hmmm.... then skin serve me better...There is a difference between the current modulus and skin. The current modulus have paddings to protect the equipments from reasonable hit and knock during movement, whereas the Skin ones does not have paddings.
Because of the paddings, the modulus are bulky similar to the lowpero belts accessories, which sometimes will occupy space unnessary space issues in the bag you carry. I normally will just put my lens in the moudulus and keep in the camera bags, of course it will occupied more space in the camera bags.
As for Skin, because no padding. It is easier to keep in the bags. Basically, fold and keep. During events just unfold and dump my equipments in. Moreover, you can put others things in beside the lens and cameras. I intended to use skin strobe to hold my big walkie-talkie, which I am currently using lightning fast. Skin Chimp cage pop down for my batteries, blower or even portable harddisk or pocket viewer and other stuffs. This Skins reminds me a similar product from Saffrotto which looks like a SBO.
Both modulus have their pros and cons. It depends on the user's preference and how he/she would like to utilize and organise their equipments. But do remember, for belt system, you need to seek the balance around the belt, or else your waist will suffer injury.
