The Stratos is a great looking trekking day pack with impeccable ventilation thanks to the mesh back system. The key to the load carrying comfort and stability is the Airspeed mesh back panel; a lightwire frame effectively transfers weight to the hip belt whilst the sprung mesh panel keeps the pack away from your back allowing full ventilation when in use. Building on the success of their previous back system, Osprey's AirSpeed has taken what they featured in their Exos, Atmos, Aura and Ariel packs and slimmed it down into a lighter weight and more flexible alternative, better suited towards lighter packs such as this one. The foam now covers the entire back and hip belt and offers seamless comfort only previously used in their top end packs. Not only this, but the back system is fully adjustable to suit a wide range of back shapes and sizes. 

This extremely comfortable pack works effectively in all conditions and the roomy 50 litre capacity is suited to long days out, lightweight multi-day trips or weekend breaks away. Alternatively it makes an ideal travel bag due to the excellent venting and light weight. 

Both the shoulder straps and the hip belt are made with Spacermesh foam, a stable and comfortable EVA with cut-outs to allow air flow and allow a little stretch for ease of movement. Access to the main compartment is through a traditional top lid that offers security and additional compression if required. The main compartment is split into two by an internal zipped divider which helps to keep wet dirty kit separate or the base compartment can be used to store a sleeping bag on overnight trips. To avoid having to pull out all your kit just to get to something right at the bottom of the pack, the Stratos unzips vertically from the front, allowing access to the whole pack from the front and the top.

You get all the usual and useful Osprey features with this pack such as the internal hydration sleeve, zipped hip belt pockets, stretch side pockets, integrated and detachable raincover  and the brilliant Stow-on-the-go trekking pole attachment system. This brilliant system allows you to safely stash your trekking poles away when they are no longer required without having to remove the pack or pester a mate to do it for you.

The new Stratos sets the benchmark for ventilated hiking packs.

Care & Advice

Getting the correct fit for your rucksack is as important as getting the fit right for your boots. A badly fitting pack can inflict misery and discomfort and completely ruin your adventure. This guide is designed to help you get the best fit and comfort from your chosen pack so that carrying all your kit becomes a pleasure and not a chore.

ADJUSTING THE BACK LENGTH

If the pack has an adjustable back length, adjust this to your correct level. Your back length is not related to your height but your torso length. Many packs, and specifically the bigger and more technical packs are available in different back lengths or feature adjustable back systems. Contrary to popular belief, your torso length and not your overall height is the key to getting a well fitted pack. Tall people don’t necessarily have long torsos, just as shorter people don’t always have a short torso length.

Your torso length can be found by measuring from your C7 vertebra (the bony protrusion at the back of your neck when looking down) to the height of your iliac crest (top of your hip bones, where you put your hands on your hips). This measurement will give you an idea of which pack back length to choose.

Once you've got the back length sorted, either by selecting the correct size pack or adjusting the back system, you can begin to follow these simple steps to help achieve a comfortable carry.

LOOSEN OFF ALL STRAPS

Before you start fitting the pack, loosen off all the straps as this will make it easier to get the correct tension later.

TIGHTENING THE HIPBELT

Fasten the backpack hipbelt, the general position is the same as where you’d put your ‘hands on hips’ This area is called the pelvic girdle, and what you can feel when you rest your hand on the area is the bony protuberance, the iliac crest. The iliac crest can support the weight from a pack comfortably, and for sustained periods. The padded section of the hipbelt should encompass this and fit securely.

Tighten the straps so the hipbelt feels secure and held firmly around your body. Ensure that the lumbar pad is centered to your lower back to give you maximum support. Remember that your hips carry most of the weight of the pack, so this should be firm but comfortable.

ADJUSTING THE SHOULDER STRAPS

Next, adjust the shoulder straps, pull them until they start to become snug, but ensure that they are not too tight as to lift the pack off your hips. Remember tightening them will stabilise the pack but will increase pressure over the shoulders. If the back length of the pack is correct the shoulder straps will be flush to your shoulders whilst the hipbelt sits in place comfortably. The point where the shoulder straps attach to the main body of the pack should be roughly half way down your shoulder blades; this ensures  that the shoulder straps rolls evenly over the top of your shoulders to distribute the weight correctly.

