Osprey has made a serious entry into the trail running pack game with their new Duro (men’s) and Dyna (women’s) packs. Available in 3 sizes each for both men and women, the packs come in 1.5 liter, 6 liter, and 15 liter capacity models. Something for every need, from quick runs with just some water and a rain jacket, to multi-day trail running tours, peak bagging, or fast packing trips.
We’ve been using all three sizes and have been providing them to friends for photos and testing. Overall the impression is very good, in fact Osprey has done something no other running pack has ever done for me, given me a pack that holds my camera and other gear together with no, as is in zero, bouncing around or stabbing me in the back.
These are not ultralight, ultra simple running packs, but they aren’t meant to be. They offer features for people seeking comfort & stability along with Osprey’s usual array of numerous pockets. If you are after super light race packs these are probably not for you. For example, the Duro 15L small pack, which is actually 13 liters, weighs 700 grams. In comparison, Salomon’s ubiquitous S-Lab ADV Skin 12 liter pack weighs 285 grams while Dynafit’s Enduro 12L is 289 grams. In my opinion, Osprey’s packs are perfect for general trail running, comfort, and will last forever.
Together with lots of our friends, we have been using them all summer in the Alps for everything from short & fast, to super long, and even The Way Up project. They have certainly been put to the test. The consensus? Super comfortable, super stable, but not what we’d do races in.
- Very well made, these aren’t going to fall apart anytime soon – bomber material and design.
- Hands down the most comfortable shoulder straps with much appreciated extra large pockets on the chest for soft water flasks and food.
- Stable, rock solid harness system. They simple don’t bounce or sway thanks to the shoulder strap design’s width and tensioning system.
- The option of using a water bladder inside the pack or only carrying soft flasks in the shoulder straps.
- Three sizes for three very different needs; 1.5L vest for minimalist days, a perfect 6L model for the “if you are just going to buy one, this is it” crowd, and a hefty 15L with a much appreciated waist belt addition for carrying heavier loads, more stability and extra waist belt pockets.
- The packs all come in a Small/Medium or a Medium/Large size to fine tune the fit.
- The sternum strap buckles are bulky and difficult to clip, especially with one hand. As a result of the type of clip, they are often joined at an angle causing the shoulder straps to pull unevenly.
- On the back of the pack is a compression sleeve/pocket that is great for shoving things into, but it has two buckles that work as compression/holding straps for the sleeve. The buckles cover the zippers for the main compartments and must be unclipped and re-clipped each time you access the pack. However, these are also the straps that provide for some extra stability and compression, so it’s a trade off…
- Lots of zippers and pockets – some may see this as a positive, for me a running pack should be a simple tube. I’d like to see the same packs with less zipper access pockets.
- Zippered pockets on mesh material. I’ve learned that mesh allows for sweat to move through it leaving salt behind once dry. Zippers can seize up from this salt so care must be taken to keep the zippers clean.
