The Sirrus is designed specifically for women and has a clean and uncluttered design, superb ventilation and carrying comfort. This 24 litre size pack is perfect for days out in the hills and carry-on luggage for travel duties.

The key to the load carrying comfort and stability is the Airspeed trampoline 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 and breathability when in use. Building on the success of their previous back system, Osprey's AirSpeed has taken what they feature in their higher end, heavier weight and larger capacity packs and slimmed it down into a lighter weight and more flexible alternative, better suited towards smaller 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. The ergonomically shaped shoulder straps and the hip belt are made with Spacermesh foam, a stable and comfortable EVA with cut-outs to allow air flow.

Access to the main compartment is through a zipped front panel allowing easy access to the bags contents. 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. You can safely stash your trekking poles away when they are no longer required without having to remove the pack or pestering a mate to do it for you.

The women's Sirrus sets the benchmark for ventilated and comfortable 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.

Sizing Information

WS/WM torso length = 43 - 51cm

These measurements relate to your torso length and not your height. To estimate your torso length measure from the C7 vertebra (The C7 vertebra can be located by tilting the head down and finding the bone that protrudes at the base of the neck) to a line from the top of the hip bone (Iliac crest).

    I love everything about this bag as a summer/good weather rucksack. The length of the back of the bag can be extended and I found it is very comfortable to wear.

    The really useful feature of this backpacks is the adjustable back length. I have a long torso and womens backpacks often do not fit me but this one did as I could simply adjust (shorten/lengthen) the back of the rucksack. It has a wide hip belt which is handy when carrying fully loaded bag. There are a number of useful outside pockets and wet clothes compartment plus a rain cover and, importantly, the main compartment is not divided so you have plenty of volume for a daypack.

    The womens rucksack is lightweight, well constructed and very adjustable making it possible to achieve a much better fit than many on the market. After 77 miles it was still comfortable.

    Very well made. Keep sweat off your back effectively. Very adjustable so I imagine would fit a lot of people. Im a size 12 and it fits my hips very well and I can reach the hip belt pockets from the front. I can also get a water bottle from the side pockets and put it back without taking the pack off which is really handy. I stuffed my pack full of heavy books and put it on - as soon as I did up the hip belt the weight almost totally vanished from my shoulders. I get upper back pain but not with this pack :) Dont even notice I have it on.

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.
