Description

Built for long day hikes and lightweight overnights in the backcountry, the lidded Osprey Stratos 36 pack combines carrying comfort ventilation and organizational features to deliver lightweight technical performance.

Employing Osprey's Airspeed Suspension with a 3.5mm LightWire frame, the pack's tensioned mesh back panel provides flexible support and breathability to combat heat build-up between your back and the pack body. Both the hipbelt and harness straps are padded with die-cut foam and covered in mesh to enhance comfort and optimize fit. The hipbelt utilizes an ErgoPull closure that provides leverage when tightening so you get a snug fit and optimal load transfer. An adjustable sternum strap is equipped with a safety whistle for emergencies.

This pack has an internal volume of 2197 cubic inches, or 36 liters. The adaptable suspension system can adjust to fit torso lengths from 18" to 22", making this pack suitable for a wide range of users.

Under the fixed lid, a drawstring closure provides access to the main packbag. There's also a hidden vertical side zipper and a zippered lower compartment with a floating divider for additional access. A front zippered stash pocket, two side stretch pockets, and dual pockets on the pack's fixed lid offer additional organizational options. A fitted raincover is included for protection from the elements.

Other features include a Stow-on-the-Go trekking pole attachment, removable sleeping pad straps, side compression straps, an ice axe tool loop with a bungee tie-off, gear lash loops, and zippered hipbelt pockets. An internal sleeve and drinking tube pass-through make the pack hydration compatible (hydration system sold separately).

Constructed of bluesign approved recycled fabrics with a DWR finish, the Osprey Stratos 36 internal frame backpack is available in your choice of color options.

Capacity increase at the cost of some thoughfulness

Likes

As a long time user of the Stratos 24L for day hikes, I was looking for something with a little more capacity for when I'm doing long hikes solo. The Stratos 36L was appealing with it's enclosed main compartment that allows you pack things in without putting a strain on zippers. As a photographer, I also like that it has side access to the main compartment for the times I carry my camera with me and want quicker access without unloading the pack. The ladder system makes height adjustment a breeze and the design of the adjustment straps make loosening and tightening on the go incredibly simple. I was a little confused by the design of the drawstring on the main compartment at first as it wasn't initially intuitive like many of the push button ones I've dealt with in the past. Instead I've discovered that it's design allows it to be opened and closed one-handed, which is fantastic. I'm surprised this feature isn't talked about in video reviews for this pack. Finally, the bottom sleeping bag compartment is great for storing those "just in case" items that I take on every day hike, without them getting in the way of the rest of the pack.

Dislikes

While 90% of this pack was well thought out, there are a few design changes that they seemed to not have put much thought into that keep this from earning 5 stars. First, as many reviews have claimed, mesh pockets on the sides are TIGHT with a standard 1L Nalgene or 40oz single wall Kleen Kanteen. Even when the pack is empty. They also lack the secondary hole to pull bottles from the bottom that so many other Osprey packs have. As a result, it's pretty much impossible to get a water bottle out without taking the pack off. There was also not much thought put into the zippers on the hip belt pockets. With my old Stratos 24L, I could zip and unzip one handed with ease. On the new Stratos 36L, while you can unzip one handed, you can only get the zipper about half way closed without reaching around with your other hand to assist with closing. It appears no thought was put in to stitching it in a way that anchors the pouch flap and provide something to pull against. Finally, the rain cover, while removeable, seems to not be wide enough when deployed to fully cover the sides of the pack when you have 1L water bottles in the mesh pockets. It leaves a 1-2 inch gap on both sides that could potentially let rain into the lower portions of your pack. I don't know how much effect this will have on water getting into the pack yet, but is yet one more design flaw that does not exist on the older Stratos 24L.
