Osprey Duro 15 Review

The Duro 15 is the largest of Osprey’s three backpacks designed for trail running.

Having already tested and used the smallest pack, the Duro 1.5, I was keen to look to the other end of the size scale to see what the 15 litre version had to offer.

Features:
The first thing I noticed about the Duro 15 was the number of storage options; the pack has no less than 8 zipped pockets and 5 mesh pockets, all of various sizes! The main zipped compartment on the back can easily hold items such as spare clothes, emergency shelter, waterproofs etc. whilst a rear stretch mesh pocket with clips gives faster access to items; useful when it’s an on – off waterproof day. A smaller rear, zipped pocket has a retaining clip for keys and can fit a wallet or phone. Two decent sized side zip pockets are big enough for hat, gloves and food and are just about accessible without having to be double jointed!

The zipped pockets on each hip are easily accessed on the run and provide another option for smaller items such as snacks, gels, compass, car keys etc. Finally a zipped pocket on one side of the chest is just large enough to fit a phone although it’s a tight fit if you have a full soft-flask on the same side.

On the front straps there are two deep, mesh pockets that house the soft-flasks or can be used as storage (another option for accessible phone storage). They also have elastic retainers for the soft flasks and an emergency whistle. Two smaller mesh pockets below these would hold a compass, gels, electrolyte or salt tablets etc. There are also two elasticated pole loops on the top shoulders for carrying lightweight hiking poles when not in use. To be honest I didn’t try to use these as I don’t have any poles, but I can’t see that they would be particularly easy to access whilst wearing the pack.

The Duro 15 offers versatile hydration options coming supplied with two 500ml soft-flasks with straws and a 2.5 litre bladder that fits into a dedicated zipped pocket with clip to keep the bladder in position. The bladder has a wide mouth which makes refilling and adding energy or electrolyte powder easy and the hose has a clever disconnector which allows the bladder to be removed whilst keeping the hose in place. This is really useful for mid run refills and stops you having to unthread and re-thread the hose and also makes for easier cleaning. The hose has a bite valve with a twist closure to prevent accidental leakage. Whilst running the hose can be kept in place by a magnet that attaches to the sternum strap. This does a surprisingly good job at keeping things in place but has the downside that you need to keep your compass well away from it! The magnets are easily removable if this is an issue.

If you don’t want to use the bladder, then two 500ml soft-flasks (supplied) can be stored in mesh pockets on the front of the pack on the lower chest. The long straws make drinking on the go fairly easy, however I found it quite difficult to get the full bottles into their pockets as the fit was too tight. Also it wasn’t possible to put the straws behind the straps designed to keep them in place without bending them in half (something I’m not sure is good for the straws). Osprey do make smaller 250ml flasks which are a better fit.

The Duro 15 is a unisex pack that comes in two sizes, Small / Medium or Medium / Large, mine being the smaller version. There is lots of scope for adjusting the pack with tensioning straps on the front, hips and waist plus elasticated straps across the chest that can be unclipped and attached in a number of positions.

The elasticated straps allow your ribcage to expand and so don’t restrict your breathing. The chest straps can be unclipped single handedly although I found them a little tricky to fasten at first. The back is slightly padded with a mesh design to help breathability and I found the pack comfortable, although as with any pack without a “back plate” you need to pack carefully to ensure that nothing hard digs in and causes discomfort.

At a touch over 500 grams the Duro 15 isn’t a super-light pack, but this means it is more comfortable and has more features than a lighter pack. With an RRP of £140 it isn’t cheap, but it feels like it is built to last.

What would I use it for?

The Duro 15 isn’t designed as a lightweight race vest, it is more suited to longer days on the hill where you need to carry more equipment, for example mountain running in winter or in bad conditions. It would also be a good choice for multi day races or for supporting long distance challenges such as the Bob Graham Round where you need to carry equipment for someone else as well as your own. I would also use it as a summer walking pack.

Pros:

Loads of storage, good hydration options, comfortable.

Cons:

Difficult to get the 500ml bottles into their pockets!

Verdict:

A comfortable pack with lots of storage and hydration options. Ideal for long, remote runs, multi day events or runs where slightly more carrying capacity is needed.

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.

2 rear pockets for kit & optional bladder

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.

2 decent sized stretch rear side pockets

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!

reaching the rear side pockets was tricky!

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.
