Best Knee Sleeves for Squats (2026): 5mm vs 7mm Ranked

Quick answers

What are the best knee sleeves for squats?

SBD 7mm Knee Sleeves: IPF approved, 30 cm long, 11 sizes. Rehband RX 7mm is the other heavy squat favourite, Rehband RX 5mm is the all rounder, Sling Shot 2.0 is the easier to wear 7mm, and Stoic and Gymreapers are the value 7mm picks.

Should I get 5mm or 7mm knee sleeves?

7mm for heavy squats and powerlifting, because the thicker neoprene is warmer and stiffer. 5mm for CrossFit style training, running and jumping, where you need more range. Rehband itself recommends 5mm as the all rounder and 7mm for heavy squats.

Knee sleeves are tubes of neoprene that keep your knees warm and add compression while you squat. They are not braces and they do not fix an injury, but most lifters find heavy squats feel more stable and a little more comfortable in them, especially in a cold winter garage where joints take longer to warm up.

We compared six popular sleeves from SBD, Rehband, Mark Bell Sling Shot, Stoic and Gymreapers. Thickness, length, approvals and sizing below come from each maker’s own page, read in November 2026. Sleeves pair naturally with a belt for heavy squat days; see our weight lifting belt guide if you are building out your kit.

Knee sleeves compared

Here is what each maker lists. Federation approval only matters if you compete; for training, fit and thickness matter more. “Not stated” means the figure was not on the page we read.

Which one should you buy?

• You squat heavy or plan to compete: SBD 7mm. Approved, long and firm.
• You want a heavy sleeve from a long standing brand: Rehband RX 7mm.
• You do CrossFit style workouts, running or jumping: Rehband RX 5mm.
• You hate wrestling sleeves on: Sling Shot 2.0, shorter at 27 cm with moderate compression.
• You want 7mm on a budget: Stoic or Gymreapers.

The 6 best knee sleeves for squats, ranked

1. SBD 7mm Knee Sleeves: best for heavy squats

SBD’s sleeves are the benchmark in powerlifting. SBD lists high grade 7mm neoprene at the maximum 30 cm length the rules allow, 11 sizes from 3XS to 5XL, and approval from the IPF, USAPL and USPA.

The length and thickness give a lot of warmth and a firm, supportive feel at the bottom of a squat. That firmness is also the downside: they are tight to put on and take off, and many lifters roll them on rather than pull them up. If you sit between sizes, read SBD’s own chart carefully rather than guessing.

For a home lifter whose main goal is a bigger squat, these are the ones to beat.

2. Rehband RX Knee Sleeve 7mm: best heavy sleeve runner up

Rehband has made neoprene supports for decades, and its RX 7mm sleeve is the heavy option in the RX range. Rehband describes it as maximum compression, warmth and strong support for heavy squats, powerlifting and strongman.

It is a common choice for strongman athletes and lifters who want a heavy sleeve from an established support brand. Rehband’s own sleeve guide is clear about who it is for: 7mm for heavy squats and deadlifts, 5mm for functional fitness.

Check how Rehband sells the size you want, single or pair, before ordering.

3. Rehband RX Knee Sleeve 5mm: best all rounder

Rehband calls the RX 5mm its most popular knee sleeve: 5mm neoprene for warmth, compression and full mobility, with medium support for squats, CrossFit and HIIT.

If your training mixes squats with box jumps, rowing, running or lunges, 5mm is easier to live with for a whole session. It is lighter, cooler and quicker to pull on. You give up some of the springy support of 7mm at the bottom of a heavy squat.

For most people who do not specialise in powerlifting, this is the sensible sleeve.

4. Mark Bell Sling Shot Knee Sleeves 2.0: easiest 7mm to wear

Mark Bell’s Sling Shot 2.0 sleeves are 7mm thick but only 27 cm long, with a moderate compression level, and they are sold as a pair. Sling Shot lists IPF, USAPL and USPA approval and a soft inner layer meant to stop sliding.

The shorter length and moderate compression make them easier to get on and comfortable for longer sessions, while still giving 7mm warmth. If you want maximum stiffness, Sling Shot also makes STrong sleeves at 29 cm for heavy training and meets.

