The genetics are evident in the Mountainsmith Colfax 25 Backpack. As a small member of the All-Terrain family, this durable daypack has aluminum stays and the Anvil Airway system to keep you comfortable on your way to class or on a long day hike. This durable little number holds up to 25 pounds, and it's your choice whether mix and match, or make all of those pounds come from carbonated adult beverages. A padded interior sleeve holds a 15.4-in laptop for your electronical inclinations, or you can fill the space with a hydration bladder if you want to bring easy-to-sip water with you. When you're only toting a pair of socks, side compression straps eliminate unused volume. Two zippered side pockets provide secure storage for your phone or secret stash of candy. Small enough to fit securely under the seat back in front of you, this daypack gets you and your gear where you need to go.

  • Y-frame dual aluminum stays
  • Anvil Airway perspiration control system
  • 25lb maximum capacity
  • Dual panel access
  • Hydration compatible, reservoir not included
  • Padded interior sleeve, fits most 15.4in laptops

Deceivingly Spacious

At first glance, you'd think this was just your run-of-the-mill daypack/laptop pack. But, you'd be wrong. This bad boy fits my 15 inch Macbook Pro while carrying my rain gear, down jacket, all my cords, a protein shaker, extra pair of pants, undies, socks, beanie, and my toiletries (weekend trip at the parentals). I'm really impressed with the interior padding for my electronics, and it's really great to have a light color on the inside to find those hard to see items. The shoulder straps are thin, but that's a good thing because it makes a form fit on your shoulders, rib cage, and back.
