MIXT 25+5L

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

+

25+5L: what does it really change in real-world use?

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.”

+

Is it truly suitable for ski touring?

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.

+

What about climbing or mountaineering: rope, helmet, ice axes?

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.

+

Is it resistant to rain? (1,000 mm, DWR…)

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.

+

Is it compatible with a hydration system?

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.

+

What load is comfortable with such a light pack (610 g)?

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.

+

How should I maintain it properly?

Hand wash at a maximum of 40°C with mild soap and air dry. Avoid tumble drying, bleach, ironing and dry cleaning.
