After putting a number of miles on my Manta, I have one gripe with the pack. The stow-on-the-go pole lower attachment is difficult to use. The lower attachment seems to be perfectly aligned to make it almost impossible to fit your poles into the loop, especially if they have baskets. With it tucked in behind the side pocket, you need to reach your left hand back to guide the bottom of the poles in. You need to come down from the top, or up from the bottom, and this eliminates the ability to use your right hand to assist. To me, it feels that this loop is off by ninety degrees. Otherwise, this pack seems rugged and capacious. As with most Osprey packs, the hip pockets could stand to be longer/taller to fit the newer cell phones and spaced further out from the pack. Zipping them closed one-handed is always a chore. A feature they should also use on the Manta are strap pockets, as are found on other Osprey models. On the whole though, this pack is an industry leader.ï»¿ The addition of the AG system to this pack was a key deciding point for me to purchase this pack, and weightier loads disappear on your back.
