Why We Like The Sirrus 24L Backpack

The second you put on the Osprey Women's Sirrus 24 Backpack and feel its mesh AirSpeed back panel successfully transfer the load to your legs, you get overwhelmingly excited, at least we do. The AirSpeed suspension system combines the rigidity of aluminum stays with a tensioned mesh back panel for effective load transfer and cross ventilation, while the Women-specific Spacer Mesh hip-belt and shoulder straps ensure our load rests where it should for max efficiency and pain-free hiking.

Great pack but not for petite body.

The Sirius 24. Is durable and well-constructed. However, on the trail I discovered the waist belt cannot be adjusted to fit a small frame. The shoulder straps were adjustable but also could not be adjusted sufficiently for my small frame. I recommend the pack based on its utility and construction however one should carefully consider the adjustments if you have a small frame.

I am an Osprey girl

[This review was collected as part of a promotion.] I am an Osprey girl for life! The airspeed mesh back is a must! I hiked with a standard Stratos24 for 10 years. I went to a shop to try on new packs and the Sirrus fits like a dream! The extra pockets are in the right places!

Over engineered

First let me say, I'm a fan of osprey packs however this daypack doesn't seem to pack well imo. If you put a full bladder in the pack, it doesn't leave a lot of space for anything else. I felt it had too many pockets and zippers which just added to the weight. The hipbelt pockets were too small to hold a regular iphone. I had to return it, hopefully it will be updated.

Great fit; nice daypack

I have two other Osprey packs and love the women-specific features. I bought this Sirrus for casual hiking and walking to town for groceries and other supplies. I got the right fit after watching a Youtube that showed that the hipbelt pad in front should be centered over the pelvic bone - not above it as I had incorrectly done. The torso adjustment "ladder" is a nice feature. I am 5'7" and measured my torso at 15.6", and found the second shortest adjustment to work the best at keeping the shoulder straps from riding up. This is really a comfortable and well fitting pack for me.

Nowhere to carry phone for easy access

Regular iPhone doesn't fit in hip pockets and there's nowhere to carry your phone in the pack for easy access. This is a super annoying! Everyone needs easy phone access- whether it be to access downloaded trail map info or for taking photos. I didn't like the way that trekking poles are stowed either. They kept coming loose and swinging (It could've been due to the hiking terrain of climbing and bending?) Apart from that, the pack was very comfortable on a 12 mile hike with a lot of bouldering and climbing. I'm 5'9 and the fit was perfect. I wouldn't buy this pack again or recommend it- there are other packs out there that can accommodate a phone.

Beautiful pack with one problem

The pack is sturdy, has lots of pockets and has useful features like a whistle, attachable rain cover and breathable back. Unfortunately I can’t use it as the pockets on the hip straps are placed right where my forearms hit. They leave rub burns on my arms and there doesn’t seem to be a way to solve the problem. I’ve tried several times with the same issue to the point I’ve taken the pack off during a hike. I’m disappointed as I really wanted it to work but can’t get around the pockets brushing against my arms.
