Osprey has a new line of packs coming out in Spring of 2006; the Stratos series. There are 5 packs in the series (12, 18, 24, 32, 34) named according to their volume. These packs share a similar harness and suspension to Osprey's Atmos series; that is, they have a super-cool (literally) trampoline backpanel and great pockets on either side of the hipbelt. Osprey's AirCore frame is lighter than the AirSpeed from in the Atmos series and the fit seemed a little better as well.
The packs within this series differ from each other in the type of activity they are best suited for. While all are equipped with ice axe loops, some are suited to carrying skis and others better for snow shoes/snow boards. One model, the Stratos 34, is well equipped to carry all the above. All of the packs in this series are designed for fast moving activities from trail running to alpine skiing to climbing.
They all include side water bottle pockets and hydration compatibility. Most of the series are panel loaders with heavy zippers; the exception is the Stratos 32, a top lidded, top loader with panel access along the left side.
