Micro Fight Back Strap

Maximum purchase 2
Color None Selected Required

It's pretty simple: if you have a Micro Fight Chest Rig, you're going to need this. The Back Strap provides the retention necessary to keep the Chassis close to your body. The back strap attaches to the lower buckles on your Micro Fight Chest Rig and wraps around your lower back. 

This strap can also be used as a sling if you wish to carry your Micro Fight in a cross-body configuration as a "Go Bag." The Micro Fight Back Strap has a maximum adjustment of 36 inches and a minimum adjustment of 8 inches. 

 NOTE: The BACK STRAP is part of the Micro Fight Chest Rig System. This item does not include the chassis, shoulder straps, magazine inserts, or any other accessories. The BACK STRAP is a necessary component of the Micro Fight Chest Rig System when running as a stand-alone system and highly suggested on a plate carrier.

Back strap
Written by Andrew Perera on Dec 17th 2020

As with their chest rigs and plate carriers, their accessories are well made and reliable.

First piece to starting a chest rig. Really awesome material and quality, fast shipping. Love the free stickers too.

Get this one, it works and keeps everything in place. Plenty of adjustment for even they most "tactical" of operators. Yes, even for those midnight basement larping sessions. 10/10

High quality piece of kit. Keeps everything else in place.

Back strap
Written by Cesar garcia on Jul 29th 2020

The back strap looks and feels like it’s made out of quality materials. I’m glad it was worth the wait, and boy did I wait. After creeper-status stalking of the website for stock updates, I was finally able to snag one. It completed my chest rig and I’m happy with it. I’m a patrol officer and rifle sharpshooter that used to snap on a leg rig for my two AR mags and 2 pistol mags, but that rig slowed me down when I had to sprint between cover. The chest rig gives me more mobility and agility. My one improvement for the back strap, specifically, would be an addition of a quick release buckle that would allow me to loosen and tighten the back strap quickly. A buckle similar to one used by Frank Proctor’s rifle sling would make this perfect. That would allow me to throw it over any vest or clothes I may have on and cinch it down quickly.

Great quality!

Hard to screw this one up
Written by John on Jul 15th 2020

It may seem difficult to screw up length of webbing with a couple sliders and buckles, but it's surprisingly common. Spiritus Systems did it right. High quality materials and components, and generous length and range of adjustment. Not sure if I'll actually need it on my chest rig, since they designed the harness system so well, but I'm glad I have it in case I need it.

Exactly As Described
Written by Josh D on Apr 19th 2020

The back strap is what it is and Spiritus' description pretty much nails it. One thing the description lacks is the amount of adjustment and there is plenty of it. Me being a smaller guy, I am always concerned gear will run too big. The Spiritus backstrap has me covered, for you bigger guys - there is more than enough adjustment for you too!

Works Great

does exactly what you'd expect it to do and does it very well!

Back Strap
Written by William Rodgers on Oct 4th 2019

Necessary piece of equipment when when running the kit on a plate carrier downrange. Specially when adding the expander wings. Lose and floppy gear is never good. This keeps everything nice and tight. Only complaint is the length. I’m an average size guy at 5’ 6” with a standard plate carrier. With the expander wings in use, I only have about an inch of webbing left on each end. An extra few inches or sewn over ends to prevent the webbing from slipping out would add some peace of mind.

Very adjustable
Written by Adam on Sep 10th 2019

You can adjust the strap on both ends very smart great product.

Micro back strap
Written by Gage on Aug 2nd 2019

It's really simple. This system gets rid of the molle webbing I'm so used to. I was unsure about the micro fight chest rig because I play paintball, and was worried the paintball ar mags I have are larger than real ar mags but they fit like a dream. Everything fits perfect from the skinny shoulder straps to the micro back strap. Awesome rig!

Written by Aaron on Jun 23rd 2019

Low cost piece but necessary. Keeps the rig close to your chest and tighter than the fat straps alone. Dont skimp on this piece!

Worth the minor cost
Written by Ben F on May 7th 2019

Very secure strap despite looking very simple. This strap sits just under my plates and is comfortable on the back. I have had no issues with adjustment loosening or retention failing even during demanding training / field work.

Written by Kyle on Apr 14th 2019

I've studied the Spiritus Systems rig for a while. I finally pulled the trigger and got one. The modularity is a huge selling point as well as numerous other options. I've ran this in one training class to date and I'm only mad about how long I waited to buy one.

A must have.
Written by Julian on Apr 1st 2019

It’s a stap, it goes over your back, what more could you ask for? It’s easy to adjust and keeps my chest rig secured quite well for better ease of use and is a must have to complete the micro fight chest rig.

Perfext addition to the bank robber and microfight

Back Strap - Feels required
Written by Evan on Jul 2nd 2018

I’m surprised when companies don’t include a backstrap with their chest rigs, and Spiritus had done a good job with theirs. Very simple, easy to adjust, even while wearing the chest rig, and does what it’s meant to do. I tighten mine quite a bit so that when I draw magazines, the chest rig itself doesn’t ride up with the drawing hand.

One Size Fits All
Written by Brandt on Feb 17th 2018

nothing crazy; very simple and fits all sizes of "waists" and core areas. 5/5... MC colors would be cool, but not a serious issue or complaint.

It's a perfect back strap for any configuration. Never in the way and never uncomfortable. Go on. Get it.

One size really fits all
Written by Travis on Nov 28th 2016

I had to adjust this strap until it's about a foot long in order to properly keep the rig down, but that's due to my small frame. The trap itself does not shift or wiggle after you set it, and I have had no issues with it. Very satisfied.
