What is the Tempest 33 Extended Fit?
The Tempest 33 EF is the updated version of an Osprey classic, which comes with an extended fit to fit larger frames, fitting up to 70-inch hips, plus extended shoulder straps, easy-reach repositioned pockets and a longer sternum strap. It's a 33-litre backpack made with durable, recycled materials that provides optimum functionality and performance for hiking, hill walking, and short multi-day trips.
What is it made of?
The main body is made using high-tenacity nylon with a triple ripstop. This fabric is incredibly durable and abrasion-resistant, allowing it to survive regular use in rugged terrain.
The Tempest's base and liner are made with 420HD nylon packcloth, which is incredibly durable. Thus, this backpack will likely last a lifetime.
All of these materials are 100% recycled, and bluesign® approved. bluesign® certifications ensure that the materials used avoid harmful substances, use reduced air and water emissions, increase resource productivity, and that the production line is more transparent and trustworthy.
All materials are also treated with PFAS-free DWR (durable water repellent), encouraging light rain and snow to bead off the material instead of soaking in. PFAS-free treatments avoid the use of harmful 'forever' chemicals. PFAS is a toxic chemical known to harm humans and the environment. It was previously commonly used in DWR treatments; however, many outdoor companies are now working to eliminate these chemicals from their production lines to contribute to a more responsible manufacturing process.
What backsystem does it use?
The Tempest backpack has an Airscape backpanel, which uses an injection-moulded AirScape framesheet with die-cut foam. This backpanel provides a close-to-the-body, stable fit and is incredibly flexible to amplify comfort and freedom of movement. It uses ventilated airflow channels for active users, helping to prevent sweat build-up, and a mesh-covered foam lumbar for lightweight comfort.
It also uses a BioStretch harness, which features integrated BioStretch seams (stretchy seams) that maximise flexibility without sacrificing stability for dynamic movement in technical terrain.
Spacermesh over die-cut foam on the harness and hipbelt provide a breathable, comfortable contact surface that manages temperature regulation efficiently.
The hipbelt also features the Crossbody ErgoPull system that helps to pull the lumbar into the body for improved weight distribution and to help prevent lower back pains or injury.
You can easily adjust the harness to fit your torso length, plus the sternum strap to help keep the pack stable.
A seamless lumbar-to-hip-belt body wrap and additional BioStretch seams provide further flexibility.
What features does it have?
To optimise performance for larger bodies, this refined design features an extended hipbelt that fits up to 70-inch hips, extended shoulder straps, easy-to-reach repositioned pockets and a longer sternum strap.
At the top of the backpack, you get a fixed top lid featuring an external zipped pocket, and an under-lid zipped mesh pocket with a key clip that works perfectly for small valuables like car and house keys or a wallet.
You can access the main compartment via the top-loading opening, which provides ample weather protection and extra organisation options. You also get a large, stretchy mesh pocket on the front, stretchy mesh side pockets, an expandable mesh harness pocket and dual hipbelt pockets, which are ideal for keeping snacks and energy gels handy.
This pack has a hydration sleeve for those who prefer using a hydration reservoir instead of chunky water bottles for hands-free sipping.
If you're adventuring during winter, you may be pleased to hear that there are tuck-away ice axe attachments with bungee tie-offs; these attachments safely store ice axes while helping prevent them from piercing your backpack on the move.
Stow-on-the-go trekking pole attachments provide storage for your walking poles when not being used.
Lastly, upper and lower-side compression straps will cinch in dead space when the bag isn't fully packed to help prevent your belongings from rattling around inside.
