A full-length legging in a 260 g/m² double-knit — the heaviest knit we use on a legging. This is the piece the squat test method was written around. It passed at a 90° squat against a same-colour base layer at every size in the run, including the lightest colourway.
These three are on the sewn-in label as well as this page. Care symbols and fibre notes.

5.0
I have bought four pairs of leggings that claimed the same thing and returned three. These are heavy enough that I stopped thinking about it by the second set. The fabric weight being printed on the page is what made me try them.
4.0
These are noticeably thicker than what I usually wear and that is a trade-off in a hot gym. Worth it for the sessions where I am under a bar. I would not run in them.

Boxy tee cut wide at the armhole so a bar path is not blocked.
