Fixed-loop precision

What changes by model

PRISMA / HELIOS

PRISMA and HELIOS use fixed leg loops in the reviewed charts, so thigh range is a hard shortlist boundary rather than an adjustment to solve later.

The charts contain overlaps, but a compatible waist does not compensate for a thigh measurement outside the stated band.

Try the exact model and size with intended clothing. Fixed loops make a weighted comfort check especially important.
