Why We Like The Duro 15L Backpack

Instead of dealing with our gear annoyingly jostling around on our back, we focus on setting a new trail PR with the Osprey Packs Duro 15 Hydration Pack. Doing more with less, this true vest-pack provides bounce-free stability and utilitarian comfort as we log mile after mile.

The tough nylon design of this pack holds up against encounters with narrow slot canyons and snagging branches, while the hipbelt wrap with zippered pockets not only stabilizes the ride but also keeps the essentials right at our fingertips.


  • Lightweight, vest-pack for easy hydration when you're running
  • Ripstop face fabric fights off daily wear and tear on the trail
  • 2.5-liter reservoir with hose keeps you well-hydrated
  • Waistbelt adds stability and eliminates bouncing
  • Multiple pockets offer room for all of your trail essentials

Great for day hiking and trail running

I've put it through the wringer

I really like this pack for my 10-20mi long day hikes. Although a tight fit, I can pack the following in it; Grayl Geo Press 24oz, Solar power bank, Fido Pro Airlift sling for my service dog, first aid kit, sunscreen, bug spray, headlamp, plenty of protein bars, snacks for my service dog, she is a German Shepherd so quite a bit actually, collapsible water bowl, electrolytes pouches, 2 water bottles, iPhone 11 Pro Max, and car keys. Plus the included 2.5L water reservoir. It’s a lot to squeeze into a 15L pack, but it works. The fit is very comfortable. You barely notice it even when fully packed. The quality seems to be good. I have worn it several times now and I haven’t had any issues with on the Appalachian Trail. I highly recommend it.

Perfect trail running companion

I've put it through the wringer

I searched high and low for a pack/vest to use while trail running with my dog. Size is just right to pack bowls, food, extra layers, tools, and have plenty of water for the both of us. Hugs tight to the body in a comfortable way with minimal bounce. Durability has not been an issue. Highly recommended
