For a long time, I have been a fan of Osprey rucksacks for running and other outdoor pursuits. As a brand, they offer a female version of some bags, which can be really important when ensuring the correct fit. Recently, I had the opportunity to test out the Duro 15, a unisex hydration pack. My usual go to bag for run commuting is their Tempest 20 which has room for snacks, a change of clothes, my lunch, sunglass case, and a large wallet plus water pouches on the shoulder straps. I was curious to see if removing five liters and having a unisex design would be noticeable.

The bag was extremely comfortable as soon as I put it on. The mesh fabric used to line the area that will be against your skin never chafed or scratched. It is very soft and helps with breathability. The front chest strap is adjustable so you have find a level that fit your body shape. There is also a hip belt which helps support the bag if it is full, especially if you are running. Keeping the bag close to your body assists with balance and center of gravity. The hip straps also have zippered pockets which are super handy for snacks, your phone or a debit card- things you may need quick access to while you are out and about. There are also small zippered pockets that you can use to keep organized, which is very appealing to me.

As a hydration pack, this bag offers both a 2.5L bladder and two 500ml pouches.  I think this gives it versatility and the options to take as much (or little water) as you need.  Of course, the bladder will take up extra space leaving you less room to carry things like extra layers.  For me, the missing 5L made the bag a little shorter than my Tempest 20 and therefore slightly more comfortable.  The Tempest 20 does have an adjustable torso length to help with the fit but the though that the Duro 15 was too big for me never crossed my mind.  I couldn’t fit both my changes of clothes and lunch in the Duro 15 but if I planned ahead for run commuting, it didn’t impact me.  I would either leave a change of clothes at work or buy lunch in the canteen.  Or if I was going on a long run and just needed to carry an extra layer and water, this bag is perfect.

Overall, I really enjoyed running in this bag. Even though I couldn’t cram all of my stuff in there, it was probably better for my body not to carry that much weight. Running with a rucksack (no matter what size aside from my 1.5L) always influences my posture and therefore running form. I like being prepared though, so tend to carry more than I need just in case it rains, I can’t find a shop, or I get injured. Of course, being restricted from carrying so much has benefits on my running performance. Looks like I should switch to the smaller pack to ensure my commute doesn’t turn into junk miles.

Thanks to Osprey for the complimentary bag. All opinions are honest and my own.
