The Exos 46 Backpack by Osprey is a super lightweight pack for weekend and thru hiking trips out in the backcountry.  The Exos 46 has an AirSpeed suspension that consists of an aluminum frame with a 3D tensioned mesh backpanel that provides excellent ventilation and a unifrom body contact with no hot spots.  The BioStretch harness and hipbelt gives you incredible fit and comfort for all sizes.

Dual side mesh pockets with InsideOut compression allow you to tension and secure your load easily when the pockets are in use. The Exos features an internal sewn-in backpanel sleeve with clip attachment to accommodate up to three liters of hydration. At the top of both sides of the pack you will find H20 icons marking the routing points for your hydration tube.

This is a great pack for shorter trips.

What’s in your pack? Backpacking gear list 2: The ultralight backpacker
"Ultralight backpacking means quite a few different things to quite a few different people. Some take it to extremes, striking out into the wilderness without a tent or rain gear. Increasingly, though, we come across folks who are simply looking to travel greater distances in a day than is possible with a heavy pack, or who are looking to reduce the strain on their hips and knees by shaving pounds from their normal backpacking gear..."

What’s in MY pack? Backpacking gear lists from a Great Smoky Mountains overnighter
"Ever since we published a series of backpacking gear lists this spring (an ultralight backpacking gear list, a traditional backpacking gear list and a beginner’s backpacking gear list) several blog readers have contacted me to ask which of those items I personally carry. After all, it’s one thing to compile lists of suggested backpacking gear, and another thing entirely to disclose exactly what I take on the trail. Well, what better way to follow up those gear lists, and answer that question, than with another gear list?"

Comments about Osprey Exos 46 Lightweight Backpack:

This entire line caters to the ultralight enthusiast. I have used this on many long hikes and have enjoyed all the features it offers. The shoulder straps may dig in to you if you have too much weight. Keep your pack weight below 25lbs and your going to have a blast and hike far.

      These are the size of the frame. In order for a pack to fit correctly, the internal frame should be properly fitted to your torso. We usually do a pack fitting in our stores for customers that aren't sure, but if you're not near a store you can call our customer service and they will help you figure out which size Osprey frame is appropriate for you. Unfortunately, it's not quite as simple as your height!
