Hit the trail with everything you need.

Get out for a weekend or a week with the Women's Sirrus 50 Backpack from Osprey Packs. This lightweight hauler features Osprey's AirSpeed ventilated suspension system that not only carries your load smoothly, it also helps to keep your back cool, letting you hike for longer under the hot summer sun. Top-load access makes it easy to stuff everything inside that you need, and a separate sleeping bag compartment allows for some on-trail organization. A removable floating top lid and removable sleeping bag straps allow for easy customization of your load. To keep you hydrated, Osprey included an internal reservoir sleeve, and, speaking of water, an integrated rain cover ensures that you don't end up at camp with a backpack full of soggy clothing. A variety of pockets and tool attachment systems, including the Stow-on-the-Go trekking pole attachments, lets you bring along exactly what you need for your journey. Compression straps help secure the load if you're not heading out for as long.

Sirrus 50 Review

    My overall experience with the Osprey Sirrus 50 pack was a pretty good one. These backpacks are meant for longer day hikes and overnight hikes. I purchased this particular backpack for my first hiking trip with the intent of using it for many more trips to come. The Sirrus 50 has many good features with only a few minor setbacks.

    One great feature about this pack was light in weight making it easy to hike around in all day. The pads on the shoulders make it comfortable to travel with. The mesh back is very nice if you plan on any summer hikes. It keeps you cool and lessens the heat build-up between your body and the backpack. Another positive feature are the hip belt straps. These straps buckle together right above your hips and balance the weight of the pack from your shoulders to your hips. These features make this pack a great choice for any types of hikers.

    Since there are many great features with the Sirrus 50 that makes the back pack a little pricier. That being said, you will get your money’s worth if you plan on using it for multiple hikes. One minor setback with this product is there are limited colors for you to choose from. It is only available in blue or purple. Also, there are many small to medium sized storage components, but there is only one large storage component for the pack. If you are traveling alone, I would suggest this pack allows you to hike no longer than 2 nights (2-3 days) based on the amount of storage space there is.

    If you are willing to spend a little more for a comfortable hiking backpack, and don’t mind the bright colors then the Sirrus 50 is a great option. I hope you found all of this information helpful as you decide which hiking backpack to buy.

    Hey Taylor - it sounds like there are way more positives than negatives (colors and size of pockets)! Thank you for the review. I agree that 2-3 nights is perfect for this pack for most people. and its what this pack was intended to do.

    Osprey really nailed it on what they are trying to deliver: a multiday pack with awesome features (ventilated backpanel, lots of pocket options and a built in raincover, all for $180! Go Osprey!
