Jason H.wrote a review of Osprey Packs Stratos 24 Backpack - 1300-1700cu in on June 2, 2010
Finally got to use this pack on a few warm weather hikes and it performed flawlessly. I am a bigger guy so have a propensity to perspire and this combined with the proper clothing kept me amazingly dry. As stated in another review, the large suited me well, being 6 foot with a large chest. The AirCore suspension does take away from the interior space when using the internal hydration sleeve but you can still get everything you need and more for a day hike included using the external pocket and compression straps, and that is with 72 oz hydration. I have not yet tried placing the hydration in the AirCore suspension on a hike but tried the pack on with a full 72 oz and seemed it may hinder the ventilation, but I cannot confirm, nor deny this. Overall, I would highly recommend this pack.
