To honor exercise as a way of life we wanted to highlight our Women's Workout Black / White Split Vest in its own section called lifestyle. 

This is where fashion meets function with a striking half-white/half-black color-way. And just like our all black women's workout vest, this color style offers you the same benefit.  Get more from your existing workout without adding extra reps, sets, or time. Tailored to fit the female form, it incorporates Dynamic Resistance™ technology — Aion’s precision combination of Compression, Fractional Weight, and Neoprene Insulation — the Vest elevates caloric burn, heart rate, and active recovery, perfectly balancing range of motion while building lean muscle and endurance.


Weighing between 4.78 and 5 lbs depending on size, the Vest is made from Neoprene/Nylon Airprene and Antimicrobial materials; with a soft Neoprene lining to ensure a custom, comfortable fit that provides a full range of motion and stays in place throughout your active exercise. Heat capture in key body areas works in tandem with the Vest’s optimal weight distribution to build strength and endurance across both the muscular and cardiovascular systems and support active recovery. 

Fit
  • We suggest a Vest size the same as your favorite well-fitting t-shirt.
  • Model is 5’5” and wearing S.
  • Fits snuggly by design to take advantage of compression benefits.

Health Benefits

Builds total body strength, with an emphasis on your core strength to:

  • Build lean muscle mass
  • Improve athletic performance
  • Prevent muscle loss
  • Promote functional fitness
  • Increase strength and resilience of tendons, joints, and connective tissues
  • Vary planes of strain for comprehensive strength development

Cardiovascular Endurance 

  • Increases heart rate to mimic benefits of cardiovascular stress from traditional aerobic exercise

Increases Caloric Burn 

  • Adding extra resistance and compression to your body during exercise elevates the intensity of your workout. This heightened intensity demands more energy expenditure, resulting in a greater caloric burn.

Sport & Speed Training

  • Supports entire range of movement: torque, power, speed, and velocity
  • Develop more explosiveness and strength
  • Develop fast-twitch muscle fibers for athletic performance

Active Recovery  

  • Facilitates improved circulation and heat for recovery
  • Acts as an anxiety blanket for relaxation after training

Form Correction  

  • Improves posture through sensory cues
  • Enhances mental awareness and center of balance
  • Increases mind-body connection, creating the perception that the weight is part of you, promoting extra effort without feeling the additional stress.

Muscular Endurance 

  • Muscles adapt to this increased resistance/workload to improve endurance

CARE INSTRUCTIONS

Routine Maintenance Instructions:

How to Spot Treat-
1. Use an all-purpose wipe (we prefer Biom wipes: getbiom.co) on the affected area and gently rub across the neoprene until it makes suds.
2. Dab the area with a microfiber towel to extract any dirt or chemicals left behind.

NOTE: Spot treatment is for immediate and light cleaning purposes.

How to Disinfect-
While the neoprene is antimicrobial, if you do experience an odor, we recommend an antibacterial spray (we prefer Biokleen Bac-out Fabric Refresher).

Deep Cleaning Instructions:

1. Rinse the vest under cold water for several minutes to remove any dirt on the surface.
2. Apply a small amount of baby shampoo and rub it into the neoprene until it’s soapy.
3. Using a container of cold water, gently pour it onto the vest while squeezing the area to remove any build-up or other contaminants from the surface.
4. Use cold water to thoroughly rinse out the neoprene.
5. Repeat this process until the water comes out clear and free of soap and dirt.
6. Squeeze any remaining water out from the neoprene. Lay flat with the vest opened in a well-ventilated area (preferably outside). Allow for 24 hours of drying time.

What materials are used in the Workout Split Vest?

The Split Vest is made from high-grade neoprene fabric and stainless steel weights. Neoprene is extremely durable and helps create the compression fit of the vest, while the steel weights are designed to be perfectly centered on your chest and back to improve posture and provide a balanced weight load so you can perform at your best.

That includes:

  • Enhanced physical well-being
  • Optimized athletic performance
  • Improved muscle development
  • Higher caloric expenditure
  • Increased bone density
  • Improvements in posture, stability and mind-body connection

By combining the proven science behind resistance clothing with a compression fit and our proprietary Dynamic Resistance™ technology, we’ve created vests that are above and beyond anything that’s been offered before.
