    Elastic cummerbund

    Published by Chandler on Jul 9th 2023

    This cummerbund is perfect for a minimalistic carrier setup with a little bit of added features and securing the carrier down. The elastic feature is great to for the cummerbund to be tight but still have some extra mobility.

    Stands the torture of the desert

    Ive been pretty rough on all my defense mechanisms gear since i got it and i must say whoever they have in charge of quality control deserves a raise. Their gear is not only comfortable but can take a beating, i look forward to their future developments

    Elastic Cummerbund

    Published by MATT B on Sep 3rd 2022

    Very easy to install. ROC buckles are a must. Set once and never have to worry again. Ordered the wrong size and no questions were asked. Got it replaced. Love the fit and feel.

    Very high quality and well thought out. Just discovered this company and this is the first item I've bought. I highly recommend them and will be purchasing more gear from them in the future.

    Review update

    Published by Isaac on Jul 4th 2022

    I wanted to update my review from my original first impressions. I will start by saying DM did listen to my first review with many others and did add different sizing. That's awesome. Material is still holding up great to the hours of range use over the last year. Here's my complaint. The cells are not tight enough to hold 556 mags securely during movement. On two separate occasions I had an Israeli bandage that fits tight in all my other mag pouches fall out. I also lost another full mag on the range from going from prone to standing (I think something from my belt bumped the bottom of the mag). My fix to this was sewing in some material on the back of the cummerbund cell to run their chock cord system. I would like to see that in the future or tighten the cells up a little bit. DM has been improving and changing designs on products over the last year and we appreciate it. They still make great gear but think the design could use some changes.

    4” Elastic Cummerbund

    Published by Morgan Mohr on Apr 26th 2022

    Just got it on my Safelife Defense vest and instantly love having the extra storage. The quick detach is way better than straight Velcro and this cummerbund makes me hate the vest a lot less.
