Ultralight Backpack for Women
The Aspen is a backpack designed in Colorado (United States) by Symbiosis Gear, a brand founded by Sarah Berkeley with a clear mission: to create equipment that truly fits bodies with a chest. After years of hiking with backpacks that didn’t offer a comfortable fit, Sarah decided to design a backpack from scratch, thought of by and for women.
When to Use It
An ideal model for quick trips and multi-day routes where every gram counts. With a main volume of 38L plus 10L additional in external pockets (48L total), it offers enough space for essentials without encouraging overload.
The recommended load capacity is up to 9kg, perfect for those seeking lightness and comfort on medium and long distances. The ergonomic design (with S-shaped straps, 3-position sternum strap and foldable hip belt) reduces pressure on the chest and greatly improves stability, especially on descents.

Design
The “stealth” bottom pocket allows access to snacks or windbreakers without removing your backpack. The wide side pockets and zigzag compression keep the load stable. The roll-top sack closure makes it easy to compress the backpack to the volume of your gear as you go.
The 3-position sternum strap helps find the exact comfort point according to your anatomy, and the foldable hip belt provides support when you need it and disappears when you seek maximum freedom of movement.

Made of Extreema®
The Aspen is primarily constructed from a fabric called Extreema®, manufactured by EuroFibers, a Dutch company specializing in ultra-high-molecular-weight polyethylene fibers (UHMWPE).
This material stands out for being very resistant, lightweight, and durable, offering a strength-to-weight ratio superior to steel and ensuring exceptional performance. A great choice for this backpack!
