Burton Mystery Skeleton Key 2021

Size Chart
- +


The 2021 Burton Mystery Skeleton Key is the culmination of all of Burtons resources coming together to make the best board possible, injected into one of their most popular board shapes. It floats in powder without breaking a sweat, carves the groomers with pinpoint precision, and can even handle the park. Featuring their lightest ever core, their fastest ever base, and confidential Mystery construction, we're pretty sure some of the materials in this board shouldn't even exist yet, but here they are all coming together to make one of the lightest, most powerful, and highest performing snowboards ever conceived. Poppy directional camber keeps the power underfoot while keeping the nose above the surface, and the unique lightweight design rides well and turns heads. The Skeleton Key is a board we can't get enough of, so get in quick or you'll miss out. 

Key Features

Skill Level: Intermediate / Expert

Board Type: All Mountain

Camber Type: Directional Camber

The original, tried and true camber type, and the advocate of powerful turns and poppy precision. Traditional camber is the most aggressive camber type, offering unmatched power, response, and edge control. Directional Camber puts rocker in the nose of the board, adding extra float in powder while retaining the response and stability of traditional camber.

Flex: 4.5/10 (1 = soft, 10 = stiff)

Directional Flex - This board is constructed differently from nose to tail, putting more pop in the tail and strengthening the nose, allowing you to easily maintain control and charge through a variety of snow conditions.

Shape: Freeride Directional

This board has a shape designed specifically for freeriding, featuring a longer, wider nose and a shorter, tapered tail which combine to give you effortless float in powder and better performance riding forwards.


Dragonfly II 500G - This is Burtons lightest ever core, which integrates carbon laminations inside the core which provides ultimate pop and performance with minimal materials.

Multizone EGD - The wood grain of the core is positioned along the heel and toe edge in four separate zones adjacent to the channel, channeling power from the source directly to the edges for ultimate strength and edge control.

Mystery Glass - Burton are keeping this one confidential, but just be sure this is some feather-light, robotic-built, space age tech that simultaneously improves power and response.

Squeezebox - Squeezebox consists of thicker, more powerful sections combined with thinner, more flexible sections profiled throughout the core. This enhances energy transfer and makes the board snappier and more stable

Base: Methlon

Incredibly durable and low-maintenance, the Methlon base is the highest grade sintered base available from Burton, providing flat-out speed that lasts.

Mounting System: The Channel

The Burton Channel system forgoes your traditional 4-screw mounting system and introduces a channel for your front and rear inserts. This allows you to fine-tune your stance width, and gives you more freedom in your stance location. The Channel is compatible with most major binding brands, but works best with Burton EST bindings. 

Additional Features:

Infinite Ride - Burton is able to maximise pop and performance by overbuilding their boards in the factory, and then using machinery to break it down for you. This allows your board to ride the same from day one, to day 100, season after season.

Pro Tip - The tip and tail of this board taper out at the points, reducing swing weight and promoting mobility.

Super Sap Epoxy - Super Sap is a bio-based resin that reduces the carbon footprint by 50% over conventional petroleum-based epoxies.

Balanced Freeride Geometry - A setback camber and stance-centred sidecut makes this board feel like a twin when riding flat based, but still has the tight turns and effortless float you'd expect from a directional board.
