Osprey Airscape

Osprey Airscape
Osprey's AirScape™ mesh covered ridge foam backpanels set a new standard in the industry. With its ability to keep the weight close, provide cushion, allow ventilation and add load carry is quite a list of needs from this unassuming backpanel. It successfully accomplished all of that in a way that allows it to be used in the large gear hauling packs and lightweight day hiking packs.

Osprey Peripheral Frame

Osprey Peripheral Frame
Peripheral frame was a departure from the norm many years ago and it’s still the foundation of our gear hauling packs. A wire frame runs along the outside of the backpanel directly connecting the upper load lifters and the central core of the pack to the hipbelt to transition and spread the load. Allowing natural torsional movement, effective adjustable torsos, and different load range and backpanel builds makes this suspension design truly innovative.

Osprey Framesheet

Osprey Framesheet
Whether connected to a peripheral frame on a big load carrier or as a standalone suspension on a day pack, a well-designed framesheet effectively spreads and transitions the loads across the entire body to the harness and hipbelt. With different material and stay options Osprey can make sure each individual pack has the right load carry for its intended use.

OSPREY MEASUREMENT GUIDE

Please note that the info provided above refers to the torso size each pack will fit, and NOT any dimensions of the pack. Below are some steps for how to get your torso length. You should probably have someone help take this measurement for you so it is accurate. And they might accidentally touch your butt.

HOW TO MEASURE TORSO LENGTH:
• Start at the iliac crest, which is the top of the hipbones on the side of your body. These act like a shelf for supporting a pack hipbelt.
• From this level on your spine, measure to the C7 vertebrae, the knobby bone at the base of your neck when you put your head down.
• Make sure you keep your back as straight as possible while measuring.
• This torso measurement determines what size Osprey pack you should carry. Refer to the size charts above to find your ideal size.
• If you are in between sizes, it is ideal to try them both on before ordering.

HOW TO MEASURE HIPBELT SIZE:
• Measure around your hips at your iliac crest, NOT your waist.
• A properly fitted hipbelt rides centered over the hipbones and needs to be very snug.
• The padded portion should wrap well around your hips, leaving a gap of 3 to 6 inches between the tips of the both hip pads when securely tightened.
• Refer to the Hipbelts size chart above to help determine your ideal Osprey pack size, but again, your torso length is what should determine your pack size, NOT the hipbelt.

Rated 5 out of 5 by from Great ascension, touring, daily pack! I picked up this pack as a good middle between my Osprey Atmos 65L and my Osprey Raptor 10L. The Mutant is extremely lightweight an has some great features for winter ascents and lightweight backpacking. It is also a great option if you're trekking in with a lot of climbing gear (ropes, crampons, ice tools, etc.). The frame sheet helps distribute weight very evenly across your back and the mesh layer assists with evaporation. I'm actually using this bag as a daily commuter to and from work (8 miles biking RT) because of its volume and versatility. 10/10 would buy again, but make sure you get the grey/blue. In my opinion, the green bag is a Mutant that only a mother could love...

Rated 5 out of 5 by from Great Pack, Feature Rich Just used on a short trip and it served me excellently. I'm a 6'4", kinda broad shouldered guy, and the pack fits great and tightens down perfectly. It makes a great pack for either the beginner or someone that is a little more seasoned. For more details on it, definitely check out the user manual on Osprey's website to learn more about everything it does, but it seems like an incredibly versatile and comfortable pack.

Rated 5 out of 5 by from Amazing service! I purchased the Mutant 38 pack online and quickly discovered that it was too small. Rather than mail it back, I took it to the Moosejaw retail store in Chicago and they returned it for me and ordered the larger size, which arrived at my front door in 3 days.
