There’s not much to say about this aside from the massive amount of space.
The back panel includes three raised areas as part of Camelbak’s “Integrated Ventilation” system. I did not think I was going to like the running feel of this at first, as most packs that include ribbed or raised areas tend to slightly rub my back or are just generally downright uncomfortable. However, I was very surprised that the system is not only comfortable, but the ventilation system works much better than another favorite design of mine – Osprey Packs Airspeed system.
The shoulder straps are generally unremarkable. In addition to the standard lower buckles used to tighten the pack against your body, there are upper buckles as well, to change the top angle of strap to better fit on your shoulders. The straps are fastened together horizontally with a single sternum strap, and once everything is cinched down and tight, the pack is tight and comfortable to wear.
The waist band is wide and almost entirely padded, save for the area where the buckles fasten together. On the right side, there is a small, zippered pouch. It’s not quite large enough to hold a phone, but is perfect for a wallet or a set of keys. On the run, the waist straps tended to loosen and I had to re-tighten them every 10 minutes or so. The waist band was quite comfortable overall, and created no noticeable chafe or irritation on the run.
The Fourteener comes with a sizable 3-liter reservoir. The entire system is pretty standard, with tube holders on the shoulder straps and a bite-valve mouthpiece. The bladder is quick to open and easy to fill.
This bag is probably overkill for most run commuters, but it really is fantastic. I prefer the Camelbak Fourteener over my all-time favorite Osprey Rev (discontinued) and another great – the Osprey Manta. The carrying capacity is insane, and I have lost items inside this pack more than once, only to find them again days later at the bottom of the front pouch. The additional space is perfect for those fall/winter transition days where the morning is perfectly comfortable for running in tights and a short sleeve shirt, but the afternoon lunch break or transit ride home requires a heavy winter jacket. Or, you decide to pick up a bag of groceries on the way home. Don’t worry – they’ll fit.
