The Molecule 50 is a hiking backpack from the brand Bach, featuring a modular construction that adapts to the gear you wish to bring on your hike. Certain parts of the Molecule 50, such as the lid, the hip belt pocket, the back panel, and the cords, can be quickly removed, allowing you to switch between a weight of just 740 g to 1,050 g fully equipped. The Molecule 50 is highly functional, with multiple attachment points for your poles, helmet, or ice axe, all in a model that is as lightweight as it is durable. Finally, its carrying system allows you to carry up to 18 kilos of gear, and its mesh ensures optimal ventilation, ideal for long hikes.
