Here’s everything you need to know about the Aion Weighted Vest and why F45 Training chose this partnership.

Choosing the right Aion vest depends on how you move—and how you want to feel. If you’re training hard and chasing performance, the Workout Vest is your go-to. Designed for HIIT, running, hiking, and recovery, it delivers patented compression, heat capture, and resistance equal to 3–5% of your body weight. Expect higher caloric burn, better Zone 2 output, and serious gains in strength, posture, and endurance.
For everyday strength and subtle activation, the Recovery Vest (men’s) and Walking Vest (women’s) offer a more relaxed fit with 5.5 to 7.5 lbs of evenly distributed weight. Ideal for posture support, anxiety relief, and low-impact movement, they seamlessly integrate wellness into your daily routine—no gym required.

Most weighted vests are bulky, uncomfortable, and built only for certain workouts. Aion is built for real life.

Aion Vests useDynamic Resistance™— our signature combination ofcompression, heat capture, and weightthat makes your body work harder with every movement. Instead of sitting like a static load, the vest hugs your core and subtly shifts as you move, forcing your muscles to stabilize, warm up, and engage continuously.
Made withpremium materialsit’s engineered to elevate your performance and endurance without compromising comfort or style.

Our sizing is based on your body measurements. We recommend using our in-depth sizing guide (link) or the fit guide on the product page to measure your chest and torso and understand how the vest should fit and feel on your body.

Yes! Aion vests are designed to enhance most forms of training — from walking, mobility work, and strength circuits to functional conditioning. The Dynamic Resistance™ makes your body work harder with every movement, while the compressive fit supports your posture and core.
