Knee Sleeves Guide: Keep Your Knees Warm and Supported for Heavy Squats

All Equipment

What Are Knee Sleeves?

Knee sleeves are tight-fitting neoprene tubes that slide over your knee joint. They compress the area, retain heat, and provide proprioceptive feedback — your brain gets a better sense of where your knee is in space, which can improve movement quality.

They’re not knee wraps (which are long elastic bandages wound tightly for maximum support and rebound). Sleeves are less restrictive and designed for everyday training use.

Who Needs Knee Sleeves?

Anyone who squats regularly will benefit from knee sleeves, particularly if you train in a cold gym, have a history of knee niggles, or squat heavy. The warmth alone makes a noticeable difference — cold joints don’t move as well and are more prone to discomfort.

If you’ve got healthy knees and train in a warm environment, sleeves are a “nice to have” rather than essential. But most serious squatters end up buying a pair eventually and wonder why they waited.

What to Look For When Buying

Thickness: 5mm sleeves are thinner, more flexible, and suited to CrossFit or high-rep training. 7mm sleeves are the standard for powerlifting and heavy squatting — they offer more support and a slight rebound effect at the bottom of a squat.

Fit: Knee sleeves should be tight. Measure the circumference of your knee at the centre of the kneecap and follow the manufacturer’s size chart carefully. If you’re between sizes, go smaller for more support or larger for comfort.

Material: Neoprene is standard. Higher-quality neoprene retains its elasticity longer and doesn’t stretch out as quickly. Cheaper sleeves tend to lose compression within 6-12 months.

Seams: Reinforced stitching matters. Cheap sleeves often fail at the seams first. Look for double or triple stitching.

Our Top Picks

1. SBD Knee Sleeves (7mm) — £65-£80

The undisputed king. Used by more competitive powerlifters than any other brand. Extremely durable neoprene, excellent compression, and IPF-approved. They’re tight to get on but last for years.

2. Rehband 7mm Knee Sleeves — £40-£55

The original knee sleeve and still one of the best. Slightly less aggressive compression than SBDs, which some lifters prefer. A proven design that’s been trusted for decades.

3. Bear KompleX Knee Sleeves — £25-£40

A great budget option that punches above its weight. Popular in CrossFit communities. Not quite as durable as SBD or Rehband but excellent value for the price.

4. Gymreapers Knee Sleeves (7mm) — £25-£35

Another strong budget contender. Good compression, decent neoprene, and available in multiple colours. A solid first pair.

Care Tips

Knee sleeves absorb sweat and will smell awful if you don’t wash them. Hand wash after every session or machine wash on a cold, gentle cycle. Turn them inside out and air dry — never tumble dry neoprene or it will break down.

Some lifters use plastic bags to help slide tight sleeves on. Put a carrier bag over your foot, pull the sleeve up over it, then remove the bag through the top.
