MIXT 25+5L – The 4-Season Mountain Pack for Ski Touring, Alpine Climbing & Hiking (610 g)
You head out early, the cold front still biting, skis ready with skins on. The next day it’s a sharp ridge, rope and helmet clipped on. In summer, it’s a fast hike, a couloir to climb, a via ferrata to link up. The Millet MIXT 25+5L isn’t a pack for “just one activity” — it’s the mountain backpack you keep all year round, adapting without compromise.
Its key advantage: a 25L base volume with a +5L expandable extension, featuring a roll-top closure and quick compression system. Compact when moving light, more generous when the weather turns or your kit grows — extra layer, skins, down jacket or additional food.
At just 610 g, it stays incredibly mobile on ascents and fluid in movement. The N 100D ROBIC MIX ripstop fabric combined with a 1,000 mm DWR water resistance handles snow, light rain and early-morning moisture — so you can focus on the line ahead.
What Makes the Real Difference in the Mountains
The MIXT 25+5L isn’t built to be “okay at everything.” It combines alpine functionality, smart modularity and true on-terrain efficiency so you can keep moving — whatever the conditions.
- 🎿 Side ski carry – clean ski-to-boot transitions without compromise.
- 🧗 Rope & helmet carry – organized and secure alpine setup.
- 🪓 FPP™ ice axe holders – fast, secure attachment for light alpinism.
- 🔄 25L + 5L extension – adaptable volume depending on your objective.
- ⚡ Quick-access pockets – essentials within reach (phone, gloves, headlamp).
- 🪶 610 g – freedom of movement uphill and downhill.
Because the mountains are never predictable, its removable straps and compression system let you tune the pack structure to your load — lighter and stripped down when moving fast, more secure and stable when carrying extra gear.
Who This Pack Is For
The MIXT 25+5L is a true 4-season mountain backpack designed for those who want one pack that transitions between seasons without compromise — ski touring, light alpinism, climbing or technical hiking.
- You switch activities throughout the year — no need for multiple packs.
- You prefer moving light, but still need real carry options.
- You value efficiency — quick access, logical organization, smart modularity.
- You don’t tolerate unnecessary weight — only what matters.
If your main goal involves multi-day autonomy (heavy bivouac or travel setup), a 35L+ pack may be more appropriate. But for committed single-day mountain missions, the MIXT 25+5L hits the sweet spot: light on ascents, stable on traverses, structured when terrain gets technical.

FAQ
It gives you two packs in one: a compact 25L setup when you’re moving light, and an additional +5L margin when you add layers, skins, a down jacket or extra food. Extremely useful in the mountains where weather and effort often require “one more layer.”
Yes. It features a side ski carry system for bootpack sections, and a mountain-focused carry design. The format is ideal for day tours: water, skins, insulation layer, gloves, safety gear and food — without unnecessary volume.
Yes — that’s part of its DNA: rope holder, FPP™ ice axe attachments, and an organization system designed for action. It allows you to secure equipment externally without unbalancing the carry.
The fabric and lining offer 1,000 mm water resistance combined with a DWR (Durable Water Repellent) treatment. It handles light moisture, snow and short showers very well. For prolonged heavy rain, a rain cover or waterproof internal dry bags are recommended.
Yes. It includes a hydration sleeve, allowing you to stay hydrated without removing the pack while moving — ideal during active hiking, ascents or cold conditions.
It’s designed for a technical mountain day load: water, layers, safety kit and lightweight equipment. The waist strap, chest strap, load lifters and side compression system help stabilize the load and reduce movement on uneven terrain.
