You might be used to packing heavy including every possible piece of gear you think you may need but with the Mountainsmith Scream 25 Backpack you can break free from your fears. Weighing right around a pound and fitting over 1500 cubic inches of gear the Scream 25 has more than enough room for lunch layers water and rainshell and yet doesn't add unnecessary pounds to your shoulders or tempt you with extra space for frivolous weight. You can use it alone during lightweight day hikes or stuff it into its own lid pocket and carry it along on backpacking trips for summit pushes and side trips from basecamp. The Scream rolls into its own top panel so its not only a breeze to pack but also doubles as a pillow when you've brought it along for lengthy trips.
