This model has 4 reviewed size combinations with adjustable leg loops. Match both body measurements to one row; the model name and generation matter more than a familiar letter size.
The reviewed WeBee rules have adjustable leg loops; the reviewed Neon rules use fixed loops. Both models still publish numeric waist and thigh boundaries. Adjustment changes how the loop closes, not whether the published range applies. Keep both measurements inside one rule before shortlisting it.
Use the exact source model shown here. A similarly named successor, a different regional listing or another manufacturer's size with the same label is not automatically covered. These are published dimensional ranges, not measurements of a harness under load.
Keep every row containing both measurements as a candidate. A value exactly on a published endpoint remains inside the inclusive range. Distance from the endpoint is a chart fact, not a comfort rating. Do not automatically choose the middle of a range or size down to eliminate an overlap.
If only your waist or thigh fits
Recheck both measurements in the intended clothing. A waist match cannot compensate for a thigh outside the model's stated range. Compare a different model or consult a qualified shop; the calculator does not bridge a gap or extrapolate a missing size.
Confirm the physical fit
Use these charts for fit comparison only. Confirm the exact current model and market listing before purchase, then test it in person. Check the exact manufacturer's buckle instructions, waist-belt retention above the hips, rise and movement. Complete a controlled weighted hang test in a shop or gym before relying on the shortlist.
