REI-OUTLET offers the Mountain Hardwear Kalispell 15" Notebook Backpack in four colors (Orb Blue pictured) for $41.93. With $5.99 for shipping, that's the lowest total price we could find by $3, although we saw it for $2 less yesterday (since expired). Sales tax is added where applicable. It features a padded back panel and shoulder straps, hydration/laptop sleeve, side compression straps, sternum strap, and more.
