Mountainsmith - Apex 80

  • Sale
  • Regular price $223.95

There are times when we crave more out of our backcountry adventures, and the Apex 80 is there to provide. An expandable front pocket as well as durable XL stretch mesh pockets provide ample storage and easy access to that extra gear you can’t live without. Our signature Tuning fork hip belt was designed to supply much needed comfort on our larger packs, naturally cupping the iliac crest of the hip bone for a more dynamic fit and superior load transfer. Lightweight & comfortable molded EVA foam pads on the back panel create a no contact breezeway for improved airflow when you need it most. On trail, the advanced tubular aluminum frame reduces weight without sacrificing load-bearing performance.

Some trips require more room, more versatility, and more comfort, the Apex 80 is here to deliver. A spacious top-lid and U-shaped zipper make it easy to access your essentials on the go whether you’re at your campsite or lunch rock. Weather protected stretch mesh hip belt pockets make it easy to stash snacks & electronics without losing a stride. From winter sleeping bags to camera gear to a little extra beer, the Apex 80 has room for it all.

All Mountainsmith products come with the Forged for Life Guarantee, the official Mountainsmith lifetime warranty.
