When shopping for climbing harnesses, ropes & quickdraws, the harness choice often comes down to a practical tension: pay less for a used harness with clearly described climbing features, or pay more for a New, Medium harness aimed at adult rock climbing. Black Diamond Momentum and Edelrid Jay II take those two paths, so the right pick depends on price, condition, size, and intended setting.
Quick verdict
The Black Diamond Momentum Climbing Harness is the clearer choice when the lower listed price and explicit indoor-gym and outdoor-rock-route wording matter most. Its description also calls out a padded waist belt, connected dual leg loops, a front tie-in/belay loop, and two molded gear loops. The trade-off is its Used condition.
The Edelrid Jay II Adult Rock Climbing Harness fits shoppers who specifically want the listed Medium size and New condition. Its title and description focus on adult outdoor rock climbing. The trade-off is price: the two harnesses are $17.01 apart.
Side-by-side comparison
| Harness | Listed price | Condition | Key listed details |
|---|---|---|---|
| Black Diamond Momentum | $27.99 | Used | Padded waist belt, connected dual leg loops, front tie-in/belay loop, two molded gear loops; indoor gym and outdoor rock routes |
| Edelrid Jay II | $45.00 | New | Adult rock-climbing harness, Medium size, Blue/Aqua colorway |
The price difference is straightforward: Black Diamond is listed at $27.99, while Edelrid is listed at $45.00. That makes condition and the Medium size just as important as the dollar amount when narrowing the choice.
Where each harness wins
- Black Diamond Momentum wins for indoor gym and outdoor rock-route wording. It is also the choice for shoppers who want the lower listed price and clearly described gear-carrying features, including two molded gear loops.
- Edelrid Jay II wins for the New-and-Medium combination. That pairing is stated directly in the product title, making it the more targeted pick for someone shopping for an adult Medium harness in New condition.
Product notes
Black Diamond Momentum Climbing Harness
Black Diamond Momentum makes sense for a shopper who wants a lower-priced harness with a clearly described range of use. The description specifically names indoor gym climbing and outdoor rock routes, then adds practical details: a foam-padded waist belt, connected dual leg loops, a front tie-in/belay loop, and two molded gear loops for quickdraws, carabiners, or other climbing hardware. Those details give the harness a defined feature profile for the listed activities. The main limitation is condition: this harness is listed as Used, so it is not the match for someone whose priority is buying New. At $27.99, it is the lower-cost route between the two choices.
Edelrid Jay II Adult Rock Climbing Harness
Edelrid Jay II is the direct match for someone seeking the title's Medium size and New condition in an adult rock-climbing harness. The product description places it in outdoor sports and rock climbing, while the title identifies the Blue/Aqua colorway. Those details make the harness worth choosing when size and condition are the primary filters rather than the lowest price. The concrete limitation is the listed cost: $45.00, or $17.01 above Black Diamond. The description also mentions durable materials and support for outdoor adventures, but those phrases do not establish a performance ranking against the Momentum. Choose Jay II for the New/Medium combination, accepting the higher listed price.
Final choice by use case
- For indoor gym climbing: Choose Black Diamond Momentum, because indoor gym use is explicitly named and the listed price is lower. Its Used condition remains part of the decision.
- For the listed Medium size: Choose Edelrid Jay II, whose title specifies Medium and New condition.
- For outdoor rock-route wording plus gear-loop detail: Choose Black Diamond Momentum, with its stated outdoor rock-route use and two molded gear loops.
- For New condition in an adult rock-climbing harness: Choose Edelrid Jay II. The higher $45.00 price is the clearest trade-off.
