Meet the Harpoon™
Cutting-edge technology for the backcountry.
A portable, lightweight, 2 person ski lift you can set up and take down the same day, in minutes.
Lifts 2 big riders for 1500m-2500m on a single charge over 55 degree incline.
Aerospace grade aluminum (7075AL), Dyneema™ rope, and a mighty 4500w motor.
We made ZERO compromise while designing and engineering the Harpoon™. Because when you're deep in the backcountry, things just need to work. Period.
We had always dreamed of a backcountry ski-lift that's lightweight, can be setup and taken down in minutes and would lift 2 skiers all day long.
After 3 years of development and 4 prototypes, meet the Harpoon™.
A self-tailing winch coupled to the electronics and motorisation of an ultra-high performance electric skateboard. The result is engineering insanity and nervous giggles of excitement all the way up.
It's capable of hauling 2 heavy sk(r)iders for 1500m up the steepest line or 3000m up a green run at your local resort on a single battery charge. The battery is easily hot swappable in the field (extra battery sold separately).
The Dyneema® Fiber rope (UHMWPE) has a polyester sleeve for high abrasion resistance. It yields the maximum in strength-to-weight ratio and is stronger than wire cable constructions. It's 1/7 the weight of a wire cable of the same strength, i.e. a cable of the same strength as the 10 lbs Harpoon rope weighs 70 lbs.
The Dyneema® rope floats, offers superior flexibility and stands up well to intensive use. The specific 4mm rope we use has an average strength of 1000lbs and our original ropes have held up very well in the 3 winters of tests they have endured.
The Harpoon™ system was engineered for 2 riders and has been designed so each rider never carries more than 10lbs of Harpoon™-related equipment in its backpack at any given time. The battery and Harpoon™ can be easily disconnected so when riding down, their total weight can be split through both rider's backpacks.
After building a dozen different battery packs, we finally settled on a 54 cells configuration that fits perfectly in the 904 Nanuk waterproof and shockproof case. This chosen configuration provides the lightest weight (the objective was 10.5lbs max) while packing the biggest punch. The electronic speed controller we use is the Lacroix Stormcore 100Dx which was developed internally. It's tried and tested as we have been using it for 3 years in high performance electric skateboards. Oh, and we included a USB charging port for your phone on the battery as well.
- Harpoon™ self tailing winch; 6.4lbs.
- Battery (made of top-shelf Molicel P42A cells); 10.4lbs
- 500 meters of Dyneema™ rope (including spool); 10.2 lbs.
A single skier can climb up to 5000m of vertical on a single charge, while 2 skiers will climb
The Harpoon™ has a towing capacity of 800lbs and the 4mm Dyneema™ rope has a 1000lbs strength (less 20% at the knots).
Its maximum cruise speed is 4.2kmh (1.2 meters per second), making it the fastest, strongest and lightest portable lift.
Imagined, tested, designed, and manufactured in the Laurentians, i.e. ski-country 1h outside Montreal, Canada.
- Harpoon™ high-powered motorized winch
- Battery pack & Stormcore 100Dx ESC
- 500 meters of 4mm Dyneema® rope on a lightweight polymer spool
- 2 belay seats
- 12 Black Diamond Litewire carabiners
Get unstuck
As a powerful, lightweight 800lbs mini-winch, the Harpoon™ comes in handy to pull you out of any sticky situation.
A new way to reach the hard-to-reach
The Harpoon™ is the most powerful lightweight mountain tool.

Our Story
Deep powder has always been the inspiration for everything we do. We try to emulate it (as our CEO here in NYC), but nothing will ever beat it.
