You can, but I’d save it for patching things that are cuben, and use tenacious tape on other things. But I think they should work for most things. The mesh pocket thing was a bit unclear. I won’t be home until tomorrow evening so can confirm properly then, but it’s a noseeum mesh pocket (for inside a shelter) that’s sewn or glued (can’t remember this detail) to a strip of cuben tape. It wouldn’t be suitable for anything high abrasion (Eg a hipbelt pocket) more of a pocket for through the night doo-das. It came with my cuben solomid a couple of years ago but it felt superfluous so I never used it.
