Osprey Sirrus 24 pack for women is a great tool for day hiking and mountaineering tours, for biking and climbing, and for travel as well. This women-specific design backpack is full of features so typical for Osprey.
Note, this great pack has been modified and improved. See below the summary of changes.
Description – a great small pack with so many features
The size of Osprey Sirrus 24 backpack is such that it allows a lot of versatility. Its 24 liters of volume and various attachment possibilities make it a great pack for long day hikes and also for an overnight stay in mountain huts.
So if you plan some tour in the Alps which includes an overnight stay in one of the hundreds of huts there, do not think twice, this is a pack for you.
Sirrus 24 is a panel-loading type pack, with a long U-shaped zippered entrance. Inside the main compartment, you have a hydration sleeve.
The pack comes with an integrated rain cover, with its pocket located close to the bottom, on the front of the pack.
You have one loop on the bottom for ice axe or trekking poles attachment. It is accompanied with a tuck-away cord higher up on the front of the pack.
The suspension is based on a lightweight peripheral alloy wire. This wire runs around the pack and it provides tension to the mesh which is the only part of its body in contact with your back.
This is a great system which I like more than any other because it provides maximum ventilation that you can possibly expect. Such a system is introduced by Deuter and used also in some of Gregory’s packs. The warm air flows in all directions because the pack is completely separated from your body.
The downside of this system is that it usually (but not always, see Deuter Futura Vario backpack) implies a fixed harness. So you do not have harness adjustability here.
But Osprey has a solution for this because many of their packs, including this Sirrus 24 backpack, are made in several sizes, so you can choose in the moment of purchase.
This is a women-specific design, so you have nicely padded shoulder straps, with cutouts and covered by a spacer mesh. The load lifter straps are available, which allows for some very limited torso adjustability. The sternum strap is fully adjustable vertically and horizontally, and equipped with an emergency whistle.
As typical for Osprey’s packs, you have stow-on-the-go attachment loop on the shoulder strap, and the other part of this system is a loop on the side of the pack.
The hip belt is of the same material as the shoulder straps.
You have them 6 in total. Two nice zippered pockets are on the hip belt wings. Two stretchy mesh pockets are on the sides of the pack.
One small zippered pocket is on the top, and yet another zippered pocket with a key clip is also on the top but close to the back panel.
You have 2 straps on each side of the pack. The lower strap on each side is with Osprey’s InsideOut feature. This means that you can run it through the side pocket or over the pocket. The former option you will use when you do not have much stuff in the pack, and you want to cinch it down and to reduce the size of the pack in order to fix things which you have in the pack.
Additional 2 removable straps are on the bottom, good enough to attach a sleeping bag or a sleeping pad.
