Choosing among climbing harnesses, ropes & quickdraws gets difficult when the real question is narrower: do you want a harness named for adult rock climbing, or one paired with a locking carabiner and broader stated user wording? For this matchup, decide by activity first, then the listed size or weight boundary; the price gap comes after those basics.
Quick verdict
Edelrid Jay II is the direct match for adult rock climbing. The Zip Line/Climbing Harness is the alternative when a locking carabiner and its stated user boundary matter. The decision turns on activity, sizing or weight language, and whether the $28.05 price gap outweighs the different package framing.

Where each product wins
Edelrid Jay II wins for adult outdoor rock climbing. Its adult rock-climbing wording gives it the more direct activity match in this head-to-head, especially for shoppers choosing around that named use.
Zip Line/Climbing Harness wins when a locking carabiner should be part of the purchase. The 4-inch hardware is called out in the product title, making that package detail central to the decision. That is a concrete distinction, not a claim that one harness is technically superior.
Product notes
Edelrid Jay II Adult Rock Climbing Harness
The listed Medium, Blue/Aqua version gives a shopper a defined size and color reference. That makes Edelrid Jay II a sensible pick when those details match the intended setup. The main limitation is the Medium designation itself: size suitability must carry real weight in the decision. The adult designation is another concrete part of the format, so the intended user should align with that wording. Choose it when a specifically sized, adult-labeled harness fits the plan. Its New condition is clear, but that label does not resolve the sizing question; Medium remains the practical detail to prioritize before choosing.
Zip Line/Climbing Harness with a 4-inch Locking Carabiner
The Zip Line/Climbing Harness with a 4-inch Locking Carabiner is easier to narrow down when the intended user matches its stated age language: children 8 and above and adults. That makes it a concrete choice for a household comparing an adult user with a child user. Its limitation is the stated 220-lb maximum weight, which should remain part of the selection decision. The steel carabiner is accompanied by 16 kN and 23 kN figures; treat those as raw specifications rather than a basis for ranking it against Edelrid. Choose it when the age wording fits the plan and the weight boundary is acceptable.
Final choice by use case
- Adult outdoor rock climbing: Pick Edelrid Jay II. Its named use is the more direct match for that activity.
- A zip-line setup: Pick the Zip Line/Climbing Harness, whose title is written around that use and a locking carabiner.
- When price is decisive: The $28.05 gap points to the $16.95 harness, while the Edelrid Jay II is listed at $45.
The short version: Edelrid is the activity-led choice; the Zip Line/Climbing Harness is the price-and-package-led choice. Keep the listed Medium size and 220-lb boundary in view before making the final call.
