    Simple and Uncomplicated

    • Familiarity: I've used it several times

    Love this pack for trail running. I have had this pack out on both trail runs and road runs so far this season and been impressed. The pack is simple and has just enough pockets so that you will have everything accessible but not lose everything in hidden pockets. I particularly love the multiple chest pockets. I am 5ft 10in and weight 150lbs. I generally wear a medium in Arc'teryx shirts/jackets and the medium/large fits perfect. It does get warm on the back panels but it is to be expected. Overall, love it and highly suggest it.

    Simple and Uncomplicated

    Just the right amount

    • Familiarity: I've used it several times

    The osprey duro provides just enough space for a lot of variability. A 1.5 liter hydration res has been just the right amount of water for my dog and I on 15 or so mile trail runs. The organizational components of the duro 6 are great, I store energy gels in the small pockets on the straps and a layer or two if needed in the main compartment. I received this pack as a gift but would really recommend the grey color for summer, and the black has me sweating almost instantly. Maybe in the future a little more breathability in the fabric would be great. Overall I am super happy with this hydration vest and would really recommend it to a new runner for the ease of organization and durability of the product.

    Just the right amount

    Lots of features in a small pack

    • Familiarity: I've used it several times

    I love the pockets and zippers this pack has to accommodate cell phones, rain jacket etc. The hydration bladder has come a long way and makes for an excellent system. Only request to Osprey would be to make one size bigger than the M/L

    Very impressed so far

      I bought this pack to use trailrunning. I haven't been able to hit the trails with it yet, but I've taken it on a quick 6 mile run while pushing my two kids in a stroller. As with every other osprey product I've purchased in the past, this pack does not disappoint. Osprey thinks of everything. I can't wait to actually test this out on a long trail run.

      21 miler with my Desert ready Duro

      Rear view of the Duro. There's not many things I'd change on this great pack, though one is the outside pouch buckles. I would have them placed lower, not covering the zips. The outside pouch material is nice and stretchy, making it easy to store your rain/wind layer for quick access.

      The Duro feels like many other well made running packs I've used. An extension of the body. No bounce felt while winding along single track trails in the desert.

      I went down to San Rafael Swell with the Duro 6 this last weekend. I put in around 40 miles with it so I have some good input on what I think about it.

      Favorite Features - I was questioning the chest straps at first because it's a design I've never used before, but find them to be easy to connect and remove while on the move. The snap closure "click" is satisfying and nice to know it's locked down without looking. Osprey is the first brand I know of to do this instead of a buckle.

      I personally use my phone for GPS routes and photos often on runs so it's nice to have the front zip pocket to put it in. I have an S7 (good size phone) and it fits great! This gives quick and easy access to my phone and security knowing it won't fall out of an open pocket.

      I love how it comes with its own hydration bladder, but if you prefer using soft bottles up front that's a perfect option too. I personally want more room in my pack for snacks and a rain jacket, so I removed the bladder.

      The pack feels super light, well designed and very durable. On my 20mi run through the desert it felt like an extension of my body, which shows Osprey put some good thought into this running pack. It didn't move around, bounce, or chafe my body whatsoever!

      I recommend this pack (6 liter version) to anyone who plans to be on the trails for 1-8 hours at a time, such as a trail 5k up to 50k is perfect. There's enough room for about two liters of water, estimate of 2,000 calories of food, rain layer, gloves, phone, and some extra space for other small essentials.

      One thing I don't care for is the double buckle closure on the back. Visually it looks like Osprey went for something similar to a mountain biking pouch to hold your helmet but smaller. The buckles close over the zips. I feel having the buckles lower and not covering up all the zips would make access easier while I'm on the move.

      I'll send another update after I put in around 500 miles in the pack! Stay tuned.

      Great Fall/Spring/Winter, Awful Summer

      • Familiarity: I've used it several times

      39.5-40" chest, S/M

      I ordered the S/M and M/L in this, plus the M/L Salomon ADV Skin 5, and ended up keeping the S/M Duro which says a lot because hydration vests are Salomon's wheelhouse. If you don't want to watch the sizing video, 34-40 is S/M, and 39-45 is M/L. I'm right in the middle, but opted for the smaller size because a vest like this should be snug.

      The Good:
      I really like the overall design and materials. The squishy mesh inner doesn't chafe at all, and you could probably go shirtless. The pocket selection is solid and the compression straps on the back keep everything locked-down. I run with my dog, so I carry his leash in the big pocket, poop bags in one kangaroo pocket, and a 1/2 cup measuring cup for him to drink out of in the other, plus my phone, buff, and a gel in the front with room to spare. The main reasons I kept the Duro are the excellent bladder integration (easy removal/refilling) and the stiff plastic strips on the front for the straps. They provide the perfect amount of structure and prevent one side of the vest from being higher than the other. Seriously. So nice having everything lined up without having to think about it.

      The Bad:
      Fit is subjective, but I think Osprey could do a better job here. Only offering two sizes in a running vest seems crazy. Ultimate Direction has 3, Salomon has 4 in their Advanced line, and a whopping 5 in the S-lab. If Osprey added two more sizes, they could ditch the side compression, extend the rear kangaroo and front mesh pockets, and really dial in the fit. Check out the Salomon vest for what I mean.

      Update: This is unusable for me in warm, humid environments. The heavy nylon is great for keeping a drizzle out or adding some extra core warmth, but it kills the breathability. I ended up soaking everything I was wearing on multiple occasions and had to switch to a waist belt because I couldn't afford blisters while training for a 50k.
