Although one of the most highly regarded pack manufacturers on the market, Osprey is likely not the first brand that springs to mind if you’re on the lookout for a running pack. Their range of trail running vests, however, have proven to be a huge hit in the running world. Available in 4 volume variations, Duro/Dyna is a range of feature-heavy trail running vests that pack a punch for a relatively low price tag. Naturally, we wanted to see what all the fuss was about, so we decided to put them to the test. Our staff runners Tim, Jess, and Darcy have spent the past few months putting these packs through their paces across various environments and distances. Read more about it below.

 

Features of the Osprey Duro/Dyna Range

First, let’s run through the features that set the Osprey trail running range apart from other vests on the market.

 

It wouldn’t be an Osprey without durable design and materials. These running vests are made with an incredibly hard wearing and slightly padded nylon stretch mesh that is likely a lot thicker than vests most runners are used to – but we’ll wager that this vest will last the test of time in terms of durability. The zippers and hardware elements are (as expected) expertly crafted with quality in mind. As an added bonus, what this pack boasts in durability it does not compromise on in terms of environmental impact – the materials are 100% recycled, bluesign® approved and PFC-free.

 

Available in 4 different volume options and 2-3 different sizes in each volume, you’re guaranteed to find a vest in this range that suits your needs. Two snap-in, easily adjustable chest straps make it simple to achieve the desired fit depending on your load and layering system. Although it is comparatively heavier than other running vests on the market, the Duro and Dyna certainly make up for this in feature-density.

 

Staying true to the Osprey brand, their running vests don’t skimp on feature-set – the pocket set-up alone makes it stand out against the competiton. The LT version boasts 2 extra-large pockets to store soft flasks, 2 lower stretch mesh food pockets, a vertical zippered harness slash pocket for your phone, and a large dual-entry stretch mesh rear pocket. The 1.5L replaces this rear pocket with a hydration sleeve, front panel bungee storage, a stretch mesh front pocket, and 2 open stretch mesh side panel pockets. The 6L takes this a step further with an extra 2 lower stretch mesh food pockets, and a front panel zippered compartment. What else can they add, you may ask? In the 15L version you’ll find an even larger zippered compartment and two extra-large zippered lower hip pockets.

 

But it’s not just pockets. The Duro/Dyna range also includes a tuckaway safety whistle for emergencies and a plastic carabiner in the back pocket – a thoughtful touch for securing your keys. The 1.5, 6, and 15 versions come with trekking pole attachments for easy stowing on the move, as well as a handy clip in the back pocket to loop through the hydration bladder to keep it upright and reduce sloshing. Is there anything they haven’t considered?

 

In terms of hydration, each pack comes equipped with high quality Osprey Hydraulics hydration systems. The LT features two soft flasks that can stow easily in the large front pockets. The 1.5 & 6 come with 1.5L LT reservoirs, and the 15 includes a 2.5L LT reservoir that fits seamlessly  into the hydration sleeve with direct-zip access and a hose path for easy loading. Reservoirs feature an insulated hose to keep water cool as your body and/or outside temperature heats up.

Osprey Duro/Dyna Paddy Staff Reviews

 

Darcy – Osprey Dyna 6 Review

Use case: Long road runs and a few entry-level trail runs, ranging from 14-21K.

Darcy says: I am currently building up my running distance, and the Osprey Dyna 6 has everything that I need to push through my long run days. When I first put this pack on I was impressed by two things: first, the quality and robustness of material, and second, the immediate comfort. The pack conveniently slips on like a mini backpack and adjusts easily to allow the perfect fit, sitting securely on my frame so that there’s no unwanted movement. The range of pockets conveniently hold and organise all of my running essentials, with a dedicated space for everything including my phone, snacks, earphones, sunscreen and rain jacket. I particularly appreciated the included Osprey Hydraulics reservoir that makes it really easy to hydrate on the move, and secures seamlessly into the hydration sleeve on the back of the pack using a handy clip. 

In true Osprey style, it seems they’ve considered everything when it comes to the design, but I suspect that it might be a little too feature-heavy for some runners. On reflection, I would probably opt for the 1.5L version if I could choose again, since my runs are never too far from home and I probably don’t need all of the space that this pack provides. The material is quite thick and padded, so combined with the excess volume, it means that the pack is a little too heavy for me personally and makes me build up more of a sweat than I usually would. However, this pack is a great hybrid option for day hikes where I want to get a bit of running in, or if I don’t see a need to carry a full day pack. It has pretty much everything I need for around 6 hours in the mountains/trail on a fair day.

