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

Who this harness fits

The Luna is Petzl's dedicated women's harness, shaped with a waistbelt rise and waist-to-leg-loop ratio built around a typical women's body rather than a unisex cut adjusted down in size. Petzl positions it for single pitch cragging, multi-pitch routes and trad climbing, which shows in the five gear loops and the padded comfort meant to hold up through long belays and hanging stances. The coral red colorway is simply a finish option within the standard Luna line rather than a different model, so climbers choosing it are getting the same fit and feature set as other Luna colors, just easier to spot at a busy crag or gym. Climbers who want the lightest possible sport-only harness with minimal padding may prefer a more stripped down model, since the Luna's comfort features add some bulk and weight.

Fit, sizing and gear loops explained

Petzl and retailer listings put the Luna in four sizes, XS through L, with the size Small fitting a waist of about 23.5 to 28 inches and a leg circumference of 18.5 to 22.5 inches, the Medium fitting a 26.5 to 32 inch waist with a 20.5 to 24.5 inch leg, and the Large fitting a 29 to 35 inch waist with a 22.5 to 26.5 inch leg. Weight ranges from about 365 grams in the smallest size up to 420 grams in the largest, reflecting the extra webbing and padding needed for bigger sizes. The harness carries CE EN 12277 type C and UIAA certification, the standard safety ratings for sport and trad harnesses, and is built from a mix of polyester, including 100 percent recycled polyester, along with EVA foam, polyurethane, high-modulus polyethylene and aluminum hardware. Five gear loops give room for a mixed sport and light trad rack.

Using it day to day on routes

Petzl markets the Luna's breathable materials as a comfort feature for long days, which matters on multi-pitch routes where you are wearing the harness for hours rather than a single pitch. The women-specific rise and hip shape is the main practical difference climbers notice compared with a unisex harness sized down, since it is meant to avoid the waistbelt riding up or the leg loops feeling misaligned on a body with a narrower waist relative to hip width. Five gear loops spread the rack out reasonably well for a day of mixed sport and trad leading, though climbers carrying a full double rack of cams and slings for longer trad routes may still want a harness with more dedicated loop capacity. The padding that makes hanging belays comfortable does add some bulk compared with a minimalist sport harness.

How it stacks up against other women's harnesses

Against the Black Diamond Momentum in its women's version, the Luna leans more toward multi-pitch and trad comfort with its five gear loops and dedicated rise, while the Momentum is generally positioned as an all-around gym-to-crag harness with trakFIT adjustable leg loops for quick layering changes. Against the Petzl Corax LT in its women's cut, the Corax LT is built lighter for movement-focused sport and gym days, while the Luna carries more padding suited to hanging belays and longer routes. Climbers who split time between the gym and short sport routes may prefer the lighter Corax LT, while those doing regular multi-pitch or trad days will likely appreciate the Luna's extra comfort and loop capacity more.

Bottom line

The Luna is a strong choice for women climbing multi-pitch, trad or long sport routes who want a harness shaped specifically for a narrower waist and wider hip ratio, backed by CE and UIAA certification and Petzl's reputation for climbing hardware. It earns our score of 8.6 out of 10, with build and materials rated highest thanks to the breathable padding and five gear loop layout. Climbers who want the lightest possible harness for short gym sessions or minimalist sport days should look at a lighter model instead, since the comfort padding that makes the Luna good for long routes adds weight that is unnecessary for quick pitches.
