Osprey Sirrus 24L Pack Review
I just want to start out by saying that I’m a HUGE fan of the Osprey Sirrus 24L pack. In my opinion, it’s the perfect day hiking pack for women. I’ve easily worn it on more than a hundred hikes and it’s still in fantastic shape and condition (and truthfully, I don’t clean it as often as I should).

To rewind, I bought the Osprey Sirrus 24L pack in early October 2021, shortly before hiking Rim-to-Rim across the Grand Canyon. I needed a pack that was durable, but also comfortable for an extra long day on the trail. Not only was the Osprey Sirrus 24L pack the perfect size to hold all of my gear (including an extra pair of Altra Lone Peaks to give my feet some relief in the middle of the hike), but it fit perfectly and didn’t weigh me down during my hike.
Depending on the type of hiking you do, a 24L daypack may or may not be the right size for your needs. If you tend to go on shorter hikes during nice weather and aren’t carrying a ton of extra layers, then a 24L pack is probably more than you need. But, if you’re like me and do longer hikes year-round in a variety of conditions, then the Osprey Sirrus 24L pack is the perfect day pack for all of your gear.
This pack has stood up to the test over the past 3 ½ years and still has so much life left in it. From the fit, to the color, to the quality, I think there’s a lot to love about the Osprey Sirrus 24L pack. Keep reading to learn more about the top features, and the pros and cons of the pack.

Top Features of the Osprey Sirrus 24L Pack
AirSpeed Suspension System
One of my favorite features of the Osprey Sirrus 24L pack is the AirSpeed suspension system. This ventilation system is a feature of many Osprey packs and allows your pack to sit away from your back. Not only does this help the pack fit comfortably, but it also allows air to flow through so you don’t get super sweaty.
Hip & Chest Straps
One of the features that sets the Osprey Sirrus 24L pack apart from other women’s hiking packs is the hip strap and chest strap, which comes with an emergency whistle. I’ve noticed that a lot of smaller day packs either don’t have a hip strap, or if they do, it’s flimsy and similar to the chest strap. The hip strap on the Osprey Sirrus 24L pack is thick and padded like a backpacking pack, so it actually provides support. There are also pockets to store snacks or gear that you need easily accessible.
The hip and chest straps are just 2 of many adjustable straps on the Osprey Sirrus 24L pack. While the backpack only comes in one-size, you can easily adjust it for the perfect fit!

Endless Pockets
One of the benefits of a 24L pack is that there is a lot of room for pack designers to work with. The Osprey Sirrus 24L pack comes with a variety of pockets and pouches to keep your hiking gear organized and secure.
There’s one large, main pocket that has space for a water bladder (I regularly use a 3L water bladder), and a mesh pouch with a separate opening on top. The back of the pack has a small opening for your water bladder hose to pop out. On the front of the pack is a small pocket with a horizontal zipper, and a separate, larger pocket beneath it with a vertical zipper.
The hip straps also have small pockets, as previously mentioned. Additionally, there’s a loop for an ice axe, as well as mesh pockets for water bottles on both sides of the pack (this is typically where I keep my phone).

Pros & Cons of Osprey Sirrus 24L Women’s Day Pack
Pros
Durability. The Osprey Sirrus 24L pack is made primarily from recycled nylon, which makes it an extremely durable hiking backpack. I’ve put mine through the wringer squeezing through slot canyons and bushwacking, and my pack is still in excellent condition after 3 ½ years.
Ideal For Every Season. I’ve used the Osprey Sirrus 24L pack in every season. During the winter it’s helpful to be able to carry extra layers, while during the summer there’s plenty of room to carry a camp stove for some mid-hike coffee.

Fun Colors. The current version of the Osprey Sirrus 24L pack comes in 4 colors – elderberry purple, tunnel vision grey, succulent green, and muted space blue. My pack is a deep purple-magenta color. It’s from 2021, so it’s unfortunately no longer available, but the current elderberry option is fairly comparable.
Raincover Included. The Osprey Sirrus 24L pack comes with a raincover, which not only helps protect your pack during inclement weather, but also saves you from incurring an extra expense.
Cons
Cost. I would say the only real drawback to the Osprey Sirrus pack is the price. At $180, it’s definitely a pricey day pack. I think this pack is best suited for someone who hikes fairly regularly, and enjoys long, challenging hikes, and/or winter hikes. While I’m not a mom yet, I imagine it’s going to be a great pack for carrying extra snacks and gear for kiddos. With that said, if you’re an occasional or casual hiker, I think there are more affordable options out there.
