Big Bertha is MOBOT's original foam roller water bottle. The 40oz capacity means you'll actually stay hydrated, and the full-size roller works on big muscle groups like quads, hamstrings, and your back.
It's made from recycled stainless steel wrapped in EVA foam that's firm enough for deep tissue work.
Reviewers love that it's always with them, and it encourages them to roll out for muscle recovery as well as stay hydrated. Fair warning: it looks like a grenade, so TSA might have questions.

"I roll out every day with this. I recommend the larger size so you can roll out your thighs better."
