It's a decent Belt of its own, to the point that I like wearing it as an everyday belt. It's obviously simple to don and doff and on top of the intended functionality, which I will address in my review of the shooter's belt, it's the proper size for the clamps of say a T-Rex Arms IWB holster to clamp on to. This is a bonus since you might be doing something (e.g. a fun rangetrip) where you start out with your pistol in an IWB holster, which at some point is then swapped out for something attached to the shooter's belt. Switching to the gear belt is rapid, since you don't need to un-buckle the underbelt to tension it after removing the IWB. A note regarding sizing. Being a tall half-hobbit with a BMI just shy over the slightly overweight line, I just barely measured both belts for size G2, however when donning the underbelt, I pretty much ran out of adjustment space. it is possible to wrangle just the tip of the adjustment section through the buckle, though once successful with losing fat mass, I'll be needing a G1 sized underbelt. So if you're like me and measure just on the border between two sizes, get the underbelt at the lower size and the shooter's belt at the larger size. All in all I love it. It could be improved by offering a leather brown version for those who like to wear it on an everyday basis without being the guy with conspicuously inconspicuous clothing. Update: It works fine as an underbelt for the shooter's belt. No surprise here, really, but still. Be smart and don it with an offset under the shooter's belt to help loosening and tightening, you're liable to want to readjust your general clothing during the day at some point, there IS a downside to directly linking your gear belt to your trousers.
