Very good
Superlight ventilated mochila. , enough room and pockets, very comfortable, shield against light rain; well balanced. This product is built for comfort, also is very specialized mochila for a long day trip adventure or a weekend.

Great for Light Stuff
Pack is great. Used it for hut trip in Patagonia, would have been perfect except that my camera gear pushed the weight limit a little over the limit. This is a very well thought out design, especially the hip pockets and gear attachments. Just keep in mind that this is a pack for light journeys, the harness/supports are just not meant for heavy gear.

Amazing technology
In my opinion, Osprey is the best maker of backpacks. They are very well designed and you will feel this immediately after loading your backpack and putting it on. The Exos 34 is ideal for day trips with small to medium loads. The straps, buckles, and zippers are very convenient. I did not test it in the rain; however, from my previous experience I know that you always need to carry even the simplest rain poncho to protect your backpack and its contents. Please note that they are 3 sizes of each Exos backpack: Small, Medium, and Large. You need to consult the measuring chart before placing an order.

Wow! Lightweight and ready for fastpacking
I have to admit, I drooled when I received this pack. It is loaded with features and fits perfectly. This one is the best for lightweight fast travel. The outside pockets make getting at small items very do-able, as do the hipbelt pockets. I recommend this for lightweight overnights and weekends, as well as to trail runners.

Solid pack
The Exos34 is a great day or overnight pack. It's light and very comfortable, with good ventilation/air flow. The straps are a bit thin, but I suppose that's part of the reason it is light. Overall a nice backpack.
