***IMPORTANT: We have resized our PR Knee Sleeves so please confirm sizing based upon chart below. DO NOT SELECT BY PREVIOUS SIZE ORDERED. The PR Knee Sleeves are the stiffest, most aggressive 7mm sleeves on the market. Built with ultra-dense neoprene and a cone-shaped design, they deliver maximum compression, unmatched support, and confidence under your heaviest squats. These sleeves are trusted by elite lifters who demand the absolute most from their gear—perfect for setting PRs on the platform or pushing limits in training. If you’re not ready for an ultra-aggressive, competition-level sleeve, we recommend choosing our Performance Knee Sleeve (PKS). Sizing Guide Use a soft tape measure. Measure around your knee joint and the thickest part of both calves. Use the larger measurement to determine your size from the chart. If you measure between sizes, round up. ❌ Do not size based on sleeves you’ve owned before, or on what works for a training partner or friend. 👉 For visual guidance, please see the sizing video in the product photos.👉 Still unsure?
