Hey ruckers! These plates are BEASTS - made in the USA to military-grade specs. The 20LB plate (9" x 11.5" x 0.92") is perfect if you're new to rucking or under 150lbs. Already comfortable with 20lbs? Step up to the 30LB size (same footprint, just thicker at 1.38"). They fit like a glove in GORUCK packs (Rucker, GR1, etc.) with zero shifting. The cast iron construction can handle 90,000+ lbs (seriously, they tested it!). Matte black finish won't rust, and those rounded edges protect your gear. Pro tip: The 45LB plate only fits the 20L/25L Rucker perfectly. Comes with GORUCK's insane SCARS lifetime warranty - if you somehow break it (good luck!), they'll replace it. These aren't just weights - they're battle-tested at over 10,000 GORUCK events. Your ruck just got way more legit!
