I had previously owned an inexpensive weighted vest from Amazon that wasn’t really comfortable… I splurged on the aion and the difference is night and day. It’s snug and the weight is evenly distributed. It moves with me and is comfortable to wear. I would recommend this to a friend. I’m 5’3” 130 lbs and the small is perfect.

I wore it for the first time today. I walked on an incline on a treadmill and then at the end of my Zone 2 training I did split intervals sprints. The vest is comfortable, conforming but not restrictive and didn’t bother me when I sprinted. Glad I bought it and I am looking forward to incorporating it into all kinds of workouts.

A True Game Changer—From an Activewear Brand Owner
As the owner of an activewear brand, I’m very particular about what I wear and use in my workouts. I train regularly, and quality, functionality, and performance are non-negotiables for me.
Honestly, I’m blown away by this vest.
I’ve always used ankle and wrist weights, along with a neoprene compression wrap during workouts, but this completely replaces all of that. No more uncomfortable weights or dealing with Velcro constantly coming undone or shifting mid-workout.
This vest is a true game changer.
The most impressive part is that you can actually feel the difference. From the moment I put it on, I noticed a shift in my body temperature, my heart rate, and the intensity of my workout. It creates a level of resistance and heat that I’ve never experienced before in such a seamless, wearable way.
On top of that, it’s well-designed. It’s aesthetically clean, fits like a glove, stays in place no matter the movement, and is even comfortable during floor work, something I didn’t expect but really appreciate.
Beyond the product itself, the mission behind the brand is what truly sets it apart. The intentionality in how this was created is evident the moment you put it on.
I could go on and on, but this is easily one of the most innovative and effective pieces I’ve added to my routine.
A true standout and something I’ll be continuing to use consistently.

As a 52-year-old business executive
As a 52-year-old business executive, my schedule is a relentless cycle of back-to-back board meetings, international travel, and high-stakes decision-making. Over the last few years, I’ve noticed the physical "tax" of this lifestyle: a bit less energy by 3:00 PM, nagging lower back tension from long flights, and the general feeling that my recovery isn't what it used to be.
I’m naturally skeptical of "biohacking" trends, but after seeing the tech behind the Aion Vest, I decided to integrate it into my morning routine. I’ve only been using it for a short period, and frankly, the results have been immediate and undeniable.
If you’re a high-performer who feels like you’ve lost half a step, or if the "corporate grind" is starting to show in your posture and fatigue levels, do yourself a favor. This is the competitive advantage you didn't know you were missing.

Love this vest! I am a pilates instructor and wear it all day as I teach. Love the fit. Zips up with ease, although, I often wear it open :) The thing I love the most is that it looks like a trendy vest not a weighted vest!
