ClosureMagnetic roll-top

Millet · Chamonix 25+5L

A 16-inch laptop on your back, and a profile that stays slim.

The Chamonix 25+5 closes with a magnetic roll-top that takes the volume from 25 to 30 litres when you need it, and also opens by a zip on the side. The laptop has its own protected compartment, the tablet too. The fabric, a recycled nylon coated with TPU, copes with light rain and everyday use.

Laptop

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: This is the bag for the commute by bike or on foot with a 16-inch laptop: a magnetic roll-top, a slim profile, a fabric that takes light rain.
Worth knowing: At 25 L and 850 g, it is a city bag, not a mountain one: to carry a load on a trail, look at the Parmelan instead.
Who it's for: People who ride or walk to the office with a 16-inch laptop, and go to the gym afterwards.

Baptiste, Eiken
