Chamonix 15+5L – Modular, Durable Urban Backpack Built for Active Daily Life

The Chamonix 15+5L is a modular urban backpack designed to match the real rhythm of city life: work, commuting, cycling, coworking, long days that end late. Compact at 15 liters and expandable up to 20L thanks to its roll-top, it adapts to your needs without ever feeling bulky.

Made from 420D recycled nylon with TPU coating, it offers excellent resistance to abrasion and moisture. Light rain, urban splashes, daily commutes — its robust construction effectively protects your gear.

Designed for modern everyday use, it features a padded laptop compartment for devices up to 15”, a dedicated tablet sleeve, and smart internal organization to keep essentials within easy reach.

What Makes It Ideal for Everyday Mobility

• ✔️ Modular 15 → 20L Capacity – Adjust based on your day.
• ✔️ 15” Laptop Compartment – Dedicated padded protection.
• ✔️ Magnetic Roll-Top + Compression – Fast, secure closure.
• ✔️ 420D Recycled Nylon (TPU Coated) – Abrasion & moisture resistant.
• ✔️ Full Side Zip Access – Wide, practical opening.

The large side zip allows full access to the main compartment, like a compact urban suitcase. Under the flap, a zipped mesh pocket with integrated key clip keeps smaller essentials organized.

The thermoformed panel with crossed elastic cords — inspired by early Millet packs — adds both functional storage and distinctive outdoor heritage styling.
