Tried X-straps and H-straps today, and I swear H is much more comfortable and flexible.
Significant part of prototype is silly stolen from Zulu Nylon Gear product – M4 Reduced Signature Chest Rig.
Please notice that prototype has some redundant connectors – because some parts were ready from previously made pieces and now were combined into new.
Thanks to that, central part of H-harness could be crearly visible, look at “butterfly” on the next photo.
Note that smallest detail with male fastex and loop, it can be with triple DTMF, but was made with sewn-in loop due to measuring mistake.
