Size Guide

Quick Navigation

Choosing the right size should feel straightforward. This guide explains how ENGINE garments are designed to fit, how to take your measurements, and where to find product-specific size information.

For the most accurate fit, always refer to the size guide on each product page.


How Our Garments Are Designed to Fit

  • ENGINE pieces are designed for training and movement

If you're between sizes or prefer a less compressive feel, sizing up is generally recommended.
