Montana Pitch Blend for sure! It conditions and waterproofs- and smell like natural pine pitch rather than chemicals and/or petroleum by-products. I've been using this product on my armguards, back quiver, possibles bag and hunting boots since the early '90s with great results. All of the above mentioned hunting accessories are still in fantastic shape and I believe that this speaks volumes about the usefulness of this time tested product. I get mine from Schnees Boots out of Bozeman, MT. I believe it is still available from 3-rivers archery as well.
