For women who train hard and want more from every session, without adding time to the week. In a clinical study, wearing a weighted vest during HIIT increased calorie burn by 69%. Built to a woman's frame at 5 lbs, it sits flush against the body and stays put through lifts, intervals, and bodyweight work. No riding up, no chest pressure, no chafe. Build lean strength and endurance from the workout you already do. Add yours and feel it on your next session.

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.

I like the best but the sizing was really difficult to figure out and I regret the size I ordered. Was between an XL and M based on measurements & chart but wish I would’ve tried the S for a more compressive fit.

I love it but i am going to call and see about possibly ordering a larger size
I love it but i am going to call and see about possibly ordering a larger size. I am not sure of the fit, and I feel it digs under the front of my armpits a bit and wondering if it will loosen or I should go up a size. What number should I call?
Hi Jonalyn! Thank you so much for the feedback. It was great speaking with you earlier.
As we discussed, our vests are designed to have a tight and snug fit, as the compression is an important part of how the vest functions. The material will also stretch and adjust a bit over time with wear.
We truly appreciate you sharing your experience, and please feel free to reach back out if you have any other questions or need further assistance.