FASTENING THE CHEST STRAP

Fasten the chest strap and pull until taut but not tight, the elastic section should not be extended. This helps keep the shoulder straps from catching in your shoulder joints and keeps the stability of the pack when moving over rough ground.

ADJUSTING THE TOP TENSIONERS

Top tensioner straps link the shoulder straps to the top of the pack. When tightened, their main function is to stabilise the top part of the pack. The optimum angle for these straps in 45º, but they will stabilise the load even when horizontal or at a more obtuse angle. Tighten them until you feel the top part of the pack rest against your pack, over tightening them will create excessive pressure on the front of your shoulders.

ADJUSTING THE SIDE TENSIONERS

Side tension straps are linked to the hipbelt. By tightening these straps you can stabilise the load but reduce the hipbelt flexibility. Where balance is critical tightening them can help you feel more secure. However, if you are striding out over easy terrain it’s better to loosen these straps to allow full hip flexibility.

ADJUSTING THE SIDE COMPRESSION STRAPS

Side compression straps come next, pulling these tight does two things: firstly, it stabilises the load, secondly it can lift the lower part of the pack, repositioning the load closer to your back.

ADJUSTMENTS ON THE GO

Following these steps should give you a comfortable but secure fit on your pack. Sometimes adjustments will need to be made on the go depending on the terrain or the load you are carrying. The perfect fit is very much a personal preference so experiment with different tensions on the pack to find what suits you best.

    Osprey Stratos 50 Black ,  On

    Only used it on a practice yomp but seem very comfortable with a 10kg load. Plenty of adjustment for a good fit - trampoline back reduces the sweaty back problem. I will be getting a webbing trouser belt as my leather belt is too thick and tended to interfere with the rucksack waist harness. Overall very pleased

    Osprey Stratos 50 Black ,  On

    I bought this to replace my old Lowe Alpine Airzone Pro 35:45. Gotta say, if the Osprey Atmos AG is the ultimate in comfort, then this Stratos 50 is only a fraction behind. Its very comfortable. The trampoline mesh back offers excellent ventilation with plenty of torso adjustment. Also, if you dont want your water bladder inside the pack, you could store it outside, behind the mesh panel. The Hip-Belt offers solid support & its pockets are a generous size. The Stratos 50 can be cinched down quite small and used as a less bulky day hiking pack but then has plenty of room for a weekend adventure. The lower sleeping bag compartment doesnt unzip to make one large space but the divider is like a large bellow, allowing you to fill from the top all the way to the bottom. Excellent! This pack does everything I need it to do. It weighs about 1.7 kg, so its roughly half a kilo heavier than the Exos and half a kilo lighter than the Atmos. My only concern is the side water bottle pockets are only mesh and may get ripped off Im not careful. Overall all, Osprey quality. Very happy.

    Osprey Stratos 50 Black ,  On

    Bought this as I was after something smaller and lighter than my current 65L rucksack. Only used once so far on a weekender so maybe a bit early for a review, but impressions so far. Pros: The suspension system/trampoline back - Osprey do this really well. Plenty of adjustment on torso length. Good cushioning on shoulder straps and hip belt. Weight - at 1.7 kg its much lighter than my previous packs. Full length side zip - probably more use to travellers than hikers. Cons: Front pocket not mesh or stretchy so not best suited for wet gear although there is a drain hole. No stretch to side pockets- seem a bit flimsy. Top lid attachment straps are fiddly and interfere with load lifter straps. Top lid is removable but no flap jacket as some of their other packs. Hip belt pockets very small and almost impossible to open or close one handed when hip belt is cinched. Overall impressions: None of the Cons are a deal breaker. A fairly decent pack that seems to be built down to a price.

Thanks for choosing this item ...

Osprey Stratos 50 Black

Would you like to see the special offer we have for you?

 

   

The whole ordering and delivery process went very smoothly but unfortunately the boots I had ordered were slightly too narrow and had to be returned, the no quibbles returns process was quick and easy, with Trekitt keeping me informed by email at every step of the way, including receipt of my parcel and when my refund had been processed. Service and communication with this company always excellent.
