Osprey  Duro Pro 10 Hydration Vest

[This review was collected as part of a promotion.] Sadly had to return I have had a duro 15 for many years but needed replaced The 10 is just too small to fit my mandatory kit comfortably. I think a 12 litre size would have been brilliant

[This review was collected as part of a promotion.] I purchased this along with the Duro Pro 7l a few weeks ago. I've used Osprey packs for trail running (local runs up to Ultras) for ever, as I really like the design USPs of the earlier black & white packs (e. g. magnetic clip, quick-release chest straps). Sadly these are gone now, and on the standard Duro packs. First good points: it really is no-bounce. I've done a 12. 5 and 10 mile runs and barely noticed it. They are both very light bags. I also love the WingStay removeable stabilizers; I've always preferred a reservoir for carry water, but these may sway me to using flasks, or at last offer alternative carrying options. Fabric used is nice and soft. Bad points: no key clip (weight saving?); emergency whistle is awkward to extract and use, chest straps are tied on to the pack, so far less quickly changeable than fixing mechanism on older packs; I'm not sure/convinced the zip pockets are waterproof. If not, this is a massive shortcoming if you are putting expensive phone in it. If you use a reservoir you have to retain the hose bite valve in one of the stash pockets or keep it restrained under a chest strap (another weight saving gimmick?). I would also hate to think what the white 10l bag will look like after a muddy run. Perhaps not the best colour to use. I also haven't really tried to quiver. I never use poles, but maybe in time this may help sway my running habits. I would also like to see a small external strap/loop to attach a rear LED light for running in the dark. Again, the older B&W packs had this (i have thought found I can attach my LED lights to the stretchy fabric sections round the back). I'll probably use the 10l bag for an attempt on 100-miler SDW I have planned soon. That will be probably be a truer test of the bag.

*Note: Going to be comparing this to the 2025 Osprey Duro 6 Model a lot since I brought the Duro Pro 10 as a replacement for it* I'm an avid trail runner/hiker and I was looking for something to replace my Duro 6 (2025 version) for a tat more room to bring carry some first aid gear (but don't want something like a Duro 15 with that ugly waist belt). I saw that the new Duro Pro 10 had dual front zip pockets and a 10 liter capacity so I opted to buy one. Unfortunately, it doesn't feel like it can carry anything more than my old Duro 6. There's 3 main compartments, two of them are open compartments that are not secure. One is for a reservoir, so if you're planning to carry one, that pocket is out of use. There's only one zip compartment in the back and it's small one. I don't think it can even fit a bigger smartphone. You can probably fit some keys and a wallet. The old Duro 6 has a better designed storage structure in my opinion. They also changed the fabric from past Duro. It is basically the same very soft type as a Salomon vest (Osprey also changed their strap system to copy Salomon's). Great for people that are casually jogging or doing urban races but I don't think it will last if you get snagged by a branch or tripped and fell on a trail with stones/sand. Not to mention, feeling the logo and decals on the fabric, I don't have much confidence on them to last. However, I can say that the fit of the Duro Pro 10 feels a little bit better than the past Duro 6. I think it because the fabric material is softer and less stiff. Also the dual front pocket is great for quick access to a wallet and your phone (if I was doing hiking, I would use one for gloves), I thought that idea was pretty good.
