Two minds combined. Rob Machado and Dan Mann have created the Mashup: A melding of each of their most popular designs; the Seaside and the Spitfire. Both board designers have spent time mixing and matching their favorite elements of each shape, and they’ve landed at something that goes fast in weak waves as well as a Seaside, and also drives vertically in good waves as well as the Spitfire. The Mashup is the ultimate groveler. And the ultimate everyday board as well. Built in Helium Technology, it’s one of Firewire's absolute favorite boards for 2022.

Product Construction

Helium Technology
Ridden by everyone from Kellly Slater and Stuey Kennedy and Pacha Light. Each Helium shape is cut from the lightest foam blank in Firewire's stable – just .8 pounds, combined with a brand- new rail they crafted for Helium, using both Paulownia wood from thier TimberTek boards and balsa wood from Firewire's FST boards. It’s all wrapped in a brand new deckskin material we’re introducing for the first time. By pairing existing features from the highly successful FST (Future Shapes Technology) build process with an alternative sandwich skin material, Firewire has created Helium construction which uses this new composite in conjunction with a redesigned parabolic wood rail that includes both Balsa and Paulownia woods. The end result is that Helium has a 15% weight reduction over FST, a slightly faster flex and rebound characteristic, as well as a higher breakpoint. Lighter, stronger and more responsive... Helium is the future under your feet.
