The miR Air Flow Adjustable Weighted Vest is a 20 lb adjustable vest designed for walking, rucking, and general fitness workouts. Key features include:

  • Adjustable weight system: Removable 3 lb solid iron weights allow users to start light and progress; all weights can be added or removed within seconds
  • Air flow design: Hybrid breathable material prioritizes heat dissipation and sweat management over heat retention, with softer materials replacing harder scratchy alternatives
  • Machine washable: Weights are removable, allowing the vest itself to be machine washed and tumble dried
  • Lifetime warranty: Covers damage during workouts
  • Fit & adjustability: Bottom straps adjust to keep the vest snug across different body sizes

The vest is solid iron throughout, marketed as durable enough to last a lifetime. It sits in the mid-range of the weighted-vest category ($105), offering good value for users seeking an adjustable, breathable option for walking and rucking rather than tactical or CrossFit-specific workouts. miR has established modest recognition in fitness circles, though it lacks the category dominance of brands like 5.11, RUNmax, or Hyperwear.
