Quick Answer
For the TRX Compression Racerback Tank, choose your usual size if you want a snug, supportive fit; size up if you prefer more breathing room or are between sizes. Use the size chart and your bust and waist measurements to confirm.
Why a Compression Fit Matters
Compression wear is designed to hug your body firmly, providing support and reducing muscle vibration during high-intensity workouts. The TRX Compression Racerback Tank uses a 210 GSM compression material that feels snug but not restrictive. This means the fit is intentionally tighter than a regular t-shirt or loose tank, so don't be alarmed if it feels more form-fitting than you're used to.
The racerback design allows for a full range of motion in your shoulders and arms, making it ideal for suspension training, weightlifting, or any activity that requires overhead movement. The wide range of sizes (XS and up) helps ensure you can find a fit that matches your body shape.
Sizing Up vs. Sizing Down: Trade-offs
Choosing a size up gives you a more relaxed fit, which can be more comfortable for all-day wear or if you prefer less compression. However, you may lose some of the support and moisture-wicking benefits that a tighter fit provides. A looser tank might also ride up during exercises like inverted rows or planks.
Sizing down is not recommended unless you want maximum compression for a specific purpose, like a base layer. Going too small can restrict movement and cause discomfort, especially during deep stretches or breathing-heavy workouts. Stick with your usual size for the best balance of support and comfort.
Fabric and Care Considerations
The tank is made of 76% nylon and 24% spandex, which gives it excellent stretch and recovery. The heat transfer care label eliminates tag irritation, so you won't feel any scratchy tags during your workout. To maintain the fabric's elasticity and shape, wash it in cold water and hang it to dry—avoid high heat in the dryer, which can break down spandex over time.
How to Choose Your Size
- If you prefer a snug, supportive fit: Order your usual size. The compression fabric is designed to fit closely, so your regular size will give you the intended support without being too tight. Check the size chart and measure your bust and waist to confirm your usual size is accurate.
- If you're between sizes or prefer a looser feel: Size up. This gives you a more relaxed fit that's easier to move in and can be more comfortable for all-day wear or if you prefer less compression. Remember that a looser fit may reduce the support and could ride up during inverted movements.
- If you want maximum compression for a base layer: Consider sizing down, but only if you're comfortable with a very tight fit. This is best for layering under other tops or if you want extra support during heavy lifting. Test the fit with a full range of motion before committing to a smaller size.
