What changes by model
CORAX / LUNA
CORAX covers two broad, overlapping size bands. LUNA divides the chart into four closer waist bands while retaining adjustable leg loops.
CORAX uses numbered sizes 1 and 2; LUNA uses XS through L. These labels do not convert between models. Check both waist and thigh against the row for the exact model: CORAX can leave two sizes compatible, while LUNA can expose a waist–thigh mismatch.
