Petzl Crampons: The Full Lineup Compared

Petzl's crampon range is the most coherent in the industry: one family of frames, shared binding hardware (Flexlock straps, Leverlock levers), and a clean ladder from ultralight ski crampons to mono-point ice machines. That modularity is the reason we recommend Petzl so often — parts interchange, and you can often convert a crampon rather than replace it. Here's the whole ladder, lightest to most technical.

The coherence pays off after the purchase rather than during it. The steel models share the same tool-free linking bar and the same long-bar option for large boots, and the lever and cradle hardware is common across most of the range, so a replacement toe cradle, heel lever or strap is a part number rather than a project. ANTISNOW anti-balling plates come fitted front and rear on every model below rather than sold as an accessory.

The light end works on a second idea: the Leopard and Irvis Hybrid replace the steel linking bar with CORD-TEC Dyneema cord, so the crampon folds onto itself and packs small enough to carry on a day you are only half sure about. What Petzl does not do is hot-forge its points, so its steel files back to sharp quickly and rounds off faster on rock. The premium goes into refinement instead — snow shedding, strap hardware, and how well a lever holds adjustment across a season.

Weights are catalog figures for a pair and shift slightly with the binding version, because a strap cradle, a flexible toe cradle and a wire bail do not weigh the same. Each linked review carries the figure Petzl quotes for that model.

The bindings: Flexlock and Leverlock

Most Petzl models come in two versions. Flexlock = strap-on (C1), fits boots without welts. Leverlock Universel = heel lever with a convertible toe (strap basket or wire bail in the box), covering C2 and C3 boots with one purchase. If your boots have at least a heel welt, Leverlock Universel is the version to buy. Background: binding types and boot compatibility.

• Flexlock — strap-on, C1. Toe and heel cradles joined by webbing. No welts needed, but a genuinely stiff sole is. Offered on the Vasak, Irvis and Leopard.
• Leverlock Universel — C2 and C3. Spring heel lever plus a toe that takes either the flexible cradle or a wire bail, both supplied. Needs a heel welt.
• Leverlock Fil — fully automatic, C3. Wire toe bail with the heel lever, needing both welts. It is how the Dart is sold, the second version of the Sarken, and the LLF Leopard.

If you own more than one pair of boots, buy Leverlock Universel wherever a model offers it: one purchase fits both welt patterns. If none of your boots has a welt, your choices narrow to the Flexlock models — the Sarken, Lynx and Dart all use a heel lever, and a lever on a boot without a heel welt can be pulled off under load. That is a fit rule, not a preference.

How the range ladders

The models sit close enough together that the useful question is not which crampon but which rung. Read it from the bottom.

Leopard to Irvis Hybrid. Same 10-point layout and cord linking system; the Leopard is aluminum throughout at ~330 g, the Hybrid keeps a steel front section at ~540 g. Step up the moment the day might contain hard ice or a rocky col, because alloy points skate on water ice and round off permanently on rock.

Irvis Hybrid to Irvis. ~540 g becomes ~720 g and buys steel heels, a steel bar and no cord to inspect. Step up if the crampon spends the day on your feet rather than in your pack, or if you need a strap-on version.

Irvis to Vasak. The biggest step in the range, and the one most buyers should take. Ten points become twelve, and the extra pair are the secondaries behind the front points — the ones that support the boot when you tip forward onto your toes. Without them a 50° ice step is tiring and less secure.

Vasak to Sarken. Roughly 80 g and a front-point profile. Flat horizontal points become T-section, moving the working ceiling from short steps around 60° to sustained alpine ice around 70°. The Sarken has no strap-on version, so this rung is closed to B1 boots.

Sarken to Lynx. Fourteen points and a modular front section running mono or dual, each in two length positions, at ~1010 g. Step up when the ice is the route rather than the crux of an alpine day. Both toe attachments ship in the box, so one purchase covers B2 and B3.

Lynx to Dart. Sideways rather than up: ~800 g, a fixed mono point, an automatic binding and B3 boots only. Step across only if you already know you prefer mono and own a mountaineering crampon for everything else.

ANTISNOW plates and spare parts

Every model above ships with ANTISNOW plates fitted front and rear. Treat them as safety equipment: wet spring snow packs under a crampon into a smooth platform without announcing itself, and balling causes more unexpected slips than blunt points do. Tap the frame with the axe shaft whenever snow starts sticking, and replace plates that have cracked rather than running them.

The parts that need replacing over a decade are consumables — straps, plates, toe cradles and bails, and on the cord-linked models a length of CORD-TEC cord. Petzl sells them separately, which is what turns converting rather than replacing into something more than a slogan. On the Lynx the front points are replaceable too, which matters because a mono setup concentrates all the abrasion on one tip. Sharpen with a hand file following the original bevel, never a bench grinder — the heat draws the temper and the point never holds an edge again.

Which Petzl crampon for which person

• All-round mountaineer (most people): Vasak. Our overall best crampon of 2026.
• Steep alpine faces and couloirs: Sarken — T-section front points bite ice notably better for ~80 g.
• Waterfall ice and mixed: Lynx, dual or mono at will.
• Ski tourer: Irvis Hybrid; snow-only purists can drop to the Leopard.
• Summer glacier trekking: Irvis — full steel security, 10-point weight.

Who should buy a different brand

Winter trail walkers. If your season is packed snow, frozen forest track and the occasional icy traverse in flexible boots or trail shoes, nothing on this page belongs on your feet — points catch, the frame works against a bending sole, straps creep loose. Chain-and-spike traction devices are the right tool for that ground. Crampons begin where a slip would slide rather than stop, terrain that also asks for an ice axe you can self-arrest with and instruction before you rely on either.

Buyers measuring durability per unit of money. Petzl is rarely the cheapest route to a safe crampon, and Grivel hot-forges its points, which keeps the tip dense as it wears and holds an edge on rock longer. If your ground is more granite than ice, the Grivel lineup is the better fit; the direct head-to-head is Vasak vs G12 and the wider field is ranked in best crampons.
