3mm vs 5mm vs 7mm — Pick the Right Thickness First
3mm — lightweight, breathable, full range of motion. Best for running, cycling, basketball, and sports requiring agility. Not meaningful for heavy lifting.
5mm — the versatile middle ground. Enough compression for weightlifting up to moderate loads, flexible enough for CrossFit, Olympic lifting, and functional fitness. Rehband 5mm is the benchmark.
7mm — maximum neoprene compression. The powerlifting standard. Creates a measurable spring effect out of the bottom of a squat. Restrictive for fast movement — correct for heavy squats and strongman.
