Softech Zeppelin 2.0 - 3 FinExtra wide with loads of volume, these boards are incredibly stable for learners as they gain confidence riding small broken waves. The Zeppelin 2. 0 is the big rig of the Softech fleet. Wider, thicker with maximum volume and buoyancy, the Zeppelin is designed to be the most stable softboard on the market so heavier and entry level surfers can paddle onto and ride even the smallest of waves. Ideal for surf schools, wave pools and rental operations.
