Quick answer: To measure for Nordic Lifting 7mm knee sleeves, wrap a soft tape measure around your thigh 4 inches (about 10 cm) above the top of your kneecap and match that number to the size chart in the product photos. Follow the chart for a comfortable fit on long sessions, or go one size down for a tighter, competition-style fit that is harder to pull on. Other brands may measure at a different spot, so always use the chart for the sleeve you are buying.
- Knee sleeves are pull-on neoprene or knit sleeves that give the knee warmth and a snug, compressive fit. They have no hinges or straps, unlike a knee brace.
- Thickness sets the feel: 7mm neoprene is the thickest and firmest, built for heavy squats; thin knit compression sleeves are built for movement and long wear.
- A good fit is snug, stays in place and still lets you bend the knee fully.
This guide brings our knee sleeve articles together in one place: what knee sleeves are, how they work, why lifters wear them, which thickness to choose, how to measure for the right size and how they should fit.

What are knee sleeves?
Knee sleeves are tube-shaped sleeves you pull on over the knee. Lifting sleeves are usually made of thick neoprene, while lighter compression sleeves are knitted from nylon with spandex and latex yarn for stretch. They wrap the knee in a close, warm, compressive fit without locking the joint, so you can still squat, lunge and move freely.
Knee sleeves vs knee pads vs knee braces
| Gear | What it is | Main purpose | Mobility |
|---|---|---|---|
| Knee sleeve | Pull-on neoprene or knit sleeve, no rigid parts | Warmth and a snug, compressive fit while you train | High |
| Knee pad | Padded cover over the front of the knee | Cushioning when kneeling or on hard contact | High |
| Knee brace | Brace with hinges, straps or stays | Limits how the joint moves; chosen with a health professional | Limited |

How do knee sleeves work?
Knee sleeves work through compression and warmth. The sleeve hugs the knee evenly, and thick neoprene holds in heat, so the area stays warm from your warm-up sets through your working sets. A thicker, tighter sleeve feels stiffer around the knee; a thinner sleeve feels lighter and moves more easily.
Why do lifters use knee sleeves?
- Warmth through the session. Neoprene keeps the knee area warm between sets.
- A snug, supported feel on squats. Lifters who squat often like the firm, close fit of a 7mm sleeve.
- Comfort on long sessions. A thin compression sleeve can be worn for long training days, runs and court sports.
- Consistency. Wearing the same sleeve every session makes heavy days feel familiar.
Knee sleeves are training gear, not a replacement for good technique, a sensible program or advice from a health professional. If you have knee pain or a knee condition, ask a doctor or physical therapist before choosing any knee product.
3mm vs 5mm vs 7mm: which knee sleeve thickness do you need?
Knee sleeves usually come in three thicknesses. Thicker sleeves feel firmer and warmer but are harder to pull on; thinner sleeves are lighter and more flexible.
| Thickness | Feel | Typical use | Nordic Lifting option |
|---|---|---|---|
| Thin knit (similar to 3mm) | Light, breathable, flexible | Running, court sports, long training days | Knee Compression Sleeves (nylon, spandex and latex knit) |
| 5mm | Medium thickness, in between | Occasional lifting mixed with other sports | We do not make a 5mm knee sleeve. Our 5mm sleeve is for elbows: Elbow Sleeves, 5mm |
| 7mm | Thickest and firmest, takes some effort to pull on | Heavy squats, lunges, leg presses, regular leg days | 7mm Knee Sleeves (neoprene, reinforced stitching) |
5mm or 7mm? If you squat every week and want a firm, warm fit, choose 7mm. If you mostly run, play sports or train for long sessions and want something you barely notice, choose a thin compression sleeve. Since we only make 7mm in neoprene, our range is a choice between the firm 7mm sleeve and the light knit sleeve.
How to choose knee sleeves
- Your training. Heavy squats and leg days point to 7mm neoprene. Running, sports and all-day wear point to a thin knit sleeve.
- Thickness and stiffness. Thicker means firmer and warmer; thinner means more freedom to move.
- Material. Neoprene is thick and warm. Nylon and spandex knit is thin and breathable.
- Size and fit. The right size matters more than anything else. Measure first (see below) and use the brand's own chart.
- Comfort. A sleeve that pinches, itches or slides down will distract you in the middle of a set.
- Durability and care. Reinforced stitching and gentle washing help a pair last.
How to measure for knee sleeves
Every brand sizes its sleeves a little differently, and some measure at the center of the kneecap. For Nordic Lifting 7mm knee sleeves, the size chart uses your thigh measurement 4 inches above the kneecap.
- Use a soft tape measure. A flexible cloth or plastic tape wraps around the leg; a rigid tape or ruler will not.
- Measure on bare skin. Shorts are fine. Leggings or sweatpants add width.
- Find the spot. Measure 4 inches (about 10 cm) up from the top of your kneecap.
- Wrap the tape around the thigh. Keep it flat and snug, without pressing into the skin.
- Measure twice. If the two numbers differ, use the average.
- Match it to the chart. Use the size chart in the product photos. For a tighter, competition-style fit, go one size down.
For our knee compression sleeves, use the size chart in their product photos. The right size should feel snug and still let you bend the knee freely.
How should knee sleeves fit?
- Snug, not painful. You should feel even compression all the way around, with no pinching or numbness.
- Centered on the knee. Pull the sleeve up until the kneecap sits about in the middle. Our 7mm sleeves are about 26.5 to 27 cm tall in every size.
- Stays put. It should not slide down during squats or lunges.
- Full bend. You should still be able to reach full depth comfortably.
- 7mm takes effort to pull on. That is normal for thick neoprene, especially if you sized down.

How to care for knee sleeves

Frequently asked questions
What are knee sleeves?
Knee sleeves are pull-on sleeves, usually neoprene or knit nylon, that give the knee warmth and a snug, compressive fit while you train. They have no hinges or rigid parts.
Where do you measure for knee sleeves?
It depends on the brand. For Nordic Lifting 7mm knee sleeves, measure around your thigh 4 inches above the top of the kneecap and match it to the size chart in the product photos. Other brands may measure at the center of the kneecap, so check their chart.
Should knee sleeves be tight?
They should be snug enough to stay in place and give even compression, but never painful or numbing, and you should still be able to bend fully. 7mm sleeves take some effort to pull on, which is normal.
Should I size down in knee sleeves?
For our 7mm sleeves, follow the chart for a comfortable fit on long sessions. Go one size down only if you want a tighter, competition-style fit and do not mind a harder pull-on.
Are 5mm or 7mm knee sleeves better?
7mm sleeves are thicker, firmer and warmer, which suits lifters who squat often. 5mm sleeves are a middle option for occasional lifting. Nordic Lifting makes 7mm neoprene knee sleeves and thin knit compression sleeves, not a 5mm knee sleeve.
What is the difference between knee sleeves and knee compression sleeves?
Our 7mm knee sleeves are thick neoprene built for heavy squats. Our knee compression sleeves are thin, breathable knit built for movement and long wear.
How high should knee sleeves be?
Pull them up until the kneecap sits about in the middle of the sleeve. Our 7mm sleeves are about 26.5 to 27 cm tall, so they cover the knee with some room above and below.
Knee sleeves vs knee braces: what is the difference?
A knee sleeve is a flexible pull-on sleeve for warmth and compression. A knee brace has hinges, straps or stays that limit how the joint moves, and is usually chosen with a health professional.
