Choosing a harness for cragchalk harnesses ropes quickdraws comes down to comfort on long belays, simplicity at the tie-in, and how well it fits your climbing days - gym laps, outdoor routes, or both. The Black Diamond Momentum aims to cover that middle ground, and this specific listing is a used burgundy and red version with a teal belay loop at USD 27.99.
Quick Verdict
For a climber who wants a straightforward, padded all-rounder for indoor walls and single-pitch rock without a lot of extra features, this Momentum configuration makes sense. It offers the classic Momentum layout - foam-padded waist, fixed leg loops, and two molded gear loops - in a unisex cut. The main consideration here is condition and sizing: it's listed as Used and the specific size marking is not clearly visible in the photos, so fit needs careful attention.
Who It Suits
This harness suits newer climbers building time in the gym who also want to get outside, or occasional outdoor climbers who prefer a simple, comfortable harness over a stripped-down alpine model. The unisex design and adjustable waist webbing help dial in fit around layers, while the fixed leg loops joined by elastic risers keep the design uncomplicated for regular top-roping and sport climbing.
It is less suited to someone who needs a highly adjustable or feature-heavy harness for trad, multi-pitch, or ice where more gear loops, adjustable leg loops, or haul-loop details matter. If you need precise sizing documentation before buying, the lack of a clearly visible size mark in this listing is a meaningful factor.
What Stands Out From the Listed Details
- Padded support where it counts: The description highlights a foam-padded waist belt with an adjustable webbing strap, which is the core of the Momentum's comfort for hanging and belaying.
- Clean tie-in and belay setup: Reinforced tie-in points and a front tie-in/belay loop - noted as teal on this burgundy and red body - keep rope and belay device placement familiar and easy to check.
- Simple leg loop design: Dual leg loops connected with elastic risers and a rear elastic strap give a secure, low-fuss fit without extra buckles to manage.
- Essential gear carrying: Two molded gray gear loops are included for organizing quickdraws and carabiners, matching the needs of sport and gym climbing rather than heavy racking.
- Recognizable build cues: Black Diamond logo patch at the front of the waist belt and Momentum naming, with red webbing straps completing the listed colorway.
Meaningful Trade-Offs
Comfort and simplicity are the strengths, but they come with limits. Two gear loops are enough for a sport rack and gym draws, yet they offer less organization than harnesses built for trad. Fixed leg loops also mean you rely on the waist adjustment and elastic for fit - great for weight and simplicity, less flexible if you frequently change layers or need a very specific thigh fit.
The biggest practical trade-off in this listing is buying Used with no clearly visible size marking. You can reference overall harness proportions in the photos, but you won't have a confirmed size label to cross-check against sizing charts. For a safety-critical item like a harness, that uncertainty matters more than it would for other gear. The listed price of USD 27.99 reflects the used condition, which helps if you're looking to keep costs down for a starter setup, but it also means you should weigh cosmetic wear and prior use against your comfort level with secondhand soft goods.
Bottom Line
The Black Diamond Momentum in this burgundy and red, teal-belay-loop version delivers the straightforward, padded design many gym-to-crag climbers want: adjustable waist, fixed legs, reinforced tie-in points, and two molded gear loops.
Black Diamond Momentum Climbing Harness Unisex Red Maroon Rock Gym Climbing

A good reason to choose this specific option is the combination of the Momentum's padded waist belt and simple fixed-leg-loop layout at a listed price of USD 27.99, which fits climbers seeking an uncomplicated harness for indoor and outdoor rock routes. A concrete limitation is that it is listed in Used condition and the size marking is not clearly visible in the photos, so you cannot confirm exact sizing from the listing alone.
If that fit question works for you and you are comfortable with used soft goods, this Momentum offers a familiar, easy-to-use platform for regular gym sessions and single-pitch climbing. If you need documented sizing or more racking capacity, you may want to hold out for a listing with a visible size tag and additional gear loops.
