Women’s Vests
(Full - Length/Crop)

How it Fits

  • Aim for the vest that closely matches your measurements for high compression to maximize the performance vest's proper fit, comfort, and benefits.
  • While some may believe a slightly larger fit is more comfortable during movement, the vest is designed to feel like a seamless extension of your body, providing a snug feel.
  • When pulling up on the shoulders, the vest should barely move.
  • When zipping it up, there should be a noticeable stretch in the fabric.
  • Ensure a tight fit, with the correct vest exhibiting a 4 to 8-inch gap between the left and right zipper before stretching to zip up.
  • You should have an overall high-compression fit around your frame.

Size Preferences

The size you choose may change based on how you intend to use your vest. By surrounding your core with constant compression, our vests engage your muscles to improve toning, balance, and posture, even while you’re recovering. The compression and fabrics capture heat against your skin, creating a healthy sweat that helps detoxify your system as you train.

For best fit, go with the vest size that fits your measured chest size.

Compression Comfort Level

Our vest offers high compression for optimal benefits in toning, balance, and posture. By surrounding your core with constant compression, our vests engage your muscles to improve toning, balance, and posture, even while you’re recovering. The compression and fabrics capture heat against your skin, creating a healthy sweat that helps detoxify your system as you train.

If you prefer a high-compression fit and all the benefits that come from it: Do not size up, if you are between sizes, size down. 

If you prefer a more comfort fit and are not so serious about the benefits of high compression: Stick to your intended size.

How to Measure

Stomach: Measure 2 inches above the navel around the stomach, ensuring the tape stays horizontal.

The vest is intended to move with you. It should hug your body tightly and extend above your hips. Ensure a secure fit by following these guidelines and matching your measurements with the corresponding size for the best fit on our size chart. Vests are available in sizes XS, S, M, L, and XL.
