The 4-LOCK™ Skin Integration System consists of an inconspicuous 12x9mm hole through the tail of the ski that we refer to as the Hoji Hole™ -named after Eric Hjorleifson. By inserting the self-locking skin strap through this hole, the skin becomes locked to the ski, eliminating tail clip slipping and skin failure forever. We worked closely with both Eric Hjorleifson and Pomoca skins for over 6 years of development to bring this system to life. Since its conception in 2021, we're proud to integrate this revolutionary system in all of Eric's skis

We took on this project with Eric for a very simple reason, the tail attachment system on pretty much every brand of skin out there can be extremely frustrating. They simply aren't working. The 4-LOCK system completely elimates tail clip slipping off your ski. Once we set out to tackle the project we uncovered a full list of inefficiences in other brands skin systems that we wanted to improve on.

Eric found that by placing the hole 20cm’s from the tail, he could reduce his skin length by up to 12% to improve uphill efficiency without effecting the skis downhill performance whatsoever. This reduced length brings the skin weight below 240g 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.
