Ultralight packs aren't always well-designed or easy to use, driven by the erroneous belief that weight is the only thing that matters. The North Face proves that wrong with the Casimir 32 Backpack. The Casimir is packing smart features like total fit adjustability and panel-loading, but it somehow manages to stay just over two pounds.

  • The North Face Opti-Fit Nano for a perfect fit
  • Size-adjustable men-specific hip belt and harness
  • Comes in 2 torso sizes–S/M and M/L
  • Panel access makes it easy to get to, organize, and balance your gear
  • Tough 70D geo ripstop and polyurethane-coated nylon for weather resistance
  • Multiple pockets for easy organization and quick access
  • Multiple external pockets for quick access to essentials
  • Reflective elements to make you more visible in the evening

This is a light and fast backpack that works extremely well for fastpacking. I used it on the Transfer park loop with no issues. It carried a Marmot Hydrogen bag , Primus ETA Lite with canister and spork. Alpinist bivy, Neo-Air sleeping pad, change of socks, Montane rain jacket, three Mountain House meals, snacks, 2 ltr Platypus and Aquamira drops. Out for three days and two nights "fastpacking" and this pack worked great. Easy adjustments and fit was good. If you have had trouble finding packs to fit, definitely check this one out!

Does this have an internal frame of some sort? If not is the Opti-Fit Nano support sturdy enough to not collapse on itself when the bag is empty?

Howdy, thanks for the question.

The key is actually to measure your torso length, not your height. It's best to have a friend handy as this is rather a difficult maneuver to accomplish solo.
