Size Guide
HIVOLT uses three sizing systems across the range, because different garment categories are cut to different blocks. Every product page carries its own measurement table under Details — this page tells you which system applies and how to measure.

Reading the product tables
Measurement tables on product pages are garment measurements laid flat, not body measurements. Chest and waist figures are half-circumference — double them to compare against your own body measurement. Length is measured from the highest shoulder point to the hem.
How to measure yourself
Chest / bust: around the fullest point, tape level under the arms.
Waist: around the narrowest point of your torso.
Hip: around the fullest point, roughly 8in below the waist.
Inseam: from the crotch seam to the ankle bone.
Measure over bare skin with a soft tape, level and snug but not tight.
Between sizes?
Size down for compression pieces — leggings, sports bras, cycling shorts, fitted tees. They are cut to work under tension.
Size up for relaxed layers — hoodies, jackets, joggers, basketball shorts.