A good middle ground if full length competition sleeves feel like too much.

5. Stoic 7mm Knee Sleeves: best value full length

Stoic’s sleeves match the competition template on paper: 7mm neoprene at 30 cm long, built for squats, deadlifts and heavy strength work. Stoic markets them on support, warmth and rebound out of the hole.

They usually cost less than SBD, which makes them a popular first heavy sleeve. If you plan to compete in a federation with an approved list, confirm they are on it before meet day.

For training in a home gym, they cover what most lifters need.

6. Gymreapers 7mm Knee Sleeves: best budget pair

Gymreapers sells 7mm neoprene sleeves with reinforced stitching, sold in pairs, and says its sleeves are IPF and USPA approved. They also come in kits with wrist wraps and other accessories.

They are the value end of 7mm. Expect a slightly less refined fit and finish than SBD, but the same basic job: warmth and compression on squat day.

If you are not sure sleeves are for you, this is a low risk way to find out.

5mm vs 7mm knee sleeves

• 7mm: warmer and stiffer, more support out of the bottom of a squat, harder to put on, can feel restrictive for running and jumping. Best for powerlifting and heavy squat days.
• 5mm: more mobility and comfort for mixed sessions, a bit less support. Best for CrossFit style training and general fitness.
• 3mm: mostly warmth and light compression, for running and light work.

How to size knee sleeves

Every brand sizes differently, usually by the circumference of your leg around the knee or just above it with the leg straight. Measure with a soft tape and use the maker’s own chart. Tight is normal for 7mm sleeves; if you cannot get them on at all, or they leave deep marks and tingling, they are too small. Rolling the sleeve on from the ankle, or turning it inside out and flipping it up, makes tight sleeves easier.

Buying checklist for knee sleeves

• Thickness: 7mm for heavy squats, 5mm for mixed training.
• Length: 30 cm is the competition maximum; shorter sleeves are easier to wear.
• Sizing: Measure per the maker’s chart; sizes are not consistent across brands.
• Pair or single: Check before you order so you do not end up with one sleeve.
• Approval: Only matters if you compete; check your federation’s list.
• Care: Air dry after training; heat breaks down neoprene faster.

How we ranked these knee sleeves

We compared and ranked sleeves using each maker’s published thickness, length, approvals and sizing, plus each maker’s guidance on intended use. We did not use these sleeves ourselves. We weighted support for squats first, then ease of use, sizing range and value.

Specs were read in November 2026. Federation approval lists change each year, so check yours before a meet. See how we rank gear.

Frequently asked questions

Do knee sleeves help squats?

Most lifters find they keep the knee warm and add a little support and rebound at the bottom. They are not a cure for knee pain. Not medical advice.

Should knee sleeves be tight?

Yes, 7mm sleeves should feel snug. They should not cause numbness, tingling or deep marks; that means they are too small.

Are 7mm knee sleeves good for beginners?

They are fine for squatting, but 5mm is easier for mixed training. Many beginners start with 5mm.

Can you wear knee sleeves for deadlifts?

You can, though many lifters skip them because thick sleeves can catch on the bar path. Thinner sleeves are less in the way.

How long do neoprene knee sleeves last?

Usually a few years of regular training. Air drying and keeping them away from heat helps them last.

Are SBD knee sleeves worth it?

If you squat heavy or compete, many lifters think so: 7mm, 30 cm, 11 sizes and IPF approved. For general training, a 5mm sleeve or a budget 7mm pair is enough.

Do I need one knee sleeve or a pair?

A pair, unless you only want support on one side. Check whether the listing is single or pair before you buy.

Bottom line

For heavy squats, SBD 7mm Knee Sleeves are the standard, with Rehband RX 7mm a close alternative. If you train more broadly, Rehband RX 5mm is the comfortable all rounder. Sling Shot 2.0 is the easier 7mm to wear, and Stoic or Gymreapers are the value 7mm choices.

Whatever you choose, measure first and use the maker’s chart. Not medical advice.
