Locals thrive on active lifestyles, whether it’s rock climbing, paddleboarding, or hiking Chautauqua Park and shopping at the Farmers’ Market. Boulder is all about outdoor fun and having a trusty backpack for all these adventures is essential. That’s where the Rab Aeon 20L comes in, and let me tell you, it’s been a game-changer.

The Rab Aeon 20L is Boulder, CO approved. It’s the ideal companion for your outdoor escapades in this adventure-packed city.



  • Despite its compact 20 L size, this pack has numerous advanced technical features for a range of activities. 


  • The hip belt is slightly longer than desired–mostly due to my smaller size–the storage in the hip pockets compensate for this.

Living in Boulder requires a “plan ahead and prepare” mindset. This involves proactively organizing my gear to ensure I can participate in any activities that may come my way. That’s a tall order to expect from a day pack–but yall I think we found it. With unpredictable days, having a to-go pack with all the essentials is an absolute necessity. I was stoked to get my hands on the Rab Aeon 20L for this very reason. This is a pack that can go from the office to the climbing gym and then out to a brewery–I have truly enjoyed my adventures with the Aeon.


The Air Contour X™ carry system is a game-changer. The Aeon molds to your body with adjustable features like the chest strap, hip belt, shoulder straps, and back length velcro. It is incredibly comfy and lightweight. Plus, the back panel’s mesh keeps you cool, whether you’re trekking diverse terrain or making dynamic moves.


The Aeon is purpose-built for adventure. It has two TipGripper walking pole attachments, a walking ax loop, and adjustable straps for all torso sizes. My personal favorite? The three easily accessible stretch pockets – perfect for water bottles, rain gear, and cameras. The zippered hip belt pockets are handy for keeping snacks, phones, sunscreen, you name it! And with an included rain cover and a dedicated H2O compartment for a 2L bladder, it’s ready for any weather or hydration need.


This day pack blends fashion and functionality seamlessly. Whether you’re a townie or an outdoor enthusiast, its sleek design appeals to all. It’s not just about looks, though. The Aeon combines fashion with technical skills, featuring weather-resistant coatings, robust stitching, and adjustable straps for supreme comfort and support. It’s a day pack that says, “I look good, but I’ve got your back.” As we all know: rule #1 look good, rule #2 safety.

Made from high-quality materials, including 50% recycled 70D x 140D Nylon DOBBY and Trishield abrasion and tear-resistant fabric, this pack is built to last. Plus, it’s hydration-compatible, so a 2L bladder is a great choice. You can easily attach any trekking poles to the straps.
