UV Waterproofing that will treat up to 4 garments.
I have several of the kits available, just let me know if you need more than one.
