New 4FRNT SINISTER Pro Model Ski is Turning Heads

There's a new addition to the 4FRNT collection. The Sinister is the latest pro model from 4FRNT, and the first pro model for Norwegian Stinius Skjøtskift. As one of the most uniquely talented and well-rounded skiers on the planet, it's only fitting that Skjøtskift finally has a ski to match his style.

In recent years, the iconic brand has crafted beloved pro model planks with pro skiers Thayne Rich and Eric 'Hoji' Hjorleifson. Rich's ski, the Inthayne, is a true freeride ski that sits at 117mm underfoot, delivers generous rocker, minimal camber and rocks an aspen maple core with carbon stringers. It's on the more damp side compared to many soft powder offerings on the market, and lives for big landings and deep days in and out of the resort.

The aptly named Hoji is the mother of all pow-focused touring skis. It's heavily rockered in the tip with gradual rocker in the tail, no camber, boasts 112mm underfoot, floats like a dream and is built to easily maneuver the deepest snow on Earth.

The 2026 Sinister meets both the Inthayne and Hoji when it comes to deep snow performance, but it adds a little extra in terms of stability and pop. A ski like this makes a lot of sense if you watch Skjøtskift ski. He blends technical turns with impeccable airs, melting his hip over a roller and proceeding to throw a flawless cork 7. Trying to cater towards both specialties with one ski required some mad-scientist engineering, blending tip and mild tail rocker with a traditional camber profile, a Titanal "stomp zone" specifically-placed in the middle 3/5s of the ski, ruber inserts and an aspen maple core.

The 2026 4FRNT Sinister

Trying to create such a multifaceted ski isn't an overnight process. "This has been a two-year project from the birth of the concept all the way to the final version, which we just tested at [Mount] Hood in July," 4FRNT Marketing Coordinator and Team Manager Jake Doan told FREESKIER.

"Like Stinius, the ski is meant to charge and give back what you put in," he continued. "With nearly 70% of the core enforced with our Titanal stomp zone, the ski holds up incredibly well at speeds. The purpose of the tapered stomp zone is to maximize the pop and flex in the tip and tail, maximizing the energy of the aspen core."

This is 4FRNT's first major step back towards a cambered resort ski in years. "It's something we haven't touched on for a while, and Stinius had a major role in identifying this and addressing it," said Doan.

He continued, "One resort this ski would do well at is Alta... or similarly, Bridger Bowl, Jackson Hole - any resort that is steep, playful, with every type of terrain. I reference Alta, because my first day on them was after a 14-inch storm, and we were hitting all the classic airs off Wildcat. It felt really comfortable on big landings. My second day on them was three days post-storm hardpack, and they absolutely held up on chewed-up Highboy laps."

It's hard to pinpoint where the Sinister wouldn't excel

While the ski can toggle between pow and hard-packed well, Doan and the team emphasized that this isn't meant to replace the Hoji or the Nevar, one of 4FRNT's other recent endeavors built with camber. At 2330 grams in the 186cm length, this is a resort ski that can go out of bounds, but shouldn't be in contention for long climbs.

As intended by its creator, the Sinister can provide serious stability in the park. A more forgiving tip and tail, combined with the strategic Titanal delivers the support needed to stick bigger landings. And if you prefer a more bountiful swing weight when in the air, this is a great option. Plus, who wouldn't want to grab blunt on those flatter tails?

Skiers who push the speed limit in nontraditional ways and see ample deep snow throughout the season should strongly consider the Sinister for this upcoming winter. The eye-grabbing top sheet luered us in, but the semi-directional shapes and interesting core engineering have us hooked. The Sinister comes as damn close to a true 'charge everything' ski as we've seen.

Meet the latest addition to the 4FRNT line, The Sinister. Crafted by Stinius Skjotskift to meet the needs of skiers that don't fit into any one box of style. From laying over arcing turns in Norway, stepping up to the infamous British Columbia pillow stacks, and hunting down the deepest turns Japan has to offer, he drew inspiration from all types of skiing to create this 113mm underfoot freeride workhorse. Carefully blending camber underfoot with 4FRNT's tried and true rocker designs, he created a ski capable of an endless variety of condition types. As if this wasn't enough, he wrapped the lively Aspen Maple core with a Titanal Stomp Zone to guarantee every hit is a make. A ski so capable, it should be a sin.
