One of our newer members, Dan G, had a slick inner/outer belt combo that I asked about. Turns out he made it himself and can make other Cordura gear, like messenger bags, if you're interested.

The inner belts have a high density polyethylene stiffener and a mesh covered foam liner so they breath better and offer some padding for long wearing comfort. The outer belts also have a high density polyethylene stiffener. The outside is covered in 1000D cordura to make them very abrasion resistant. On the inner and outer belts the hook and loop goes all the way to the edges of the belt for maximum grip and stability.
The inner belts can either have OD hook or black hook. The outer belt can be just about any color you want. On hand I have solid colors in black, khaki, blaze orange, and OD. I also have some camo fabrics in woodland, multicam, CADPAT, ACU and MARPAT. I also have some green, tan, and black snake skin lying around. If someone wants a different color I can get a hold of just about any type of camo or solid color. I just need the exact waist measurement of where the belt will sit.
The inner belts are $30 and the outer belts are $40. Any belts over 48" add $10.
