Long lead time but definitely expected. Super high quality. Fits perfect on the Spiritus LV119. Installed super easy and the tubes feature is exactly what was missing from that plate carrier. Sized perfectly. I wear a medium plate carrier and went with the small/ medium. Great feel and perfect stretch. Love the side stitched nylon Molle feature as well to add pouches too. All around great product. Definitely recommend and multifunctional for plate carriers.
I got the larger size and it works great. Initially it was too big but once I put in the mags and other accessories and put on more than a Tshirt, the fit was perfect. For reference, I am 5’7” and 200lbs. I’m overweight. Thin or athletic guys should get the smaller size.
I'm very impressed with this cummberbund. The quality of material and stitching is top notch. It's comfortable but also rigid. Currently the only elastic cummberbund on the market I could find that also allows you to attach gear via molle cuts.
A bit of a wait, but worth it! Tubes are my preference, but more often than most you get rigid Tegris with tubes, or no flex cordura/nylon that is stiff and digs into in the most awkward places. With Beez you get the perfect set up. Flexibility of elastic, tube lock up and whatever pattern tickles your nuts!
I bought for my spiritus lv-119, in gods plaid. Perfect fit, and stitching looks solid.
The cummerbund is really well made. It holds PMAGs and a radio firmly. I put it on a medium JPC and I’m 6’1”/210#. The three cell is almost too big. If I were any smaller, it wouldn’t fit. Y’all should offer it in a two cell.
Lead times were long, but well worth it. Set up was easy, I’m running an HRT RAC carrier and setup did not require the scarab kit, however I purchased it just in case. Each cell fit 30 round rifle mags with ease, with the laser cut molle on the outside you can attach various other pieces of kit to accommodate your needs. Distractionary devices fit in each cell as well, and provide a snug fit without a struggle to retrieve during operations/ training. This was a great addition to my kit and provided a snug fit to the torso without compromising comfortability. Overall great purchase!
Very solid cummerbund option for the LV119 from Spiritus. I’d been running a setup from AXL but like having some stretch when I’m really working hard in a PC. This fit the bill, has mag pouches that I also use for a radio and zip cuffs and has the tubes system. It’s a win in my book
Only had it a couple weeks so don’t know if it’s long term durability but it seems to be well made (to my civilian eyes) and it fits nicely on my plate carrier. It doesn’t seem to have enough retention to keep a fully loaded mag in the inverted position (pulling the mag out of the pouch downwards instead of upwards) as jumping up and down causes the mags to start to migrate downwards. However I have complete confidence in its ability to retain magazines right way up. Would have been nice if it came with some elastic cordage though, had to scrounge for some in order to mount it to my carrier. Overall I’m happy with my purchase and would recommend it.
Seems to work well, and it's very well made. However I can see this product being a bit large for many users. I am not a small man and the cummerbund tightened as small as can be is still a bit loose. Doesn't have the same adjust-ability as a standard cummerbund.
