Framing, fixing, finishing — zip the pockets on for the tools you need close, zip them off the second your hands are free.

In and out of roof space and switchboards all day — less bulk at the hip means fewer snags and more room to move.

On your feet across the whole site all shift — shed the dead weight of a full belt when you're walking the job, not swinging a hammer.

Crawling under floors and into tight cavities — zip the pockets off to slide through gaps a full belt would never fit.
