Rugged Pack for Everyday & Everywhere

A favorite of hikers and travelers for the past 35 years, the Mountainsmith Day pack is now more durable and versatile than ever. Recently updated with 610d Cordura HP fabric and a bright yellow 210d nylon liner, it can be used as a hiking pack, messenger bag, low-key briefcase, carry-on, diaper bag—and really, just about anything you can imagine. It features ridged EVA back-panel padding, removable shoulder straps, and a tuck-away waistbelt complete with a smartphone-compatible pocket. Along with a zippered front-panel pocket with a key clip, you’ll find a hanging interior pocket, a padded tablet sleeve, and a headphone port. Bar-tack reinforcements, YKK zippers, and 3M reflective cord complete the package.

Note: At checkout, you’ll have your choice of color between Asphalt Gray, Classic Red, Deep Blue, Heritage Black, Lichen, and Otter Brown.

About Mountainsmith

Founded in 1979 by legendary outdoorsman Patrick Smith, Mountainsmith started out making extremely durable gear built to withstand the rigors of Colorado’s Rocky Mountains. This led to the development of the world’s first fully rigid backcountry ski sled, and later, the iconic lumbar waist pack. Today, the company produces a full line of outdoor products (including trekking poles, tents, and sleeping bags), at the heart of which are its technical backpacks, recognized for their comfort, stability, value, and performance.
