Osprey Exos 46 Reviews:


No other bag needed for me. Went over to the ultra light side of backpacking (not sure why I never started there) and this bag helped. I won't use another bag again. Plenty of space and feels amazing. A couple of features I don't need, like the trekking pole loop, but Osprey made it so that kind of stuff is easily removed without damaging the the bag. I'll have this one for a while.

Great backpack

This is a fantastic bag. The light polymer frame provides the exact amount of support you would want with such a light bag. Handles loads up to thirty pounds just fine for me. Get this if you want an very light bag with all the bells and whistles of a normal heavier bag.

I'd buy this apck again!

This pack is very comfortable, enough room for a lightweight backpacker, great suspension. It fits my 5"10 frame very well. Just be sure you have lightweight and compressable gear. This pack will carry 30 lbs just fine.
