In a clinical study, training with a weighted vest increased HIIT calorie burn by 69%, and the Elite road takes that further. No bounce, no bulk, no plate-carrier chafe.
No matter what move you're performing, you'll feel an innate sense of resistance that builds strength and agility across every plane of movement.
Heat Detox
While the weight challenges your muscle fibers, Aion's fabrics capture heat to create a healthy sweat that detoxifies your system as you train.
Compression Fit
Our vests engage muscles to improve activation, balance, and posture — while promoting active recovery through improved blood flow and circulation.
The Research
Performance You Can Measure
Aion's clinical study tracked WHOOP, 3D motion capture, and force plate data across vested and un-vested workouts. Same athletes. Same protocols. Better outputs.
+69%
More HIIT
Higher heart rate output during the same 40-minute high-intensity protocol — measured against the un-vested control.
+18%
More Calories on a Walk
Caloric expenditure increase on Zone 2 walks of the same distance and pace. The walk gets smarter. The walk stays the same length.
56%
Time in Zone 2
Share of total walk time spent in Zone 2 with the vest on — versus 31% without. The cardiovascular work doubles.

The Stack
You Measure Everything. This Changes The Inputs.
Wearables tell you what your body did. Aion changes what your body does. It's the difference between tracking the workout and upgrading the workout.
How is this different from a regular weighted vest?
+
Most weighted vests are sized for max-load training — they bounce, strain the neck, and you take them off after the warm-up. Aion is engineered at 3–5% of body weight, with even disc distribution and a compressive shell, so it disappears on you. You wear it for the whole session. That's where the cardio and caloric numbers come from.
Will it interfere with my Oura, WHOOP, or HR data?
+
No. The vest works with the wearables you already use — and the data is what proves it's working. Expect higher average HR, more time in Z2, and elevated strain scores on the same training block.
When should I wear the Workout Vest vs. the Recovery Vest?
+
Workout Vest: any active training session — strength, HIIT, walks, hiking, plyometrics, recovery cardio. Recovery Vest: daily life when you're not actively exercising. Most of our customers eventually own both.
Is it HSA / FSA eligible?
+
Yes. The Men's Workout Vest qualifies for HSA, FSA, and GovX ID purchases. Apply your benefits at checkout.
What's your return policy?
+
30-day returns on unworn product. If the numbers on your wearables don't move, the vest doesn't stay.
