Just wondering what most of you are using as a rear rest while in the field hunting. I have a Javelin Long Bipod that I use as a front rest and I love it because it's light and easily detachable. I have a Bipod Big Buddy and I like the concept of it being light and it doesn't take up much pack space and I have many sandbags that I can use too. Sandbags are heavy and take up a lot of pack space, Bipod Big Buddy, I practiced a lot with, and do well with out to about 600 yards. Just looking for advice on a rear rest that easily deployable and that is light and compact enough for backpack hunting.
