The supremely ventilated, featured and durable Osprey Stratos Series receives a makeover that is more than skin deep. Now featuring adjustable torso lengths for improved fit and comfort with updated aesthetics, the Osprey Stratos 34 Litre Backpack is the go-to choice for those who prefer panel-loading organization on everything from short day hikes to lightweight overnights in the backcountry no matter how far, or near. When the weather turns, fear not - Stratos keeps your gear and pack protected with an integrated raincover. Smartly organized pocketing keeps all your equipment where you need it, when you need.

Sizing and Fitting of your Osprey Pack

Fit is the key to pack performance. Take the time to get it right. Most Osprey packs are available in multiple sizes to fit a range of torso lengths. To find your torso length, have a friend measure your back along the spine (as shown in the picture below) from the level of your iliac crest (the top of your hipbones) to your C7 (the knobby bone at the base of your neck). Use the table below to determine your pack size.

Outdoor Gear Lab Editor's Choice Award

"This is a great pack for dedicated day hikers. Avid day hikers are tackling peak lists, covering hundreds of miles a year, and own specific gear for these pursuits. This is a purpose-built day hiker's pack. The rigid suspension supports loads of all sizes and holds the pack away from your back for optimum ventilation. The set of pockets and straps is carefully designed to carry what you need for all season hiking. The result is a pack that is perfect for hiking but is a little too bulky for day-to-day or multi-sport use. We have granted two Editors Choice awards in this category, representing the two different types of users we encounter seeking a "day pack." The Osprey Stratos 34 is for the hikers. The Osprey Talon 22 has the same attention to detail and careful choice of features. But its less rigid back panel and less free-flowing ventilation system are better for those that want an all-around bag for hiking, commuting, rock climbing, cycling, and traveling."
