The Slater Designs Boss Up I-Bolic Surfboard is the bigger brother of the S Boss, Kelly's first-ever mid-length. Designed by Dan Mann in partnership with Kelly Slater and Kevin Schulz, this utility mid-length is the most well-rounded and versatile shape in the Slater Designs range, crafted to cruise across weak wave faces and grind through cavernous overhead tubes.

The Boss Up is the board you would travel with if you could only bring one board with you. Your one board quiver with maximum performance in a purely versatile package. Recommended to ride roughly +13 liters more volume than your standard shortboard, paired with the KS1 5 Fin Template configured as a Quad.
