Ridgeline rata bumbag $40 (olive, not a fan of blaze or cammo) + camelback hydration bladder. Enough space in the large bumbag pocket to fold a soft shell rain top, but if I take a fleece bush shirt that gets tucked into the stretch cord on the back of the hydro pack.
Plan on sewing straps and buckles to bumbag and bladder to stop the bumbag from slipping down.
Ridgeline has a hydro pack with storage, butit lookalike it has a hip belt, so not sure how that would work with a bumbag.
