Precision Over Guesswork.
This isn’t off-the-rack sizing. It’s fit that reflects who you are — how you move, how you breathe, and how you show up.
TerraNova X™ is calibrated for visual compression, unrestricted breath, and full-range motion. Get your fit right once. It stays your fit.
Measure What Matters.
You only need two numbers. No guessing. No overthinking.
-
Chest (Fullest Part)
Wrap a soft tape around the fullest part of your chest. Keep it flat, level, and comfortably snug — not tight.
-
Underbust
Measure right below your chest — around the ribcage where the band will sit.
Tip: Take your measurements standing tall, relaxed, and brea thing naturally.
Find Your Fit.
TerraNova X™ sizing is designed from the chest out — built for visual compression, mobility, and daily wear.
Use your measurements to find your exact size — no guessing, no trial and error. Just fit that feels right from day one.

What You Need to Know.
What if I’m between sizes?
Go up — you’ll still get the flat look, with more comfort. The 4-level underband lets you fine-tune the fit until it feels just right for your body.
Will my size change depending on my activity?
No. TerraNova X™ sizing is calibrated to support everything you do — training, recovery, or everyday movement.
What should it feel like when it fits right?
Flat in the mirror. Free in your breath. Secure everywhere else.
What if I’m sensitive to tightness or sensation shifts?
TerraNova X™ was designed to feel invisible in motion— no shifting, digging, or high-friction seams. If you’re sensitive to texture, stick with your measured size — it’s built to hold without overwhelming.
