The Brown Buffalo : ConcealPack™ 21L : Black Multicam®

The ConcealPack® 21L was born out of real-world necessity on a trip from California to Australia through Tokyo's crowded commuter lines.

Refined with feedback from active duty military, EOD specialists, law enforcement, and private security professionals. Every stitch is intentional. Designed by a founder with 25+ years at Nike, The North Face, and Burton.

The ConcealPack isn’t defined by one user group; it’s shaped by everyone who has trusted it, from active duty operators to riders, travelers, designers, and everyday professionals who value quiet capability. Designed and Developed The Brown Buffalo's Costa Mesa workshop, surrounded by a community of independent thinkers and craftspeople, this pack carries the collective experience of people who understand the importance of equipment that simply works.

A question we hear often: “What are the buckles and D-rings on the front for on the shoulder straps?”

We don’t advertise these heavily, but they exist for a reason. Over the years, we’ve incorporated subtle functionality requested by operators in the military, law enforcement, and EOD communities. Those who need them know exactly what they’re for, everyone else just gets clean hardware that integrates seamlessly into the silhouette.
