Got some new packs off of London Bridge during a sale not that long ago.

Changing out an older military pack to these I almost forgot to hit the new pack with Camp Dri.

It's not just for tents, you can use it on gear like backpacks, etc. and it will help shed water from them as well.

Packs, med bags, your boonie hat, your sill nylon tarp, your lightweight commercial type boots, etc. Use it on all of these to help the water resistance.
