Our favourite fusion of all time, the Monsta Box combines all the best parts of our much loved Monsta and Blak Box models. It falls right in the middle as a perfectly balanced daily driver that you can rely on to grovel whenever necessary, but also enjoy some of the most fun & rippable conditions imaginable.

The new Monsta Box 2020 has more rocker and a narrower outline than the Blak Box 3, while it's fuller and flatter than the Monsta 2020. This gives it well blended curves to hide foam where you need it, without getting in the way of performing at a high level. A smooth single to double concave with a touch more depth creates lift in sub-par conditions, but allows you to remain in control when the waves turn on.

Whoever you are, the Monsta Box over delivers in several crucial parts of almost all surfer’s year round quivers. It’s the step down our Traktor Team use when the conditions don’t quite call for a Monsta. It’s the go-to when our friends who are lucky enough to surf every day want a performance board for smaller waves or less than pro abilities. And for the places and seasons that don’t get a lot of quality waves, it’s a forgiving option that will help you surf your best regardless of average conditions. The Monsta Box 2020 is our most popular hybrid, and now it’s better than ever.



Medium low entry and exit rocker, with a bigger sweet spot under front foot. Overall height is the same as the original Monsta Box, placement of the curve has just been pushed more to the ends of the board.

Fin setup

MONSTA BOX 2020 Round comes stock as a 5 fin. Alternative setups are available with custom orders.

Rail type

Monsta Box 2020 has medium full rails. This performance based rail shape allows for precision when the right section stands up, yet has enough volume to get you through fat sections or avoid catch in chop.
