Spawned from the Broadcast series, the Hyperlite Gromcast is an easy-to-surf fun shape for all kids to enjoy. The wide profile provides needed surface area, but the Gromcast is short and easily maneuverable so kids can begin learning power carves and spins. Customize the ride with 3 removable fin options and relax on the cushy, comfy molded EVA traction pad.

Monocoque Construction
Integrating the top and bottom fiberglass layers into one generates a more durable board on side impacts to prevent delamination.

Layered Glass
With layered glass every Hyperlite deck will have the same pop off the double up year after year.

Biolite 3 Core
This core material is the gold standard in the industry and used throughout the Hyperlite line. Biolite 3 is their lightest and most durable formula to date.

Squash Tail Shape
A squarer back with rounded corners delivers a snappy feel with increased hold in the wave.

Molded EVA Traction
Ultra-grade EVA foam that's molded has a smoother finish and is considered more comfortable.

Rolled Edge Profile
A more rounded rail shape that suits beginners and intermediate surfers is great for your first surf session.

Wide Tail Profile
The wider the tail shape the more push you have down the wave with increased ollie power.

Dual Concave Base
Channeling water into two streams through the fins and out the tail allows for a fast and loose feel.
