Arc'teryx Naos 55 on top of Mt. Washington 77 MPH wind
Great pack! Waterproof! I first took it on a overnight trip in the White Mt. National Park in NH. We hiked up the Huntington ravine trail no sweat! Pack stayed tight to body, even on sketchy climbs. (You can lube the suspension if it squeaks) The size is great, you can roll it down for smaller loads or over stuff it to a large load. I fill the bottom with my sleeping bag without a stuff sack. The one problem I had was although it is watertight all my Sh** got wet on my first trip. You see the bag has a thoughtful water bladder holder inside with a removable hole to route your camelback line. With the lid on the open hole stay's dry from most weather. My problem was my bladder leaked and all my stuff was wet! The bag did not leak, until I dumped out all my water it was holding. So it holds water just as well as it keeps it out! So if you need it to carry water for some reason it would work well. Thank God my sleeping bag is a Mt. Hardware Spectra with the waterproof conduit shell, otherwise it would have been a really cold night on the side of MT. Washington.
Bottom line great pack!
