Our Verdict

Black Diamond has rebranded this harness as the Women's Momentum (it used to be the Primrose), but they kept all of the things that we loved about the old version. The waistbelt has a lot of padding for all-day comfort, and it has the same speed adjust buckles and trakFIT leg loops from the older version. The Momentum is a great all-around model, fit for first-time users and seasoned climbers, alike. It's comfortable to hang in and has easy-to-clip rigid gear loops. Best of all, it only costs $55. If you are looking for a great all-around harness that will perform well from trad to sport, this is a great purchase.

Our Analysis and Test Results

The Momentum is made with BD's Dual Core construction. They use two bands of webbing on the outside of the 3.5-inch waistbelt, with a foam insert in the center for padding and comfort. The legs have a trakFIT adjustment system, which uses a sliding adjuster to change the size of the leg loop, as opposed to a buckle system. According to Black Diamond, this gives you the "adjustability of a buckle but the security of a fixed leg system." It has four rigid, plastic coated gear loops and a rear haul loop.

Performance Comparison


The latest version of this harness is comfortable  versatile  and very affordable  and we've given it our Best Buy award once again.

Standing Comfort


With a wide, 3.5 inch waistbelt, the Momentum is one of the most comfortable harnesses to hang around in, but it doesn't have the best breathability.


This waistbelt is softer than some of the more uncomfortable harnesses, like the Mad Rock Venus, but the thick padding doesn't breathe so well. If you plan on climbing in tropical climates, or anywhere warm really, then look for something a little thinner, like the Black Diamond Solution, or something that has an has an open-back mesh design, like the Mammut Zephir. The Momentum is also a little bulkier than the Zephir or Solution; you might forget you are wearing those models when belaying or hiking with them on. It's not quite as comfortable as our Editors' Choice winning Camp Supernova either, but overall this harness does a good job of finding the sweet spot between a padded harness that won't make your toes go numb and something that's not too bulky and can be left on all day.

While the padding around the waist and legs make this harness comfortable to hang in  it doesn't have the best ventilation and we did feel hotter in this model during the summer months.

Hanging Comfort


Here is where that extra padding on the Momentum comes in handy — this was one of the most comfortable models to hang in, beat out only by the Misty Mountain Silhouette, our Top Pick for Trad Climbing.


This harness manages to be padded and lightweight, which is almost a revelation these days. Manufacturers want to have lighter and lighter products and often do so at the sacrifice of comfort or durability. The Momentum has a lot of padding and it even weighs half an ounce less than the Black Diamond Solution and Arc'teryx FL-355! This is great for anyone who climbs multi-pitch routes or hang dogs a lot, and even for those who have to belay someone who hang dogs a lot.

Our testers found this harness comfortable to hang in  whether working out the beta on a sport climb or on long multi-pitch routes.

Discipline-Specific Features


This harness fits the bill quite nicely for an all-around harness. The speed-adjust buckle is easy to tighten, and you don't have to worry about doubling back the waistbelt every time you put it on. (An older version of this harness had a traditional, fold-back waist buckle, but that type of buckle seems to have finally bit the dust — all of the harnesses in this review have speed adjust/pre-threaded waistbelt buckles.) The gear loops are encased in hard plastic, leaving them rigid and standing out from the side of the harness. This makes them very easy to clip gear to and unclip gear from, though they are not as comfortable when wearing your pack and harness at the same time. The gear loops are appropriately positioned for easy reach to the front and back loops, unlike the Petzl Luna and Selena models, which have frustratingly far away rear gear loops. This harness also has a "real" haul loop (and not just a piece of dental floss flimsily stitched on) which is handy if you are trailing a haul line up a multi-pitch route. All told it is comfortable enough for a long day out but not too bulky to sport climb in.

The gear loops are rigid and stick out from the sides of the waistbelt for easy clipping and unclipping. There's also a haul loop and detachable leg loops should you need them.

Mobility


While not quite as mobile as the ultra-light harnesses out there, our testers were still able to climb with ease in this harness in everything from techy face climbs, to chimneys, to overhanging sport routes.


The waistbelt does not have any uncomfortable pressure points and fits snugly and securely high on the body; the adjustable legs also have elastic in them, which helps give you unencumbered movement.

We liked that the adjustable legs still had elastic in them  which helps give you great mobility in the legs.

Versatility


The Momentum is a great all-around harness that works well in most climbing applications. The comfortable waistbelt and easy to clip rigid gear loops make loading the harness with gear for multi-pitch trad climbs just as easy as racking up for a single pitch sport climb.


It has a sturdy rear haul loop, unlike the Mammut models which have only a p-cord style loop, so you can clip your tag line or water bottle to it without worrying that the weight of it is going to rip it out. The one feature it lacks is a loop for ice tool holders, so it will not cross-over to winter use as easily as the Camp Supernova or Arc'teryx AR-385a.

If you like to clip bolts one day and jam cracks the next  but don't see yourself climbing ice anytime soon  this harness is a great choice.

Adjustability


Black Diamond's trakFIT leg loop system is a unique method of adjusting the size of the loops. Instead of a threaded buckle closure, there is a sliding buckle that tightens or loosens the leg loop, which still has some elastic for stretch and mobility. This system offers more adjustability than a pure elastic system alone, but not as much as a traditional buckle closure.


The plastic slider moves easily around the leg loop to adjust the size quickly and effortlessly. We like that it's so light and that there's not a ton of extra webbing flapping around your legs. However, it only gives you about 2 inches of play, which isn't as much as the 5-7 inches most other adjustable legs loops provide. If you fall within the size range than BD has made the leg loops in, this gives you the ability to wear this harness over various bottoms, from thin leggings at the gym one day to heavier pants outside the next. If your thighs are a little larger though (relative to your waist size), then you'll want to stick to a harness with fully adjustable legs, like the Edelrid Jayne II.

Best Applications


This is a great all-around harness or first harness. It works well in the gym, at sport crags or on multi-pitch climbs. It is comfortable and easy to wear for most applications, but it doesn't have any ice clipper slots, so if you think you will be swinging some tools in your future then the Black Diamond Technician, Camp Supernova, or Arc'teryx AR-385 are a better choice.

This is a great harness for a variety of uses and climbers  from sport to trad  and beginner to experts alike. Best of all  you won't blow your entire budget on this one purchase.

Value


This is one of the best values our there for women's harness. The Mammut Ophira costs $50 but doesn't have adjustable legs or a haul line, so we think the extra $5 is worth it for the added convenience and versatility. The Mad Rock Venus also retails for $50 but is not nearly as comfortable as the Momentum. It's durable enough to last you for years and versatile enough to be used for almost anything, increasing its worth, which is why we've given it our Best Buy award. To further maximize your dollars, you can buy the package, with includes this harness, a chalk bag and a bag of chalk, and a belay device with a locking carabiner, for a total of $100. This is an excellent buy for someone just getting started in the sport of climbing.

Conclusion


The Momentum (and formerly Primrose) harness is a ubiquitous sight at crags and gyms all across the country for a reason. It's affordable and comfortable, which is not always an easy feat for a manufacturer. Although it's deemed an "entry level" harness, we know many expert climbers who use it for those very reasons as well. While we prefer the Camp Supernova as a high-end all-around harness, and BD's Solution for sport-specific applications, the Momentum is a good bet for any climber.
