The Best Vest Hydration Packs for Short to Medium Rides: Camelbak Chase vs. Osprey Duro

Camelback Chase 50oz Bike Vest vs. Osprey Duro 1.5 Hydration Pack

Choosing the best hydration pack for short to medium length bike rides can be a daunting task with so many great choices on the market. Whether you are looking for a pack for racing or rides, a 50oz option may be a good fit for your riding.

I’ve spent literally thousands of hours riding and racing endurance events around the world in the Camelbak Chase Bike Vest.  This year, I discovered the Osprey Duro 1.5 and wanted to see how it compared to the Camelbak.

Personally, the reason why these packs are attractive is because they are small, I can still access my rear jersey pockets, and I like to have the option to have a bottle on my bike with sports drink in it like GU Roctane for example.  I also like these packs because they don’t shift around on your back on bumpy or steep terrain and they breathe really well. The hip pack versus backpack choice is entirely personal.  I just prefer a backpack although Jenson has a number of great hip pack options.  I’m a professional endurance mountain biker, so I’ve spent a lot of time considering what the best set-up is for speed, function, fit, and durability when it comes to carrying a hydration pack.

factors to consider when choosing a hydration pack:

  • Water carrying capacity
  • Backpack vs. hip pack
  • Gear and tool storage
  • Material and fit
  • Easy access to food, tools, and phone on backpack straps
  • Ease of filling the bladder
  • Access to rear jersey pockets
  • Whether or not you will also carry a water bottle on your bike

Why 50 oz./ 1.5L?

For a 2-4 hour ride, the 50oz of water in the hydration pack plus the option of additional water bottle is more than enough.  In a race situation, it’s also nice to quickly be able to refill the water bottle at an aide station without having to deal the time penalty of refilling a hydration pack bladder.

Both packs come with a 50 oz bladder. The bladder straw can be moved to the right or left shoulder.  The attachment of the bite valve to the pack so the hose doesn't swing around is magnetic for the Osprey and hooks into a clasp for the Camelbak.  I preferred the Osprey system for securing the bite valve.

Both bladders are easy to fill.  The hose is easily detachable from the bladder. The Camelbak has a lid you unscrew and a handle to hold the bladder as you fill it.  The Osprey has a fold at the top and a plastic slide that secures the bladder.  You can’t go wrong with either bladder set up.

Gear and Tool Storage

The Camelbak Chase has a larger carrying capacity and more organization for gear than the Osprey Duro.  The Osprey Duro is really a minimalist pack.  For carrying capacity and organization, the Camelbak wins.  The Camelbak has an external pocket where you can carry a rain jacket, some knee pads, or even a small camera tripod.  There is also a zippered pocket on the back with space for things like a CO2, small first aid kit, multi-tool, tire levers, and snacks.  The Camelbak also has pockets on the front straps.  Their 2022 model claims that food and gear will not fall out, although previous versions are not as secure. 

The Osprey Duro does not have an external pocket for storing a jacket or additional bulky items, but it does have a small zippered pocket in the rear for your tools and food.  The Osprey has great secure storage on the front shoulder straps as well. 

For both packs, I put my small handpump (I use the Topeak Mountain TT) in the large pocket with the bladder.  Both packs also have extra small pockets for things like keys and the potential to hang a helmet off of them although there are better-suited packs if you’re schlepping a full-face helmet with you.

Material and Fit

Both packs are designed to mold to your body and with lightweight material. The Osprey has a light, breathable mesh that is uniform throughout the pack.  I didn’t encounter any issues with durability, but longer-term testing (and crashing) would be needed to further assess.  The Camelbak has thicker material, but has a mesh back that is breathable. The Camelbak has also been crash-tested by me and stands up to some abuse! 

Both packs are equally comfortable and don’t bounce around or throw you off balance on a steep descent.  The Camelbak offers women’s sizing with a different shoulder harness and also 2 body sizes. The Osprey comes in one size, and there is also a women’s version called the Dyna.  As a small female, I couldn’t tell the difference between the men’s and women’s Camelbaks and both the Osprey and Camelbak were comfortable and fit me well. Additionally, the packs both have easy on the bike adjustment so you can tighten the pack as you drink the water of your hydration bladder.

A Final Word

Basically, you’ll be happy with both of these packs.  If you plan to carry extra gear, the Camelbak Chase Vest is probably your best bet. If you want the lightest minimal pack, the Osprey is probably the one for you.  A quick sidenote is Camelbak also now offers a 70oz version of the Chase Vest. It’s bigger with even more gear organization and pockets, and you can still access your rear pockets.
