Mir Weighted Vest Weights Review
MIR 90LBS PRO Long Weighted Vest
ADVANTAGES
LIMITATIONS
The MIR 90LBS PRO is a beast of durability and weight capacity, engineered for serious athletes who demand maximum resistance without compromise. With solid iron 3lb plates that snap in and out in seconds, this vest lets you scale from bodyweight to 90lbs with precision. Its compact 16″ x 13″ x 2″ design defies expectations—packing massive weight without the bulk, thanks to dense iron bars instead of loose pellets. If you’ve struggled with flimsy vests that sag or overheat, this one solves both with military-grade 1200D nylon and full-bodied weight distribution that keeps load centered and stable.
In real-world testing, the vest shines during high-intensity ruck marches, strength circuits, and plyometric drills, where stability and weight retention are non-negotiable. The tight weave of the nylon shell resists abrasion from backpacks and gear, while the internal layout prevents shifting—even during burpees or sprints. It’s not the lightest option when fully loaded, but the low-profile iron bars minimize bounce, making it surprisingly agile for its class. That said, the lack of airflow becomes noticeable in humid conditions; unlike mesh-based vests, this one traps heat, so it’s best suited for outdoor or short-duration indoor sessions.
Compared to the slimmer MIR Air Flow models, the 90LBS PRO trades breathability and low-profile wear for raw capacity and ruggedness—a fair trade for military trainees or strength athletes. It’s overkill for casual walkers or light trainers, but ideal for tactical prep, advanced calisthenics, or load adaptation. While the Super Slim 32LBS model wins for discretion and comfort, this one dominates in sheer performance ceiling and bombproof construction, offering a level of long-term value that cheaper vests can’t match.
MiR Super Slim Vest 32LBS
ADVANTAGES
LIMITATIONS
The MiR Super Slim Air Flow Vest redefines comfort in weighted training with a clothing-like fit and exceptional breathability, making it perfect for endurance athletes and daily wearers. Crafted with a soft cotton-blend fabric, it feels nothing like traditional scratchy nylon vests—instead, it drapes like a second skin and stays cool even during prolonged cardio. The .9lb incremental weights (3/4″ thick) allow ultra-fine tuning from 4 to 32lbs, ideal for gradual progression without jarring jumps. If you’ve ever quit a vest due to chafing or overheating, this one eliminates both pain points with intelligent design.
During testing, the vest proved exceptionally stealthy and mobile, easily worn under jackets or sweaters for outdoor runs or urban rucking. The expandable D-rings adapt to your ribcage during deep breaths, preventing the “cage lock” feeling common in rigid vests. Whether used for jogging, hiking, or HIIT, it stays put without excessive bounce, thanks to its snug 13″x15″ footprint and triple-strap system. However, the 32lb ceiling limits serious strength trainers, and the cotton blend, while comfortable, absorbs sweat and takes longer to dry than synthetic alternatives.
Against the 60LBS Air Flow model, this vest sacrifices capacity for slimness and wearability, making it the clear pick for daily conditioning, weight loss, or mobility-focused training. It’s not built for tactical loads or extreme resistance, but for users prioritizing comfort, thermoregulation, and discretion, it outperforms bulkier rivals. While the 60LBS version offers more growth room, this one delivers a superior balance of lightness, fit, and airflow—a premium choice for those who move more and lift less.
miR Air Flow Vest 60lbs
ADVANTAGES
LIMITATIONS
The miR Air Flow Weighted Vest (60LBS) hits a sweet spot between capacity and comfort, making it the go-to for athletes who want serious weight without sacrificing breathability. With removable 3lb solid iron plates, it scales from 20 to 60lbs in easy steps—perfect for progressive overload in calisthenics, rucking, or stair climbs. Its hybrid airflow fabric wicks sweat and dissipates heat far better than standard nylon vests, so you stay cooler during long sessions. If you need a vest that handles heavy loads but won’t cook you alive, this one delivers where it counts.
In real-world use, the vest excels during moderate to high-weight scenarios, like weighted pull-ups, lunges, or 5-mile rucks, where stability and cooling matter. The zipper design allows quick on/off, and the internal layout keeps weight centered, minimizing sway. At 60lbs, it’s substantial but manageable, with a fit that accommodates most torso sizes thanks to adjustable straps. That said, the 3lb plate increments can feel too coarse for fine-tuning early in training, and while the fabric breathes better than basic models, it’s not as cooling as the Super Slim’s cotton blend.
Compared to the 90LBS PRO, this vest offers less total weight but better ventilation and lighter feel, making it more versatile for mixed training. It lacks the lifetime durability of the 90LBS model’s 1200D nylon, but still holds up well under regular use. For users who want more than 32lbs but don’t need 90lbs, this model bridges the gap with smart airflow, solid construction, and scalable resistance—a better all-rounder than either extreme.
Choosing the Right Weighted Vest: A Comprehensive Buying Guide
Weight Capacity & Your Goals
The most important factor when selecting a weighted vest is its weight capacity and how it aligns with your fitness goals. Vests range from relatively light (3lbs individual weights for accessory use) to substantial (90lbs for serious training). If you’re new to weighted vests, starting with a lower weight (around 10-20% of your bodyweight) is crucial to avoid injury and gradually increase the load as you get stronger. Higher weight capacities (60lbs+) are ideal for experienced individuals focusing on strength and endurance training, or those needing significant resistance for specific activities like running or hiking. Consider whether you plan to add weight over time; a vest with removable weights offers flexibility.
Vest Fit & Comfort
A comfortable, secure fit is paramount. A poorly fitting vest can cause chafing, restrict movement, and even lead to injury. Look for vests that offer adjustability – typically through side straps and sometimes shoulder adjustments – to ensure a snug, yet comfortable fit. The vest should distribute weight evenly across your torso, avoiding pressure points. “Slim fit” designs are beneficial if you plan to wear the vest under clothing or prefer a less bulky feel, while “full-bodied” vests distribute weight more broadly. Consider the material; some vests utilize breathable materials (like the “Air Flow” designs) to minimize overheating during intense workouts. Shoulder padding (available separately) can also significantly enhance comfort, especially during high-impact activities.
Weight Type & Durability
The type of weight used impacts the vest’s overall feel and longevity. MIR vests primarily use solid iron weights, which are incredibly durable and built to last. These weights are typically removable, allowing for easy adjustment. The quality of the vest’s construction is also critical. Look for vests made with durable materials like 1200-D Nylon, which can withstand the rigors of regular use. A heavy-duty zipper (as found in some MIR models) is another indicator of quality, ensuring the vest remains securely fastened during workouts. Consider a lifetime warranty as a sign of the manufacturer’s confidence in their product.
Washability & Maintenance
Maintaining hygiene is important, especially with a vest that will be used during sweaty workouts. Machine washable vests (like the Air Flow Vest) offer convenience, while others may require spot cleaning. Consider how easy the vest is to clean and maintain based on your lifestyle and workout frequency.
Additional Features
- Weight Increment: Smaller weight increments (e.g., 0.9lbs or 3lbs) provide more granular control over resistance.
- Pocket Design: How weights are secured in the pockets impacts stability. Secure, well-designed pockets prevent shifting during movement.
- Compatibility: If you are considering buying individual weights, ensure they are compatible with your existing vest model.
