The ultimate all-conditions pack for fast hikers and mountain runners. Stable and secure with a body-hugging harness, water resistant fabric, taped seams, and volume for long distance tests of endurance.

Rab says:

The Aeon Ultra 20 is the ideal day pack for committed mountain runs and fast hiking adventures in all weather, with enough volume for a summer bivi or bothy overnight. Built with tough, water-resistant fabric, taped seams and roll top closure, the Aeon Ultra seals out the elements, for those who get out and get it done. On-harness walking pole attachment and stretch side stash pocket enable quick access to kit for adapting to oncoming terrain or variable conditions. Hydration compatible with space for a 3L bladder with multiple harness pockets for storing snacks, gels, or flasks, you can stay refreshed without needing to stop.

Moving with you, the responsive and flexible Air Contour™ back system keeps the air flowing on intense ascents. Close-fitting and body contouring, the double strap harness and moulded back panel provide a comfortable, secure, bounce-free carry. Designed with a lightweight cord compression system, the Aeon Ultra keeps the contents of your pack secure. Completed with a pull forward, dual action harness cinch, the Aeon Ultra provides excellent stability at higher speeds, ideal for clocking miles over rugged ground.

Our Verdict

Built primarily with runners in mind, this is a very versatile pack, that has managed to cram a lot into the pack’s 28l capacity. It’s been designed, with the intention of never having to take the bag off, until you either finish your trail, stop for lunch or camp. Multiple storage pockets and user-friendly features mean everything not stored in the main body of the bag, is accessible to you at all times without the need to stop.

If you drink from a water bottle, 2 large mesh side pockets are provided, both of which are easily accessible while the bag is on. If you’re a bladder user, a cavity capable of housing a 3l bladder is located next to your back, or if you prefer soft water bottles, 2 pockets have been provided on the shoulder straps. This is what I mean when I say the bag is very versatile, it suits a lot of running and hiking styles.

Fully tape seams and a roll-top closure, ensure the Aeon Ultra seals out the weather, protecting your gear inside the 28l space. A large rear mesh pocket swallows wet weather gear/things you want close at hand. The large, highly breathable shoulder straps have pockets on each strap for mobile phone, water bottles, GPS devices, keys, etc. 2 hip belt pockets provide additional storage, perfect for energy bars. 2 walking poles can also be stored, again without having to take the bag off. All poles will fit, but z-poles fit the snuggest, keeping the pack streamlined.
