Millet Prolighter 30+10L - The Expandable Alpine Backpack for Bigger Routes (1,000 g)

You're an hour above the car and the rope is already biting into one shoulder; the bivvy ledge is somewhere up in the dark, and the climbing doesn't even start until tomorrow. This is the outing that needs more than a summit pack and less than an expedition haul. The Millet Prolighter 30+10L is built for that middle ground: a 1,000-gram alpine pack that opens from 30 to 40 litres, carries skis, a rope and ice axes outside, and still climbs light when the difficulty kicks in.

The 10-litre extension collar is the whole argument for the pack: cinched flat it climbs like a 30, opened up it takes the layers, food and bivvy kit a multi-day route forces on you. Around it sit the tools of a real alpine sack - a side ski carry, a rope stash under the two-buckle flap, Millet's FPP™ ice-axe attachment, a hauling handle for the pitch you'd sooner haul the pack up than climb with it on your back, and a removable ergonomic hip belt you strip at the crux. You pack it to the route, not the route to the pack.

Where a rope and rack grind against it day after day, Millet armours the pack with tougher PA 1000D; everywhere else it runs the lighter PA 210D Honeycomb Robic ripstop over a Recycled PES 250D lining, water-repellent to 1,000 mm and at least 17 % recycled. Light where it can be, armoured where the route bites. It carries the name of a house building alpine packs in Annecy since 1921 - and when the collar or a strap finally wears through, Millet repairs it in its own workshop rather than selling you another.

What Makes the Real Difference on the Mountain

The Prolighter 30+10L is built around one idea - one pack that scales with the route - and gives you the alpine carry systems to back it up, all at a weight that keeps it climbable.

  • 🎒 30→40 L extension collar: compact for the climb, expandable for the approach and bivvy.
  • 🪶 1,000 g for 40 L: light for its capacity, no dead weight.
  • 🪢 Rope stash under the flap: held securely by the two-buckle closure.
  • ⛏️ FPP™ ice-axe + side ski carry: real tool attachments for alpine and ski lines.
  • 🧗 Hauling handle: built to be hauled up technical pitches.
  • 💧 Hydration compatible: bladder sleeve to drink without stopping.

The carry adapts to the day: a removable ergonomic hip belt and shoulder straps with load-lifter straps on belt and harness settle a full 40 litres on the walk in, then strip back when you want freedom of movement on the climb. A two-buckle removable flap opens the main compartment fast, with a zip pocket on the flap and one beneath it - the spot for a headtorch, a phone, the topo and the gels you don't want migrating to the bottom - and gear loops to rack what won't fit inside. Loaded for the walk-in it carries like a proper pack; cinched back to 30 litres with the belt stripped, it sits flat against your back and lets you climb.

Who This Backpack Is For

The Prolighter 30+10L is for climbers and ski mountaineers whose routes don't fit a single fixed volume - who need a pack that's compact on the climb and roomy on the approach, without carrying two bags.

  • You go multi-day in the mountains - bivvy routes, hut-to-hut alpine lines, ski traverses.
  • You carry a full alpine kit - rope, rack, ice axes, skis, with attachments that hold under load.
  • You want one adaptable volume - 30 litres cinched for the climb, 40 litres open for the walk in.
  • You still count grams - 1,000 g for a 40-litre technical pack with a strippable hip belt.

It's a specialist, so be clear on the use. There's no integrated rain cover and no panel-style access - for a do-everything 4-season pack with built-in weather protection and a suitcase opening, the UBIC 40L is the better all-rounder. And if your days are fast single ascents with a light kit, the smaller Prolighter 22L is all you need. But for committing alpine routes where the load changes between the approach and the crux, the Prolighter 30+10L is the pack that adapts. Part of the wider Millet backpack range we carry.

FAQ

+

The pack has a 10-litre extension collar under the flap. Cinched and buckled down, it's a compact 30-litre pack that climbs well; opened up and extended, it grows to 40 litres for the approach, the descent or a bivvy load. The two-buckle flap floats up and down to cover whatever height you've packed, so one pack covers both the climb and the carry-in without you owning two.

+

All three. It has a side ski carry, a dedicated rope stash held under the flap, and Millet's FPP™ ice-axe attachment for one or two tools, plus gear loops for racking. These are purpose-built alpine attachments designed to hold a real load on the approach and the climb, which is what separates the Prolighter from a general hiking pack.

+

Yes - that's the point of the Prolighter line. At 1,000 g for up to 40 litres with full ski, rope and ice-axe carry, it sits well below most touring or alpine packs of the same volume. The weight is kept down by the Robic ripstop main fabric, a minimal frame and a removable hip belt you can strip on technical ground - without dropping the reinforcements where a rope and rack grind against the pack.

+

It's a reinforced haul loop built to take the pack's weight when you sack-haul it up a technical pitch rather than climb with it on - common on harder alpine and big-wall routes. It also makes the pack easier to clip, hang at a belay or pull out of a crevasse - the kind of detail you only notice when it isn't there.

+

Same light-and-fast philosophy, different scope. The Prolighter 22L (630 g) is a fixed-volume pack for fast summer summit days and ski approaches. The Prolighter 30+10L (1,000 g) expands from 30 to 40 litres and adds a rope carry, a hauling handle and a more supportive belt for multi-day and committing routes. Pick the 22L for fast days, the 30+10L when the route carries more kit.

+

No - it's a stripped alpine pack, so there's no integrated rain cover. The fabrics carry a 1,000 mm rating and a durable DWR finish for snow and showers, but for sustained rain you'd add a separate cover or a dry liner inside. If a built-in rain cover and full weather features matter more than a technical climbing feature set, the UBIC 40L is the better-equipped all-rounder.

+

Empty the extension collar and every pocket, shake out the grit a multi-day route leaves behind, and let the pack dry fully before storing. Hand wash at no more than 40 °C with a mild soap, and avoid the tumble dryer, bleach, iron and dry cleaning that degrade the DWR. Re-proof the finish from time to time, and when the collar, a strap or a seam wears after hard seasons, Millet repairs it in its own workshop rather than replacing the pack.
