Product Description

Derived from the more refined Slipstream of the past, the new 7S Jetstream is a true hybrid surfboard, both from a design perspective and by definition of its performance. Now with more volume under the chest for better paddling and overall usability, this ‘Performance All-Rounder’ will adapt to a range of conditions from mushy beach breaks to classic point waves.

OUTLINE: There’s more surface area up front compared to a regular shortboard, which is great for generating speed and acceleration when driving off your front foot. The back half resembles a traditional shortboard with a refined outline and a forgiving round tail for smooth, yet controlled rail transitions.

CONTOURS: Tried and tested around the global, the subtle single-to-double concave with vee out through the tail delivers a balance of speed and flow over flatter sections, and responsiveness in hollow waves.

ROCKER: Low-to-moderate entry rocker is designed to offer immediate acceleration from the take off, but still allow the board to fit into more critical parts of the wave. The relaxed tail rocker helps maintain down the line speed, and creates acceleration through the entire turning arc.

FOIL: Foiled just enough through the nose and tail so the board delivers a nice feeling of sensitivity. The performance rail profile completes the design package by adding a highly responsive feel when the board is carving on rail.

PERFORMANCE: Regarded as the most user-friendly hybrid model on the market, the 7S Jetstream is essentially design to make performance surfing a little easier, and create a better approach to the way you ride waves.


NOTE: rider weight is based on board volume and intermediate rider skill level.

Technical Info


Innegra Matrix

Created in collaboration with Colan Australia, Innegra Matrix (IM) is an exciting new material that’s exclusive to GSI and the 7S board range. IM consists of 3oz bi-axial fiberglass orientated at +/- 45 degrees, an Innegra cross-net woven through the fiberglass, plus 13 unidirectional carbon strands, all of which forms a single layer of fabric that's laminated on the bottom of the board. The deck lay-up has a quad-axial configuration of fiberglass at +/- 45 degrees & standard 4oz fiberglass at 0/90 degrees. With this build, we also use a high density EPS core tha’s cut and finish shaped, and a special ultra bright epoxy resin. Overall this construction helps to control the boards torsional flex (twisting), while the carbon strands control the longitudinal flex. As a result, we still achieve that ‘pop’ and ‘lively’ feel from the EPS core, but with an underlying feeling of control and dampening that’s closer to a traditional PU board. Less chatter, more dampening = smoother through turns.
