prAna Stretch Zion Pants II - Slim Fit Pants for Men Review (2026)

What it is

The Stretch Zion Pants II Slim Fit is prAna's updated take on its popular Zion line, cut with a trimmer, more tapered leg than the classic version. It is built from the brand's ReZion fabric, a blend of 95 percent recycled nylon and 5 percent elastane that gives the pant four-way stretch while keeping the fabric weight low. The slim cut is aimed at climbers and hikers who find the original Zion baggy through the thigh and calf, and who want a pant that also looks reasonable off the wall or trail. It keeps the same general feature set as the standard Zion, just wrapped in a narrower silhouette that tracks closer to the leg through the knee and shin.

Fit and comfort

Because the leg is slimmer than the standard Zion, fit is the main thing to get right before buying. Climbers with average to lean legs generally find the slim cut comfortable through high steps and bridging moves, since there is less loose fabric to catch on holds or rock. Climbers with more muscular thighs, or anyone planning to layer a base layer underneath for cold-weather cragging, should expect it to feel more restrictive than the standard Zion pant. The four-way stretch fabric and the ventilated inseam gusset both help offset the snugger cut by adding give through the crotch and upper leg during big reaches, but they do not fully replace the room the classic fit offers.

Materials and build

The pant uses prAna's ReZion recycled nylon and elastane blend, produced in a Bluesign approved and Fairtrade certified factory, with a PFAS-free durable water repellent finish applied to the fabric. That DWR sheds light rain and resists everyday abrasion from rock and rope without relying on the older PFAS-based treatments that outdoor brands have been phasing out. Built-in UPF 50 plus sun protection is useful for long days at sunny crags. Construction details carried over from the standard Zion include a classic front zip fly with a button closure, back patch pockets, and a side flap utility pocket, along with a snap roll-up tab at the hem for wading through creek crossings on the approach.

On the wall and beyond

For climbing specifically, the slim leg is the main selling point. A trimmer cut means less fabric bunching at the knee during high steps or catching on small holds during technical face moves, which matters more in bouldering and technical sport routes than on easy trad pitches. Off the rock, the pant reads more like a regular pair of trousers than a technical hiking pant, which is why many buyers use it as a daily driver for travel, gym sessions, and casual wear as well as at the crag. The stretch and the ventilated gusset keep it from feeling restrictive during everyday movement, even though the leg itself sits closer to the body than looser hiking pants.

Who should buy it

This pant suits climbers and hikers who already like the Stretch Zion formula but want a narrower leg that looks less baggy and snags less on gear and holds. It is a reasonable single pant for someone who wants one pair that works at the gym, at the crag, and around town, since the slim cut does not read as overtly technical. Climbers with larger thighs or calves, or anyone who regularly layers thermals underneath in colder conditions, should size up or consider the standard-fit Zion pant instead, since the slim version trades room for a cleaner line. Anyone unsure of fit should check prAna's size chart closely before ordering, since slim cuts vary more between brands than relaxed fits do.
