Petzl Luna Climbing Harness - Women's Review (2026)

A harness built specifically for women

Petzl designs the Luna's waistbelt shape, rise, and the ratio between waistbelt and leg loops specifically for a female body rather than adapting a men's pattern, according to Petzl's own product information. The shell uses polyester and recycled polyester fabric over an EVA and polyurethane frame, with high-modulus polyethylene reinforcement and aluminum hardware. Retailer listings put the harness across four sizes, XS through L, with a padded waistbelt and leg loops meant for the kind of extended standing or hanging comfort that single-pitch cragging and multi-pitch days both demand. Petzl positions the Luna as a step up from its entry-level women's harnesses, aimed at climbers who already know they want to keep climbing regularly rather than trying the sport for the first time.

Sizing and weight by size

According to Petzl's retail partners, the Luna weighs between roughly 365 grams in size XS and 420 grams in size L, with waist measurements running from about 65cm in XS up to 92cm in L, and leg loop ranges sized separately for each. That range covers most adult women, though as with any harness, trying it on or checking a detailed size chart matters more than trusting a general size label like small or medium. The DOUBLEBACK buckles on the waistbelt adjust to fit over different layers, from a light base layer in summer to a bulkier softshell in colder conditions.

Gear loops and hardware for real routes

The Luna carries five gear loops, described by retailers as two rigid loops at the front for quickdraws and cams, two flexible loops toward the rear, and one center rear loop, giving it enough capacity for a moderate trad rack or a full quiver of sport draws. It also includes a single tie-in and belay loop setup along with a haul loop, standard on a harness aimed at multi-pitch and trad climbing rather than pure gym use. The tapered, smooth-seamed construction around the leg loops is meant to reduce chafing on long routes where a harness stays on for hours at a time.

Certification and durability

The Luna carries CE EN 12277 type C certification and UIAA certification, the standard marks for a sit harness rated for rock climbing and mountaineering use, and Petzl backs it with a multi-year guarantee against material and manufacturing defects. Because the harness leans toward multi-pitch and trad use rather than a stripped-down gym design, it runs heavier and costs more than basic women's gym harnesses on the market, which is the trade-off buyers make for the added padding and gear loop capacity. Retailers list it at roughly 85 to 95 US dollars, a mid-range price for a harness built with this much padding and hardware.

Who the Luna fits best

Climbers who split time between the gym, single-pitch cragging and occasional multi-pitch or trad days get the most from the Luna's blend of comfort and gear capacity, especially those who already know a women's specific cut fits them better than a unisex harness. Climbers who only ever climb indoors may find the extra padding and gear loops more than they need for now, and may prefer a lighter, simpler gym harness instead. With a site score of 8.3 out of 10, the Luna stands out as one of the more complete women's harnesses in this price range, especially for climbers planning to keep progressing outdoors.
