Polyfit PL8 Weighted Backpack for Olympic Weight Plates

【HIGH PERFORMANCE WEIGHT PLATE BACKPACK】 Built for Olympic-style plates, this weighted backpack locks weight tight for rucking and bodyweight training. Secure fit stays put during push-ups, pull-ups, squats, and dips—and it’s great for rucking, hiking, and endurance training.

【COMPATIBLE WITH OLYMPIC PLATES (NOT INCLUDED)】Compatible with most gym plates up to 17.5" in diameter and 3" thick. Designed for 2-inch center hole Olympic-size weight plates found in home and commercial gyms—whether cast iron or bumper style. Holds one large or multiple smaller plates, with a recommended maximum load of 45 lbs (20 kg) for safe use.

【DUAL-LOCK SYSTEM | ZERO-BOUNCE CARRY】Our patent-pending design locks weight plates inside with quick-release steel buckles and outside with a compression system—keeping the load secure and bounce-free during rucks or workouts.

【STERNUM & WAIST SUPPORT | LOCKED-IN STABILITY】 Adjustable sternum and waist straps secure the load snug to your body for improved stability, balance and posture. Easily adjust for a custom fit and better weight distribution in any workout.

【DURABLE MATERIALS | BUILT TO LAST】 Built from tough 600D polyester with reinforced stitching, rugged zippers, and a water-resistant coating for easy wipe-clean care (not machine washable). Tactical-grade aluminum quick-release buckles ensure durability and fast on/off during intense training.
