Overview
The MiR Super Slim Air Flow Vest is an ultra-low-profile weighted training vest designed for maximum mobility and breathability. Measuring just 14” x 15” x 1”, it is MiR’s most compact design, engineered to fit snugly against the body to prevent bouncing and shifting during high-intensity workouts. Its streamlined form allows it to be worn discreetly under a sweatshirt or jacket, while the specialized cotton-blend airflow material ensures the athlete stays cool even during endurance training or rucking.

Performance Benefits
Zero-Bounce Stability: The high-ride design and mid-chest belt ensure the vest stays tight to the torso, eliminating the distracting bouncing often found in bulkier vests.
Maximum Mobility: Narrow shoulders and the super-slim profile allow for a full range of motion in the arms, making it suitable for pull-ups, push-ups, and running.
Discreet Training: Because it is only 1" thick, the vest can be worn under regular clothing, allowing for weighted walks or commutes without drawing attention.
Breathability: The airflow material facilitates heat dissipation, reducing the "swampy" feeling common in nylon or tactical-style vests.
Scalable Intensity: The ability to add or remove individual 0.9 LB weights allows for precise progressive overload tailored to specific training goals.
Maintenance and Care
Washing: The vest itself is machine washable. Important: Remove all iron weights before washing. Use cold water and a gentle cycle.
Drying: Air dry only. Do not place the vest in a machine dryer, as high heat can damage the cotton-blend fabric and the heavy-duty zipper.
Weight Care: Keep the iron weights dry to prevent surface oxidation. If they become damp from sweat, wipe them down and allow them to air dry before re-inserting them into the vest pockets.
Sanitation: For frequent use, it is recommended to wear a moisture-wicking shirt under the vest to reduce the frequency of full washes.
Frequently Asked Questions
Q: Can I add more weight to the 8 LB vest later? A: Yes. The vest is fully expandable and features numerous weight pockets. It is generally more cost-effective to buy the heavier package upfront, but additional iron weights can be purchased separately to increase the load.
Q: Will this vest fit someone with a small frame? A: Yes. The "one-size-fits-most" design utilizes three adjustable straps and a mid-chest belt to tighten the vest significantly for smaller athletes while remaining expandable for larger frames.
Q: Can I use this for CrossFit-style pull-ups? A: Yes, though some users note that due to the close fit, the edges may rub during certain high-volume gymnastics movements. Proper adjustment of the chest straps can help minimize this.
Q: Is the zipper durable enough for heavy weights? A: The MiR zipper is a specialized heavy-duty component rated to withstand up to 200 LBS of pressure, well above the maximum weight capacity of the vest.