Favourite feature: There are so many pockets (12 to be exact) to fit all of my running essentials. Phone, snacks, rain jacket – whatever I need to bring with me there is a dedicated space for it, which makes the struggle of preparing for a long run that little bit easier.

Anything you would change: Although I love the range of pockets, the larger pockets on the back are hard to reach without taking the vest off, which can be a little annoying if you need to grab something mid-run. This doesn’t matter too much for shorter runs, and I always store the grab-on-the-go essentials in the front pockets.

Jess – Osprey Dyna 1.5L Review

Use case: Spring trail runs less than 10km

Jess says: I had a wonderful experience with my first running vest, the Osprey Dyna 1.5L. I used this vest on fairly short runs, so it was important to me that it didn’t feel too bulky – and I was not disappointed. It felt so comfortable to wear, even on rough terrain, with its lightweight design and mesh padding ensuring I didn’t get too hot. I loved the accessibility of the hydration system, the thoughtful positioning of the zippered front pocket, and the insulated hose for keeping your water cool.

My favourite feature(s): The lightweight design; the accessibility of the hydration system (being able to choose between the insulated water bladder hose and a soft flask (both of which could be tucked away when not in use) was convenient, as well as the zippered pocket that runs parallel to the hose at the back to easily remove the bladder from the vest; and the large vertical pocket that is the perfect size and position for a smartphone. I also loved that the hose of the water bladder was insulated so that the environment/my body didn’t warm my water up.

Anything you would change about the product: Although it is fantastic overall, I wish it had a few more pockets to organise my snacks, keys, and phone. The vest could also benefit from more customisable sizing.

Tim – Osprey Duro LT Review

Use case:  Road runs of a marathon (42km) or less. Nothing too much off road as it doesn’t have the storage capacity for larger items such as a running jacket.

Tim says: The Osprey Duro LT running vest stands out as an excellent choice for athletes or beginners seeking both comfort and functionality. The fit is notably comfortable, hugging the body without causing discomfort or restricting movement. The vest’s ergonomic design ensures that it stays securely in place during runs, preventing annoying bouncing or chafing, especially through undulating terrains. The adjustable straps and multiple sizing options contribute to a personalised fit, catering to a range of body shapes and sizes. This attention to comfort is crucial for long-distance runners like myself or those planning extended trail adventures, where a well-fitted vest can make a significant difference in overall performance and enjoyment.

The practical design of the Osprey Duro LT adds to its appeal for both novice and experienced runners. The vest features multiple pockets strategically placed for easy access to essentials like water, nutrition, and other small items such as your keys, phone or running jacket. The hydration system is especially well-executed, with two extra-large stretch mesh soft flask compartments that allow for easy on-the-go access to hydration without breaking stride. This practical layout eliminates the need to fumble with hand held bottles for the entire run or disrupt the running rhythm, making it an attractive choice for those who value efficiency in their gear. Additionally, the durable construction ensures that the vest can withstand the rigours of regular use, making it a reliable companion for various running adventures.

For individuals on the hunt for their first running vest, the Osprey Duro LT proves to be an outstanding option. It strikes a balance between comfort and functionality without being overly complicated, addressing the needs of beginners who may be discovering the benefits of using a running vest for the first time. The user-friendly design, coupled with its adjustable features and price, allows newcomers to the sport to enjoy the advantages of carrying their gear essentials hands-free without a steep learning curve. With the Osprey Duro LT, aspiring runners can confidently embark on their journeys, knowing they have a reliable and comfortable companion to support them throughout their training or races.

Favourite feature: The simplicity of the chest clip system.

Anything you would change: I wouldn’t change anything. I think Osprey has really nailed a great lightweight, simplistic running vest for a very reasonable price.

How does it compare to other vests you have tried? For the price range (more budget range) and the category (lightweight + simple) that this vest fits into, personally nothing compares. Yes, you can certainly spend more money on other vests from other brands which will be made from a slightly higher quality material and have different use cases with more storage options. But from the standpoint of having a great running vest at a decent price, that will do you for 90% of the running you’d want it for, there is no competition.
