http://www.hggear.com/flakjacket.html I just received via Levenger a really nice sleeve with construction that sets it apart from soft sleeves. Check out the link and see their approach that has a multi-layer construction. Coated ripstop nylon, corrugated armor and foam. Looks pretty shock resistant to me. I'm still waiting for my 3G so I can't tell you how well it fits. Assuming Levenger is right about fit this one should be a keeper.
