Osprey Duro 1.5 Review

Osprey, the Californian company renowned for their packs and rucksacks have introduced a new range of trail running backpacks for Spring 2017 – the Duro. Available in three sizes; 15, 6 and 1.5 litres, here I review the smallest, the 1.5L version.

Features:

The Duro 1.5 is a unisex, minimalist vest type pack, available in two sizes; S/M or M/L. It comes supplied with two 250ml soft-flasks with straws. The pack I tested was the S/M version which weighed 283g on my scales (without flasks)

The back of the pack has two zipped pockets with large zip pulls making them easy to open. The smaller pocket has a handy key clip and will just about fit a windproof or minimalist waterproof top whilst the slightly larger, deeper pocket is designed to carry a bladder (not supplied). I found that I could easily fit a set of lightweight waterproofs into the larger pocket.

On the top of each shoulder there is a small elasticated bungee that is designed to hold a pair of folded walking poles.

There are also two stretch mesh pockets at either side / back of the pack. These can easily take hat, gloves, food etc and I even managed to stuff a small windproof into one.

On the front there are four stretch pockets, two on each side. The larger, top pockets house the 250ml soft-flasks that come supplied with the pack and have small elasticated retainers to keep the flasks from moving around (these also make a handy attachment point for a compass). The two lower, smaller pockets are again handy for hat, gloves, food and compass. There is also a whistle attached to the inside of one of the upper pockets.

There is also a vertical zip pocket on the front left which is big enough to take a phone or sections of map.

The pack is fastened by two elasticated sternum straps that clip across the chest and can be removed and re-positioned in 6 positions. One of the straps has a magnetic clip designed to hold the drinking tube on the optional bladder. This can be easily removed if you don’t intend to use it. I would take it off so that it doesn’t interfere with your compass. The straps can be easily adjusted to fit your chest size.

There are two more adjustment straps on the side allowing the pack to be tensioned according to size of the wearer and how much kit is being carried.

The whole frame of the pack is slightly elasticated with a ventilated mesh fabric on the inside where the pack is in contact with your body. The graphics on the pack are reflective which is a useful feature if you find yourself running on unlit roads in the dark.

How it performed:

I wore the Duro 1.5 over a couple of weeks, with and without the soft-flasks on runs of up to 10 miles at different paces and also lent it to clients on group runs to get their feedback. My first impression was that it was very comfortable to wear, fitting snugly without being too restrictive as the material stretches slightly as you move and breathe. The bottles didn’t bounce excessively even when running at a fast pace. I was impressed by the amount of storage there is despite the pack’s small size; hat, gloves, map, compass, whistle, food, drink and phone are all accessible without having to take the pack off.

If you intend to use the large rear pocket to carry items you need to pack it so that nothing digs into your back (just as you would with other lightweight packs) and the rear / side pockets are difficult to reach whilst wearing the pack. I found a way of reaching round the back with both hands that helped me remove and replace things from these pockets – ok at easy jog pace but difficult to do whilst running quickly!

The supplied soft-flasks are only 250 ml each. This has pros and cons – the weight is more evenly distributed, particularly if you only take one flask but at the price of not being able to carry much drink. I would prefer larger flasks (I tend to only take one flask as it’s less hassle – only 1 to fill and clean etc – plus extra storage space in the spare pocket) I found that it is possible to swap in a long, thin 500 ml flask although the elasticated retainer doesn’t fit (this wasn’t a problem).

I found that fastening the chest straps could be a bit fiddly, especially when wearing gloves. The plastic clips need to line up to locating points on a plastic rail and if you don’t line them up exactly they don’t clip on. A simple buckle would have been easier to fasten.

I don’t use poles whilst running so I didn’t test the pole holders. I certainly think you’d have to be either very well practised or a contortionist to stow and remove them without taking the pack off!

The pack looks really neat, the bright yellow and black is a nice colour combination but mine came with grey chest straps that look a bit out of place (am I being too fussy?)!

What would I use it for?

The Duro 1.5 is just the right size for when you can fit all your kit in your bum bag but doing so makes it really big and bulky. So for example on runs when I want to carry waterproofs and a drink, yes I can fit it all into a bumbag but the bumbag then bounces around whilst I’m running. I would use the Duro 1.5 on long summer runs when I need to carry water but little in the way of clothing or on races where full kit is needed which makes my bumbag too bulky.

Recommended Retail Price is £60

Verdict:

A comfortable, well designed running pack with plenty of storage options despite its small size. Ideal for runs or races where you need to carry just that bit more than comfortably fits into a bumbag.
