it's another one of those "it depends" sort of deals.hiking out West on open trails it might work just fine.back in the woods with snags everywhere mesh would be a branch trap.
a real pocket can hold anything,mesh is a sieve.
like it has already been said,someone put mesh on a pack to dry clothes on the move and it became a icon of hard core outdoor gear and spun off everywhere.the mesh pocket and a clip to hold bottles is that belt and suspenders deal-----
