Built for an amazing weekend.

Built with simplicity and comfort in mind, the Stratos 50 Backpack from Osprey Packs delivers exactly what you need for a quick overnighter or weekend backpacking trip. The nylon dobby outer fabric is durable, abrasion-, and water-resistant, though an integrated rain cover can easily be used when you run into a torrential downpour hiking through the rainforest. The Stratos is easy to pack with a separate sleeping bag compartment, as well as a removable, floating top pocket. Removable sleeping pad straps add to the bevy of configuration options. Mesh side pockets feature inside-out compression straps to ensure a smooth carry. A tool attachment is perfect for attaching an ice axe for quick trips around a glacier, and Osprey's Stow-on-the-Go trekking pole attachment makes it easy when you need to temporarily free up your hands to do a little scrambling.

Best of best gifts

  • Familiarity: I gave it as a gift but have feedback to share

Gave this as a wedding gift to a big traveling buddy, I was really impressed with the quality and setup. This will be the perfect travel pack for him, its not huge but it expands a ton. You can compress it enough to get it on as a carry on, but fully packed you could pack enough clothing for at least a week.

Osprey Stratos 50 Packs a Punch

  • Familiarity: I've used it several times

I first rented this locally for a weekend backpacking trip and was so impressed that I bought it for my next backpacking campout. It is light and durable - The configuration is well-thought-out and easy to pack. I really like the air-conditioned back panel that helps you to stay dry and comfortable even in warmer weather. The rain cover is a nice plus though I haven't tried it out yet. Overall, a great value.

According to the sizing chart the M/L size only fits up to 21" torsos. I have a 22" torso, would it be a better bet to find another pack that fits taller people?

prepping for PCT hike and looking for good backpacks for comfort and long extensive hikes. would you recommend this pack for such hiking, and if not which packs would you recommend? thanks!

Hey Brandon - this would be a great choice. This pack has good features, and some folks who do the PCT and other awesome thru hikes like less weight. So if you are weight conscious, please also consider the Exos 48. Stripped down and LIGHT!

Hope that helped!
