The Rehband RX Knee Sleeve 5mm is the most recognised piece of kit in CrossFit, and for good reason. A 5mm neoprene sleeve that sits in the sweet spot between support, mobility and comfort. Warm enough for heavy squats. Flexible enough for rope climbs, double-unders and burpees. Durable enough to last through a year of daily training. What makes it different? Rehband has been making joint supports in Europe since 1955. The RX 5mm is the result of decades of sports-medicine R&D applied to functional fitness. 5mm SBR/Neoprene — warmth and compression without restricting movement Anatomical, pre-bent construction — sits naturally on the knee without bunching behind the joint Designed in Sweden, built for international competition standards Sold as a single sleeve — buy two for a pair Why do CrossFitters use the RX 5mm? Keeps the joint warm between heavy lifts and metcons Mild compression improves proprioception on squats and cleans Slim profile works through high-rep workouts without overheating Trusted across CrossFit Games, weightlifting platforms and UK boxes 5mm vs 7mm — which should I buy? The 5mm is the everyday all-rounder. Comfortable, mobile, and suited to mixed training. If your training is squat-heavy or you're a taller athlete who wants more support under the bar, see the Rehband RX Knee Sleeve Power Max 7mm.
