Crush races and trail workouts with this lightweight pack.

Stay hydrated while you're crushing trail races or daily workouts with the super light and streamlined Osprey Rev 1.5 Hydration Pack. Osprey entered the ultralight game this year with its Rev series, and the Rev 1.5 is the smallest of the lot. The backpack comes with an integrated, lightweight 1.5-liter reservoir that's specially designed to prevent water from sloshing around while you're bouncing up and down the trail, and the backpack itself is designed to fit snugly and follow your movements to prevent irritating jiggling and uncomfortable chafing.

Not just one, but two sternum straps keep the pack securely in place, and can be adjusted to your preferred position. One includes a magnet that conveniently holds the drinking tube's bite valve so you can quickly sip and then get the drinking tube out of the way. Two pockets—one on each shoulder strap—hold energy gels and your cell phone. The Rev 1.5 is designed to sit higher on your back, and it doesn't use a hip belt since the shoulder harness supports the weight of the pack. With the Rev 1.5 on your back, you won't ever have to worry about your hydration pack slowing you down during a race or fast-moving training session.

Eh...

  • Familiarity: I've used it several times

I was sold this backpack as a running backpack. I was hoping to use it for really long runs during the summer. It's great for hiking but when I ran with it I chaffed REALLY bad on my lower back. It also rubs in my armpits weird. I do like the magnetic piece for the drink tube, that part is really convenient. The storage is nice too. I can fit the bladder, food, my phone, keys and my houdini jacket in it. It's tight, but I can do it. I wouldn't recommend it to a friend... Especially a female because the fit doesn't seem to be made for women.

Eh...

Hi Jordan, this pack has posed challenges for us on fit because it's supposed to fit more like a vest. It does fit many bodies, but not all. The good news is that we have been working on a replacement, designed for men and and designed for women. Thanks for the review -

  • Familiarity: I've put it through the wringer

Love this pack. Perfect amount.

Pros:
• Clear holder for phone on the front left strap. This is really nice for easy access to your phone to see the time, pull it out and take a picture, or storage if you don’t have space in the rest of the pack.
• Small mesh pocket in front of the phone pocket. Love this feature for putting extra energy bars, a knife
• Elastics on the front can hold a flannel or light weight jacket nice and snug while hiking/running.
• Easy in and out access to the water bladder.
• Magnetic attachment for the straw.
• Love how this pack just has chest straps, rather than a chest and a waist strap. Makes for a well fitted pack, and less chaffing.
Cons:
• Anything longer than 10 miles chafes your back. This thing did give me a blister on my back. I tightened it down pretty snug to reduce any extra friction, but still got a blister on my back from the strap. But as to be expected when running long distances.
• Space is limited. But this is great for reducing weight.
• The Magnet does come loose and the straw comes off while running downhill sometimes.
