do not stay in place

I don't really like these. They don't stay in place, and the rubbery band is useless.

Very comfy, but the little sticky thing on the edge that sticks to you leg (don't know what it's called) is peeling off, which is a bit disappointing after only a few years/washes.

Wedgie central

The material is lovely and silky to touch but the combination of the cut and the stretchy fabric causes the undies to ride up and pull in uncomfortable ways (and I hate the feeling of a g-string).
I sadly bought 3 pairs of these hoping they would fit the same way as the biotracker full briefs and they definitely don’t. These run smaller on the waist (which feels quite firm) and are really loose everywhere else. They are sadly quite uncomfortable so have been shoved into the ‘emergency’ section of the undies drawer.

Moves around all over the place :(

Advertised as stay-put but they really don’t. Put them on and immdiately they shifted and irritated me! I have the other full-briefs and love them. Don’t like this silky fabric as it feels too slippery under my active shorts and, again, they shift! Wedgie central.
