What do you use for the inner belt?

Basically, I'm experimenting with using an EMDOM CM belt as my primary belt for shooting at the range rather than a larger padded belt because it's easier to change up my holsters/mag carriers etc. for using multiple setups at the range. The belt is too big to be threaded through pant belt loops and is worn over your pants/midsection like most "battle belts" but it has inner velcro to secure it to an actual appropriately lined inner belt that would also hold up your pants. So in the spirit of trying that out, I'm looking for an inner belt with the appropriate loop to do so.

HSGI sells one that is available on Amazon. Anything else I should look into?

I use these belts. They come with an inner belt. The key is to get the inner belt tight because the outer belt will only be as tight as the in er one.
