This Limited Edition Hoji features our new ground-breaking 4-LOCK™ skin system, which includes a pair of custom pre-cut Pomoca Free Pro 2.0 skins. Conceived in the backcountry by Eric ‘Hoji’ Hjorleifson, this is a first of its kind collaboration between 4FRNT x Pomoca x Hoji to create the lightest, most reliable, and easiest to use ski and skin system to date!
Our new 4-LOCK™ system consists of an inconspicuous 12x9mm hole through the tail of the ski that we refer to as the Hoji Hole™, named after Eric. By inserting the self-locking skin strap through this hole, the skin becomes locked to the ski, eliminating frustrating gear failure forever.
After years of testing, Eric found that by placing the hole in the rocker zone 20cm’s from the tail, he could reduce his skin length by up to 12% to improve uphill efficiency without affecting the skis downhill performance. This reduced skin length weighs in at less than 240g per skin and folds up impossibly compact, saving you more weight on your feet and more space in your pack than any other set up on the market.

HOJI 4-LOCK Construction
Ski Construction and Technology
Eliminating deflection, delamination and fractures in the ski tip. These three issues have long plagued the durability of freeride skis due to the abrupt change in snow conditions and tip slap on impact from catching air. The bordering material in a ski tip that joins the core end is most commonly comprised of hard, non-elastic polymers. We began experimentation in our White Room using different grades of Neoprene to withstand the shearing impacts and provide absorption for change in conditions. The result is a dampened feel that calms the ski feel and increases the durability.
We started with clear Aspen and Maple stringers running the length of the ski at min/max tolerance of the binding screw hole pattern. To reduce weight, we eliminated the Maple stringers, making the core 100% clear Aspen and then milling a 4mm x 60cm pocket where the min/max of the binding mount will occur and use clear Maple inserts to support the binding retention without adding all the weight. We rely on carbon stringers to support the tip/tail end of the core where the Maple is no longer present.
A non-elastic alternative to traditional fiberglass. The carbon runs the length of the ski like a stringer, acting as a springboard of flex, superior to what traditional fiberglass is capable of. Carbon Fiber adds an incredible amount of strength with very little added weight.
A complex insert which adjoins the core end and runs out to the tail edge perimeter. Full wrap metal edge skis often stood on their tail end have a tendency to delaminate, due the weak joint bearing the skis weight between metal, rubber and fiberglass. A tail block eliminates the sensitive joint between laminates and edge and allows for non-invasive customization for skin tail clips if so desired.
Semi Cap ABS Sidewall>
Similar to how you construct a sandwich, layers of premium raw material pile high into a 3D cavity that secures the shape outline with an ABS sidewall over edge. The semi cap design provides longevity and durability of the top sheet edge by stepping down from the square edge of the sidewall leaving a smooth 360 degree round-contoured edge perimeter. The exposed sidewall protects the core from moisture while also dampening vibrations.
Our premium ski base, also known in the industry as a “race base” because it integrates carbon to further strengthen its gliding properties. At 1.3mm this fast, freely gliding and tough carbon base is much more durable than other base material and matches perfectly with our 2mm edge material. The sintering process occurs prior to extrusion, where the the carbon and plastic enter into an extruder in pellet form, therefore individually contributing its own dense properties to the final product.
