Shopping for high-performance gear online shouldn't feel like a guessing game. We know that the right fit is the difference between a distracted workout and a new personal record. To help you move with total confidence, we have developed a streamlined process to ensure our technical fabrics contour perfectly to your unique body shape.
The Essential Body Measurements to Record
To ensure a flawless fit, we recommend measuring your bust, waist, and hips with a soft tape. For leggings, we suggest checking your inseam to ensure the length matches your preference. Keeping these numbers handy allows us to help you select pieces that offer the right support without being restrictive during high-intensity training sessions.
Consulting the Official oNMexis Size Chart
Once you have your measurements, we invite you to visit our Size Chart to find your match. We have meticulously calibrated our sizing to account for the high elasticity of our performance materials. By aligning your physical measurements with our specific categories, we ensure that the gear you order provides the intended compression.
Understanding Fabric Stretch and Compression
We choose high-quality materials that offer varying levels of compression depending on the activity they are designed for. When you look at our size chart, consider whether you prefer a "second-skin" feel or a slightly more relaxed fit for your daily routine. We provide detailed descriptions for every item so you can choose the right level of support.
Testing for Functional Movement
A perfect fit must perform under pressure, so we encourage a quick movement test once your gear arrives. We design our pieces to stay in place during deep squats and high-intensity sprints alike. If the waistband stays secure and the fabric remains opaque during a full range of motion, we have successfully found your ideal match for peak performance.
Finding the right gear is essential for your fitness journey, and we are committed to making that process seamless. By using our precision measuring tips and the official oNMexis size chart, you can shop our collection with absolute certainty.
