The renowned backpack manufacturer Bach Equipment is breaking new ground. With the Molecule 50 and the Quark 30, she has developed two lightweight backpacks for trekking and climbing. We have carried the two heavily weight-optimized models on tours several times. They are a successful mixture of the usual Bach wearing comfort, lightness and functionality.

Produced for four decades Creek Backpacks that literally go around the world. Bach Equipment is breaking new ground with the Molecule 50 trekking backpack and the Quark 30 hiking and climbing backpack. Spoiler: Even if the two lightweight backpacks are significantly lighter, you don't have to do without the usual carrying comfort. However, like so many other things, the back plate can be removed if you want to travel even lighter.

Bach Molecule 50: Perfect for multi-day tours

The 50-liter trekking backpack Molecule is the largest in Bach's lightweight series. It weighs 1100 grams but can be slimmed down to well under a kilogram for situations where every gram counts. And here we are with a central feature of the new Bach backpacks: These are modular so that they can be individually adapted to the characteristics of the planned tour.

Removable parts

With the Molecule 50, the lid (110 grams), hip belt pocket (25 grams), back plate (150 grams) and cords (3 à 15 grams) can be removed, resulting in a weight saving of 300 grams - more than a quarter of the total weight. But you will probably only do without the back plate in an emergency, as it is a central feature of the Bach backpacks and at the same time guarantees a high level of carrying comfort.

Diverse mounting options - expandable by 15 liters

What the attentive observer also notices are the missing compression straps. Bach relies on reflective paracord here, which, combined with the daisy chains distributed over the entire backpack, offers a variety of attachment options. Additional equipment such as a climbing rope, crampons, pickaxe or mats can be attached to the puristic single-chamber backpack.

These features and its size make the Bach Molecule 50 the perfect companion for multi-day tours. One important thing should be mentioned: the trekking backpack has a roll-top closure with a zip. This has the advantage that you can conjure up 15 liters of extra volume out of nothing.

Bach Quark 30: Lightweight climbing backpack

With a pack volume of 30 liters, the Quark is the smaller brother of the Molecule 50. At 870 grams, it is also a very light hiking and climbing backpack whose weight can also be reduced. It also shares central features such as the height-adjustable and removable lifting lid, the roll-top closure with zip or the two mesh side pockets with the largest model in the lightweight series.

The light Quark 30 can play its trump cards to the full on alpine activities.

With the three reflective cords, everything you need for a successful climbing or hiking day can be attached to the backpack. When it comes to the material, Bach uses robust yet very light nylon, which is additionally reinforced at critical points.

But Bach has not only remained true to the quality requirements with regard to the materials used. The backpack specialist also relies on the tried-and-tested PE back plate when it comes to carrying comfort – probably the most important element of a backpack.
