Condition: Excellent condition, lightly used. A couple of very small cosmetic hits on the rail (pictured)

Description:  The Firewire Boss up is the bigger brother of the S Boss, Kelly’s first-ever midlength.

Designed by Dan Mann in partnership with Kelly Slater and Kevin Schulz, this utility midlength 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.

Condition: Excellent, lightly surfed condition. A couple of very tiny cosmetic paint chips to the outer paintwork on the tip of the tail and nose.

Additional Info: This is a used board, and we’re excited for you to check it out! We do our best to describe the board’s condition, including any repairs, features, and signs of use. Please review the product photos and description on our website before placing your order. We’re happy to provide additional images, but they may not fully capture the board’s appearance. Some cosmetic differences may become evident once you have the board. Since we don’t accept returns on used surfboards, purchasing sight unseen means you acknowledge these potential discrepancies. If you have any questions before purchasing, feel free to reach out—we’re here to help!
