Review: Osprey Rev 18 Hydration Pack

Osprey’s Rev series targets endurance runners who want to move quickly without having to worry about storage capacity. I purchased the Osprey Packs Rev 18 ($119.95) for my run commutes.  The Rev 18 is the second largest pack in the Rev series. All of the Rev series packs come in either Cirrus Grey, Flash Green, or Bolt Blue.

Rev Series:

  • Rev 24 – 24 liters/ ~ 1,500 cubic inches of storage
  • Rev 18 – 18 liters/ ~ 1,100 cubic inches of storage
  • Rev 12 – 12 liters/ ~ 700 cubic inches of storage
  • Rev 6 – 6 liters/ ~ 400 cubic inches of storage
  • Rev 1.5 – 2 liters/ ~ 100 cubic inches of storage
  • Rev Solo – 1 liter/ ~ 100 cubic inches of storage

The Osprey Packs Rev 18.

I selected the Rev 18 because of my storage requirements for my commute. 95% of the time the Rev 12 would have more than enough space for what I need but I wanted the extra storage just incase. I’ve worn the pack for more than 50 hours over 60 different runs.


I found it easy to get the Rev 18 adjusted for a comfortable fit. With the Bodybelt (Rev 6 and Rev 1.5 don’t have a Bodybelt) and 2 sternum straps the Rev 18 stays in place fully loaded or not. With a heavier load the pack will move side to side which can impair a normal arm swing. This can sometimes be avoided by repacking and placing heavier items at the bottom surrounded by with other items to reduced movement.

The 2.5 liter Hydraulics LT Reservoir has baffles inside the bladder that greatly reduce water sloshing while running. The pack has a plastic support in the hydration compartment and allows the water bladder to securely slide into place. The bladder’s quick release allows you to easily remove the it without removing the bite value and tube.  My only complaint is scuffing that occurs in the hydration compartment between the hydration cap and the material of the compartment. The scuffing doesn’t appear to be damaging the bag it looks bad.

The Osprey Packs Rev 18 has tons of storage. The pack has a huge main compartment separate from the hydration compartment. In addition to the main compartment the Rev 18 features a front panel with a bungee cord to keep your jacket strapped tightly to the bag.

The Bodybelt has left and right side zippered stretch mesh pockets. The right side pocket has a key hook to keep your keys in place on your run. Above the Bodybelt on either side of the pack are large stretch pockets that are perfect for quickly stashing gear.

The top of the Rev 18 has a zippered slash pocket for smaller items you might need to access quickly. The slash pocket is great because it allows you to store items without them falling down to the bottom of the main compartment. You can’t access the slash pocket without taking off the Rev 18. Fortunately the 2 zippered stretch mesh pockets on the Bodybelt give you quick access to items without removing the pack.

Osprey Rev 18 - DigiFlip

DigiFlip™ Media Pocket (with iPhone 5s)

The left side shoulder strap has the DigiFlip™ Media Pocket. The pocket can hold an iPhone 6 without a problem. The DigiFlip™ Media Pocket works well and I would use the pocket for runs longer than a few hours. But for my normal run commute it’s faster to store my phone in one of the Bodybelt stretch pocket.


My Rev 18 gets used 6 times a week and it can get funky. I’ve soaked the pack in a white vinegar solution to kill the odor and it works ok. During a particularly hot week I wash my pack in the washing machine. Machine washing worked really well. The Osprey care instructions say not to use a washing machine, so use caution if you try a washing machine.


  • Light –1 lb. 4 oz.
  • Durable – besides discoloring from rubbing no signs of wear
  • Storage – plenty of room to hold everything for ultras, 2.5 liters bladder
  • Secure – triple body straps keep everything tight to body


  • Accessibility – Must remove to access zippered slash pocket
  • DigiFlip™ Media Pocket – My iPhone 6 fits but it’s easier to access the phone in the Bodybelt pocket.
  • Cleaning – Can be hard to get odor out of the foam padding.

PRICE: 4/5
LOOKS: 5/5

TOTAL: 17/20
