2. Setup and Fitting
Proper fitting of your climbing harness is crucial for safety and comfort. The Momentum harness features a pre-threaded Speed Adjust waistbelt buckle and TrakFIT leg loops for easy adjustment.
2.1. Waistbelt Adjustment
The Speed Adjust waistbelt buckle is designed for quick and secure tightening. Ensure the waistbelt is positioned high on your waist, above the hip bones, for optimal safety and comfort. The webbing should pass through the buckle correctly, with no twists, and be snug enough that you cannot pull it down over your hips.
2.2. Leg Loop Adjustment
The TrakFIT leg loops allow for quick and easy adjustment to accommodate different layering configurations or body types. Adjust the leg loops so they are snug but not restrictive, allowing for full range of motion. Ensure the elastic risers connecting the leg loops to the waistbelt are not twisted.

3. Operating the Harness
The Momentum harness is designed for various climbing disciplines, offering comfort and functionality.
3.1. Attaching to the Rope
Always tie into the harness using a figure-eight follow-through knot, passing through both the waistbelt and leg loop tie-in points. Ensure the knot is properly dressed and tightened, with a sufficient tail. Double-check your knot and your partner's knot before every climb.
3.2. Using Gear Loops
The harness features four pressure-molded gear loops, strategically placed for easy access to quickdraws, cams, and other climbing equipment. Distribute your gear evenly to maintain balance and comfort.

3.3. Belaying and Rappelling
The durable belay loop is designed to withstand the forces of belaying and rappelling. Always use a locking carabiner to attach your belay device to the belay loop. Ensure all connections are secure and properly locked before engaging in belay or rappel operations.

4. Maintenance
Proper maintenance extends the life of your harness and ensures continued safety.
4.1. Cleaning
The harness should be cleaned by hand washing only. Use mild soap and lukewarm water. Rinse thoroughly to remove all soap residue. Do not use harsh chemicals, bleach, or machine wash, as this can degrade the materials.
4.2. Drying
Allow the harness to air dry completely in a cool, shaded area away from direct sunlight or heat sources. Do not tumble dry or use artificial heat, as this can damage the webbing and padding.
4.3. Storage
Store your harness in a cool, dry, dark place, away from chemicals, sharp objects, and extreme temperatures. Keep it in its mesh storage bag to protect it from dust and abrasion.
5. Troubleshooting
If you encounter any issues with your harness, perform a thorough visual inspection. Look for:
- Cuts, abrasions, or fraying on webbing or stitching.
- Deformation, cracks, or corrosion on metal buckles or gear loops.
- Damage to the belay loop or tie-in points.
If any damage is found, or if you have doubts about the harness's integrity, discontinue use immediately and contact BLACK DIAMOND customer support or a qualified climbing professional for assessment. Never attempt to repair a damaged harness yourself.
