The Ten-Speed chest rig incorporates a four-partition panel of this Ten-Speed system across the center panel of the harness. On either side are three rows of MOLLE webbing that allow the user to add an endless array of pouches and accessories. If that isn't enough storage space, the entire front panel is an 18 x 6-inch pouch with a large hook-and-loop enclosure at the top. This pouch is a great place to dump your administrative gear.
I started my evaluation by loading up the Ten-Speed with four loaded M4 magazines and adjusting the straps to fit my torso. The ergonomics of the harness were very good, and the straps were wide enough to distribute the weight well. As a "bail-out" rig this set-up would work perfectly. It is almost as quick to get into as a rifle sling and carries enough ammo for the worst of "bad day" scenarios. Until that day comes, the Ten-Speed rolls up neatly and takes up very little room in a gear bag or rifle case.
Next, I decided to replace two of the M4 magazines with a TASER and my police radio. Both fit snugly in the large elastic panels and felt very secure. I added a double pistol pouch on one side and a small zippered admin pouch on the other and loaded both fully. The extra weight was noticeable but it still felt well distributed.
As soon as I finished playing "mix and match" with my gear, I reverted back to the simplest form and what the rig was designed to do in the first place, carry ammo and lots of it. With the added double pistol pouch my full load-out totaled 30 rounds of .40 caliber pistol and 120 rounds of 5.56mm rifle ammo.
I then hit the range. The first thing I noticed was how securely the rig stayed in place once I got the straps fastened properly. With the rig positioned just below my mid chest line, I was able to reach all of the magazines and, although very snug, draw them with ease. Here is where I encountered this system's weakness.
