Molecule 45L is our new lightweight and highly modular backpack for hiking, trekking or traveling. Considering how light it is, it is remarkably comfortable to carry. It is intended for more experienced users who are ready to switch to ultralight. With its modular compression straps and user-friendly features, this backpack is ready for anything – from a short weekend trip to a crosscontinental trek.

Waist-belt pockets and compression strap are completely removable.
Our Verdict
For ultralight backpackers seeking a pack that pulls out all the stops on features without weighing you down, the Bach Molecule 45 is a stellar choice. Tipping the scales at just over 1200 grams, this highly ventilated pack keeps the load close and stable thanks to its tensioned mesh back panel and contoured shoulder straps. Despite being featherlight, the Molecule doesn't skimp on versatility - the roll-top extends the main compartment capacity by 10 litres when you need to overstuff. Removable compression straps allow you to cinch down smaller loads.
Where the Molecule truly shines is its bevvy of thoughtful details that elevate it above essential ultralight packs. The stretchy side pockets are designed to securely hold bottles. The zippered waist belt pouches keep snacks accessible. A dedicated hydration sleeve makes carrying a reservoir clean and easy. For organisation, you get a shoulder pocket for your phone and a top pocket with a key clip. With its durable Cordura base, recycled ripstop nylon body, and feature-rich design, the Bach Molecule 45 is a top pick for ounce-counting hikers who still want excellent load control and livability on the trail.
