Engineered to give you more from your current exercise regime, the Men’s Workout Vest comfortably intensifies strength and endurance through Dynamic Resistance™: Aion’s precise combo of Compression, Fractional Weight, and Neoprene Insulation that increases heart rate and full-body muscle strain with more caloric burn.
Available in sizes carrying 7 to 12.52 lbs (Approx. S=7, M=8, L=9, XL=10.2, XXL= 11.4, and XXXL=12.52), it promises a snug fit that keeps your Vest in place while maintaining your full range of motion during vigorous exercise — elevating your workout without adding extra time, reps, or sets.
Crafted from durable Neoprene/Nylon Airprene and Antimicrobial materials, the Vest features strategic compression and heat capture in key areas of the body to promote active recovery, maintain stamina, and achieve maximum results.
For best use when running or hiking, we advise wearing a shirt under the vest to collect perspiration and provide the best comfort.
Sizing Guide
Men’s Workout Vests
Become one with the vest: 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. If you're between sizes, opt for the smaller size for a high-compression fit. Vests are available in sizes S, M, L, XL, XXL, and XXXL.
How to Measure- Chest: Measure around the fullest part of your chest, just under the armpit, keeping the tape horizontal.
- Stomach: Measure 2 inches above the navel around the stomach, ensuring the tape stays horizontal.
