Review: Zenbivy UL Dirtbed

Despite its ubiquity in marketing and advertising—and the concomitant efficacy at selling products—hyperbole is anathema to good writing. Which is why I’ve always mocked the use of the term “sleep system.” System, really? It’s a freakin’ bag & pad, bro, not an “interdependent assemblage of parts forming a complex or unified whole.” But after trying out the Zenbivy UL Dirtbed Bundle ($640), I may have to reevaluate my pedantic position. This is indeed much more than the usual mummy-and-mattress bedroll. Yep, the Dirtbed, like most Zenbivy models, redefines the sleeping bag, with its multi-item structure specifically designed to make you warmer and more comfortable, resulting in a long, restful night’s sleep.

It starts with the mattress, around the head of which is wrapped a sheet, into which is clipped a quilt, which can be configured a multitude of ways, depending on temperature and constriction tolerance. A pillow stuffs under the oversize head pocket, complete with a separate pillowcase, and a dry sack keeps everything clean and dry during transport. The pillowcase and sheet can be cleaned between trips, preventing the dreaded perma-funk, and the pillow can be deflated for compact storage in your pack. All in all, it’s a superior sleep system—there, I said it—that may make you reevaluate your own assumptions—namely, that all sleeping bags are created equal.
