CarryIce axes, rope, skis

Millet · MIXT 25+5L

Rope, helmet, ice axes or skis: everything straps on the outside.

The Mixt 25+5 is a roll-top mountain bag that takes 5 litres more when the climb gets longer. It carries skis, ice axes, helmet or rope on the outside, and both the waist strap and the sternum strap come off to lighten it. The fabric, a PA 6.6 330D Mini Ripstop, is designed for snow and light showers.

What fits inside

25+5L

Five more litres unroll when the climb gets longer.

The roll-top unrolls to go from 25 to 30 litres, and closes with a quick clip. On the front, a zipped pocket and a mesh pocket keep the small kit; inside, a zipped mesh pocket takes the papers.

Millet

Millet, from Saint-Fons to Annecy.

Born near Lyon, in Annecy since 1929

In 1921, Marc and Hermance Millet sewed shopping bags and canvas sacks in a small grocery shop in Saint-Fons, near Lyon. The family settled in Annecy in 1929; in 1960 the sons turned to mountaineering backpacks.

Repairable, 2-year guarantee

Millet bags can be repaired in the Annecy workshop, which also looks after clothing, poles and sleeping bags. Millet guarantees its bags for 2 years; the 2-year legal guarantee goes through Eiken.

Materials chosen and tested

Millet picks its materials from those certified OEKO-TEX and bluesign, with no controversial chemicals, and tests them in its own laboratory before using them.

Eiken's take

Why we chose it: A climbing bag that changes volume and kit: 5 litres more, the rope, ice axes, helmet or skis outside, straps that come off to lighten it.
Worth knowing: It stops at 30 L: to go out for longer, the Prolighter 30+10 goes up to 40 L.
Who it's for: People who climb for the day with rope, helmet and ice axes, or go ski touring, and want a bag that lightens.

Baptiste, Eiken

Questions

How does the Mixt 25+5 handle rain?

The fabric is designed for snow and light showers, with no built-in cover. In rain that lasts, anything that must stay dry goes in a pouch.

Mixt 25+5 or Prolighter 30+10?

The Mixt 25+5 (610 g) goes from 25 to 30 litres; the Prolighter 30+10 (1,000 g) from 30 to 40 litres, with a haul loop.

What can you attach on the outside?

Skis on the side ski carry, ice axes in the FPP ice axe holder, the rope on the rope carry, the helmet, and poles in the pole holders.

How does the roll-top open?

It unrolls to open and closes with a quick clip; this system is what adds the 5 litres of expansion.

What does the guarantee cover?

The 2-year legal guarantee goes through Eiken. Millet also guarantees its bags for 2 years.
