Quick Summary
Rehband builds medical-grade neoprene knee sleeves with a long history in strength sports, while Gorilla Wear leans toward thicker, budget-friendly sleeves aimed at lifters who want maximum stiffness. The choice comes down to flexible support versus stiff rebound, so pick 5mm for CrossFit and high-rep sets or 7mm for powerlifting and heavy squats.
- Rehband and Gorilla Wear approach knee sleeves from opposite directions, one medical-grade and one budget-focused.
- 5mm sleeves suit CrossFit, general strength and high-rep sets with flexible, moderate compression.
- 7mm sleeves suit powerlifting and heavy squats but limit range of motion and feel warmer.
- Size up between sizes for easier on-off, or size down only for maximum compression.
- Never use fabric softener or bleach on neoprene because both break down the material.

Rehband vs Gorilla Wear: The Core Differences
Rehband and Gorilla Wear approach knee sleeves from opposite directions. Rehband builds medical-grade neoprene support with a long history in strength sports, while Gorilla Wear leans toward thicker, budget-friendly sleeves aimed at lifters who want maximum stiffness. Below, we break down where these two sleeves diverge.
Construction and Materials
If you want a fuller picture of how different sleeve builds compare, our guide to Rehband alternatives for heavy lifting covers the trade-offs.
Support and Compression Levels
For lifters weighing how much compression actually helps, our breakdown of the benefits of compressive gym gear explains what tightness does for joint stability and blood flow. The short version: more compression is not automatically better. Too much restricts range of motion and can cut circulation during long sessions.
7mm Knee Sleeves vs 5mm: Thickness and What It Changes
Here is how the two thicknesses compare in practice:
| Thickness | Best For | Feel | Trade-off |
|---|---|---|---|
| 5mm | CrossFit, general strength, high-rep sets | Flexible, moderate compression | Less rebound out of the hole |
| 7mm | Powerlifting, heavy squats, low reps | Stiff, strong rebound | Limited range of motion, warmer |
Best Knee Sleeves for Weightlifting: Stability Under the Bar
Gorilla Wear's thicker sleeves can work for weightlifting, but the added stiffness often gets in the way of deep catches. Lifters who prioritize a stable, locked-in feel on heavy squats may prefer the thicker option. Those who need to move through a full range under the bar usually do better with a thinner, more pliable sleeve.

How to Size Knee Sleeves: A Head-to-Head Fit Guide
- Measure both knees; a small difference is normal.
- Size up if you are between sizes and want easier on-off.
- Size down only if you want maximum compression and can tolerate a tight break-in.
- Expect a new sleeve to feel tighter than it will after a few sessions.

Frequently Asked Questions
Are Rehband or Gorilla Wear knee sleeves better for CrossFit?
It depends on the session. Rehband's thinner 5mm sleeves suit metcons and high-rep work where you need range of motion and breathability. Gorilla Wear's thicker options give more support for heavy squats but can feel restrictive during burpees or box jumps. Many CrossFit athletes keep a 5mm pair for conditioning days and a 7mm pair for strength days. Try both thicknesses on a light session before committing to a full WOD.
What is the difference between Rehband and Gorilla Wear knee sleeves?
Rehband is built around neoprene compression with a focus on joint warmth and a snug anatomical fit, and it has a long history in strength sports. Gorilla Wear leans toward thicker, stiffer sleeves aimed at heavy squats, with a more bodybuilding-oriented brand identity. The practical split comes down to thickness, stiffness, and how much rebound you want out of the hole. Check the stated millimeter thickness on each model before buying.
How should knee sleeves fit?
They should feel tight when you pull them on, with no bunching behind the knee and no pinching at the top edge. You should be able to squat to depth without the sleeve sliding down or rolling. If you can spin the sleeve easily around your leg, it is too loose. If your leg goes numb or the sleeve cuts off circulation after a few minutes, size up. Measure your knee circumference mid-patella and match it to the brand's size chart.
Can knee sleeves help keep your knees warm during workouts?
Yes. Neoprene traps heat against the joint, which is why lifters wear sleeves even on lighter days. Warmth supports blood flow and can make the knee feel more prepared under load. Thicker 7mm sleeves hold heat more aggressively, while 5mm sleeves breathe better for long conditioning sessions. If you train in a hot gym or sweat heavily, a thinner sleeve keeps warmth without overheating.
