How to Fit the BDS QR Low Pro Cummerbund Kit

Quick Answer

Thread the MOLLE straps through your plate carrier's webbing, snap the FIRSTSPEAR TUBES® together, then adjust the cummerbund tension so it sits snug but not restrictive.

Step-by-Step Installation

1. 1. Remove the Old Cummerbund: Unbuckle or unthread your existing cummerbund from the plate carrier. Keep the carrier's front and back plates aligned—don't let the carrier sag while you work. Common mistake: pulling the old cummerbund out without noting the strap routing. Take a photo first so you can mirror the pattern.
2. 2. Thread the MOLLE Straps: Start at the rear plate bag. Weave each MOLLE strap on the BDS cummerbund through the corresponding horizontal webbing slot on the carrier, from the inside out. Pull the strap through until the cummerbund's fabric sits flush against the carrier. Don't skip rows—using all available MOLLE slots distributes load evenly and prevents the cummerbund from shifting during movement.
3. 3. Attach the Front TUBES® Buckles: Snap the FIRSTSPEAR TUBES® male ends (on the cummerbund) into the female receivers that are either sewn onto your carrier's front plate bag or attached via adapter straps. Ensure the buckle clicks fully—TUBES® are designed to be audible when locked. If the TUBES® don't align with your carrier's attachment points, use the included webbing loops to create a new mounting point. Never force the buckle; it should seat without extra pressure.
4. 4. Adjust Tension and Length: With the carrier on (or on a test dummy), tighten the cummerbund by pulling the adjustment straps at the sides. The cummerbund should be snug enough that it doesn't slide when you twist, but loose enough to allow deep breathing and arm movement. Over-tightening restricts chest expansion and can cause the carrier to ride up. A good test: you should be able to slide two fingers between the cummerbund and your rib cage.
5. 5. Secure Loose Straps: Tuck any excess MOLLE strap length under the cummerbund or use a strap keeper (not included) to prevent snagging. Ensure the TUBES® release tabs face outward and are unobstructed by pouches or gear. Loose straps can catch on door frames or vehicle seats during tactical movement. A quick tuck or tape-down avoids a dangerous snag.
