7 Best Hydration Packs

1. Osprey Packs Escapist 32 Daypack - Best Overall

The Osprey Escapist Daypack is perfect for almost any outdoor activity. It features an external hydration sleeve for easy refills and its BioStretch harness and hip belt keep your load stable, no matter what terrain you’re trying to tackle. 

To make your life easier, this hydration pack also has an external pocket for sunglasses, as well as a helmet and blinker light attachment, making this pack absolutely perfect for cycling and mountain biking. 

It also has a front organization pocket for other random necessities and a stretchy mesh front pocket to conveniently stash a jacket or warm pull-over. Backpackers will appreciate the zippered divider pocket at the pack’s base that offers a dedicated space for dirty clothes or a light sleeping bag. 

Made of 100 percent nylon, the Osprey Escapist also has an integrated rain cover, making this pack ready to handle any type of weather.  

This pack comes in several bright colors and holds 32 ounces of fresh drinking water. However, the Osprey Escapist Daypack does not come with a bladder. You’ll have to buy one separately.

This is also a pretty sizable pack. Once you stuff it full of gear, it can be pretty hefty. We would like to see a metal frame on a pack this size, just to add some extra support.


  • External sleeve for easy refills.
  • BioStretch harness and hip belt for load stability.
  • Plenty of storage space.


  • Bladder not included.
  • Large size needs a metal support frame.

2. CamelBak HydroBak - Best Hydration Pack for Running

This fabulous minimalist hydration pack from CamelBak is a great choice for runners. The HydroBak has a narrow profile for maximum range of motion and reflective details to increase visibility on those early morning or late evening runs. 

The CamelBak HydroBak is lightweight and features an air mesh back panel for increased breathability and comfort on those hot, sweaty runs. 

The 1.5-liter reservoir is super easy to fill. You don’t even need to remove it from the pack. The only thing we would add to this highly functional hydration pack is a bit of insulation. With such a small reservoir, your water gets warm fast, and some added insulation would help keep your water refreshingly cool.


  • Lightweight.
  • Narrow profile is perfect for runners.
  • Reflective details.
  • Easy to fill. 


  • Lack of insulation allows water to heat up on hot days.

CamelBak goes the extra mile with this wintertime hydration pack, providing a Therminator  insulated sleeve to protect your water supply from freezing and a special storage compartment designed specifically for avalanche gear.
