Last week I tubed up both the tarp (mesh tube) and the hammock (LST) and hiked up a cliff...frkn rain came down in dixie-cup sized droplets and it took me 20 minutes before I could negotiate the slickened sand wall to get back down to my camp...UQ was dry as a bone!
I am definitely in love with a Slug.
At first I thought it should be smaller but, naw, it's perfect. If it were tight it wouldn't be so easy to slide on. And it goes right down in the bottom of my pack, so as I add in the objects that do have a shape, it magically fills up the unused space and I wind up with a cohesive load.
When I take the zPacks Zero I pull an end of the Slug up against my back so I don't need to carry the sit pad in there - and never notice any corners poking me in the back. When I carried the sit pad, that felt like more weight and bulk.
I still want to make myself a brownish-yellowish one and put big black polka dots on it so it looks like the UC Santa Cruz mascot Banana Slug.
