The Bailout replaces the Metolius Stomp as Metolius's entry level pad. It is different in many key ways. The Bailout is four inches thick while the Stomp was only three inches. This addressed our main dislike of the Stomp, which was that after a few months it became way too soft and did not offer enough protection. The Bailout also has auto upholstery in the center and uses more burly fabric. The different foam layers are now welded together. There are three layers of foam where the Stomp only had two.
The Metolius Boss Hogg is the next step up. It is the same size but comes with and extra half inch of foam and auto upholtry across the entire top. It also comes with reinforced edges (cool but not really necessary) and a one-hook closing flap that is fast to use and keeps small things from falling out. However, the Boss Hogg is almost two pounds heavier and not as good at holding big stuff. We generally put all our shoes, chalk, water, and extras in a small backpack and put that inside the pad. We found the Bailout was much better at handling this. If your pack is too big the Boss Hogg just can't hold it. The Boss Hogg is also $60 more expensive, so we generally think it's best to get the Bailout and then spend money on a truly big and deluxe pad.
The Bailout has been replaced by the Metolius Session. See below for additional details.
