Prolighter 22L

Millet Prolighter 22L - The Lightweight Summer Alpinism Backpack (630 g)

You leave the hut in the dark, headlamp burning, the glacier going from black to blue as you gain height toward the ridge - and for the next few hours you want to think about the line above and nothing else. On a summit day every gram you carry up you carry back down, so the pack has to earn its place and then get out of the way. The Millet Prolighter 22L is built for exactly that: a 630-gram alpine day pack stripped to what a summer ascent actually needs, with ice-axe and ski carry, a frame that hugs your back, and not one buckle past what a summit day asks for.

Its whole design is in service of moving light and fast. A side ski carry and Millet's FPP™ ice-axe attachment hold your tools securely without flapping, a removable hip belt lets you ditch grams once the load is light, an extensible mesh side pocket and a front zip pocket keep skins, a bar or a topo within reach, and a hydration sleeve so you sip on the move instead of stopping on exposed ground. Narrow and close to the back, it stays out of the way on a scramble - which on exposed rock is exactly the point.

The fabric does the heavy lifting: a PA 210D Honeycomb Robic ripstop chosen for strength-to-weight, so 630 grams never means flimsy, reinforced with Recycled PES 600D over a Recycled PES 250D lining and water-repellent to 1,000 mm. At least 20 % recycled content by weight. The grams came out of the feature list, not the cloth - and behind the pack is a house that has built alpine kit in Annecy since 1921 and still repairs it in its own workshop. A light pack you keep, not one you replace.

Who This Backpack Is For

The Prolighter 22L is for people who count grams because they climb - summer alpinists, scramblers and ski mountaineers who want a pack that carries the tools and then gets out of the way.

• You move fast and light - summit days, glacier approaches, alpine scrambles, spring ski lines.
• You carry technical tools - ice axe, skis, a light rope, with attachments that actually hold them.
• You want a pack you forget you're wearing - narrow and close to the body, so it never swings out on a move.
• You value a clean design - simple access, the right pockets, a strippable hip belt, no dead weight.

It asks one honesty of you, though: this is a stripped pack. There's no integrated rain cover and no panel-style suitcase opening here - if you want a do-everything 4-season pack with built-in weather protection and big organized pockets, the UBIC 25L or UBIC 30L is the smarter buy. And if your alpine days run long or overnight, the bigger Prolighter 30+10L carries the same light-and-fast DNA with room to grow. But for a fast summer ascent where every gram counts, nothing gets out of your way like the Prolighter 22L. Part of the wider Millet backpack range we carry.
