Why choose this modular backpack?

Minimum bulk for maximum capacity. This black bag offers an unbeatable space-to-capacity ratio: the expandable gusset creates no visible bulge. Weighing just 1 kg, it won’t overload your shoulders when hiking or commuting. Its robust construction supports loads of up to 8 kg without deformation.

Ingenious zip system: from 20 L to 30 L in a single movement

The zipper system allows you to quickly change from a 20 L to a 30 L capacity without putting the bag down. This precision-machined mechanism adjusts in a single second, ideal for adapting your bag to the duration of your trip or hike. The system remains accessible even when carrying the bag, for on-the-go adjustment.

Internal organization and storage pockets

• Front pocket: quick access to small items (phone, ID card, keys)
• Main pocket with gusset: Expandable from 20 L to 30 L, it can hold clothes, equipment or a laptop, depending on your needs.
• Velcro back pocket: closed by Velcro, secures valuables (wallet, passport) with easy rear access
• Molle system: turns your bag into a modular platform for adding external tactical pouches as required

Comfort and stability: an effective waist strap

This backpack is equipped with an adjustable ventral strap that stabilizes your load and frees up your hands. The bag’s light weight (1 kg) and ergonomic strap make it ideal for long journeys on hikes, in the mountains or in town. Even when loaded to 8 kg, it won’t distort your back thanks to its balanced construction.

Use cases and versatility

Mode 20 L: perfect for light day trips, urban travel or short hikes. Mode 30 L: deploy the gusset for two-night weekends, extended travel or technical expeditions. This bag adapts to your needs: outdoor activities, urban commuting, professional missions or DIY equipment.
