Vertice

Zpacks designs the Vertice rain pants for ounce-counters who need dependable storm protection without hauling a half-pound shell in their pack. Built around a proprietary three-layer waterproof-breathable laminate with a gossamer 7-denier face fabric, these bottoms shed unnecessary bulk by omitting cargo pockets, belt loops, and heavy hardware. The result is an exceptionally airy pant aimed squarely at long-distance backpackers and thru-hikers who walk through persistent rain but spend most sunny miles carrying their wet-weather gear.

On the trail, the textile sheds soaking precipitation while offering respectable vapor transfer compared to traditional non-breathable silnylon chaps or budget PU coatings. Moisture management is surprisingly capable when pushing uphill, though the athletic cut and absence of mechanical thigh vents mean sweat will inevitably accumulate during high-output efforts in warm rain. The wispy face fabric also demands respect. It glides comfortably over bare skin thanks to the tricot backer, but bushwhacking, rough granite scrambles, or thorny blowdowns will quickly abrade or puncture the shell.

Against mainstream competitors like the Outdoor Research Helium or Patagonia Torrentshell, the Vertice offers zero everyday conveniences—you get no hand pockets, no full-length side zips, and no heavy-duty scuff guards. However, compared to rival ultralight options like the Montbell Versalite, the three-layer construction provides superior next-to-skin comfort by resisting that clingy, clammy feeling when worn over shorts. They are an uncompromising, specialized tool best reserved for disciplined hikers on maintained trail systems.
