Rehband Rx Knee Sleeve 5mm

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.

Pair it with

• Rehband RX Elbow Sleeve 5mm — the matching elbow support
• Rehband X-RX Wrist Wrap — for heavy overhead and snatch work
• Rehband X-RX Lifting Belt — for max-effort squats and deadlifts

Included in your order

• 1 × Rehband RX Knee Sleeve 5mm (Also sold as a pair)

Who uses Rehband?

• CrossFitters at every level, from novice to Games-level
• Weightlifters and powerlifters
• Hyrox athletes
• Physios and their clients rehabbing patellofemoral pain, tendinopathy and general wear

What size should I buy?

Measure the circumference of your leg 15cm above the kneecap, then match to the Rehband size chart shown on the product images. A tighter fit gives more support; most athletes do not size up.
