There is also a variety of attachment methods including the Alice Clip, the Natick snap, and soft, interwoven straps.
The straps are interwoven between the webbing on each of two pieces and finally snapped into place, making for a very secure fit which can be detached with moderate effort.
The spacing is the same standard so new lasercut ladders are 100% backwards compatible with older pouches made for webbing strap construction rigs.
The benefits often quoted for laser cut single piece style is significant weight saving especially on plate carriers/rigs and items with large amount of ladder area as well as less bulk.
Another consideration is fabrics can be made in new popular patterns without need to source webbing in compatible shades including viewing conditions under night vision devices.
