if you're not carrying very much, maybe a lumbar pack would suffice? won't effect draw at all. are you wearing an orange vest? a lumbar pack wouldn't cover up any orange was it up
also you can get inexpensive orange panels that will attach to any daypack (or backpack for that matter)
This , I use a tenzing fanny pack that has shoulder straps to slip hunt to my stands and blinds. It is not blaze but is hydration compatible. It will carry what you want. It wouldn't take much to tie on a blaze bandana if that is a concern.
