SIMS' Unidentified Aerial Phenomena is inspired by the Sims Shaun Palmer UFO pro-model with an identical base graphic, and a top sheet created as an ode to Palmer’s Joker. Despite being a surfy long nose twin, the tip and tail widths are are actually the same which allows you to ride freestyle in all directions, plus they are reinforced with a Dual X Carbon layup and feature flexible Thin Tip Tech for reduced swing weight.

MOD 4 Core - A unique blend of poplar, bamboo and paulownia wood in a balanced array, make this Core lighter, provide increased repulsion, increased strength and a lively feel.


Dual X Carbon Layup - Two X profile carbon layers underfoot reaching out into the tip and tail provide evolved pop, stability, and efficient power transmission edge to edge, making this construction one of SIMS's most versatile and responsive anywhere on the mountain.

Tri-Tex Fiberglass Laminate - This is SIMS' most advanced matrix; a 3-way lay up that combines light fiberglass at 0°, 45°, and 90° degrees, ensuring unquestionable pop, rebound, flex, and torsion in the highest performance boards.

Flexible Thin Tip - This weight-saving technology reduces material in the board’s tip and tail, resulting in lighter swing weight which makes it easier and faster to spin and rotate tricks.


Premium Racing Base - Utilizing industry leading technology from ISOSPORT, this high-density, high-speed base material is chosen for its molecular weight, which delivers unrivaled speed, excellent wear resistance, and increased wax permeability.
