Welcome to the official Fitnus Knee Sleeve Help Center. Whether you are curious about sizing, wondering how our compression technology accelerates recovery, or ready to place your order, you will find everything you need below.
Product & Everyday Performance
What makes the Fitnus Knee Sleeve superior to traditional drugstore knee braces?
Most standard knee braces are either rigid and sweat-trapping or flimsy and ineffective. The Fitnus Knee Sleeve solves both problems with advanced 3D circular knit technology. It delivers medical-grade 360-degree gradient compression that supports ligaments and boosts microcirculation, all while maintaining a featherlight, ultra-breathable profile that fits smoothly beneath your daily clothing.
How does the Fitnus Knee Sleeve relieve joint pain and stiffness?
Our calibrated compression applies gentle, continuous pressure around the patella and joint capsule. This increases blood and oxygen flow, which helps flush out pooled inflammatory fluids, reduces swelling, and keeps the joint lubricated with soothing thermal retention. At the same time, the elastic weave absorbs shock and stabilizes your movements, taking direct strain off your cartilage and meniscus.
Can I wear the Fitnus Knee Sleeve while working out or playing sports?
Absolutely! The sleeve is engineered for high-movement performance. It provides dynamic lateral stabilization and impact absorption during weightlifting, running, basketball, hiking, cycling, tennis, and cross-training without restricting your natural range of motion.
Will the sleeve slip, slide, or roll down when I walk or bend?
No. We designed the Fitnus Knee Sleeve with a contoured ergonomic knit that mirrors the natural tapering of your calf, knee, and thigh. This anatomic design grips the contours of your leg to prevent roll-down, bunching, and shifting—even through heavy squats and long daily strolls.
Is it bulky? Can I wear it under my normal clothes?
The Fitnus Knee Sleeve is exceptionally slim. Its discreet micro-knit weave allows it to hide seamlessly beneath denim jeans, office slacks, athletic tights, or work uniforms so you can enjoy invisible all-day joint support wherever you go.
Sizing, Fit & Daily Wear
How do I choose the right size for my knee?
Our 3D high-stretch weave provides an adaptive fit that flexes to your unique leg shape. To find your ideal match, measure the circumference of your thigh roughly 4 inches (10 cm) above the center of your kneecap, then check our official size chart on the product page. If you are between two sizes, we suggest sizing down for firmer, athletic compression or sizing up for a gentler, relaxed daily wear fit.
Can the Fitnus Knee Sleeve be worn on either the left or right knee?
Yes. Each sleeve features an ambidextrous, universal design that provides an identical ergonomic fit and compression profile on either your left or right leg.
Can I wear the sleeve for the entire day?
Yes! The moisture-wicking microfibers allow your skin to breathe naturally, making the sleeve ideal for full workdays, travel, and extended outdoor activities. However, we advise taking it off before going to bed at night so your muscles and circulatory system can rest without compression.
Can I wear two sleeves at the same time?
Definitely. Many of our customers wear a pair to maintain balanced support, protect both knees evenly during intense physical tasks, and avoid overcompensating on an uninjured side.
Care, Cleaning & Durability
How should I wash and care for my Fitnus Knee Sleeve?
To protect the elasticity and lifespan of the compression fibers:
- Hand wash in cold or lukewarm water using a mild liquid detergent.
- Gently squeeze out excess water—do not wring or twist.
- Lay flat to air dry away from direct sunlight and artificial heat.
- Avoid bleach, fabric softeners, ironing, and machine tumble-drying.
Will the compression loosen or stretch out over time?
No. Our multi-directional nylon-spandex weave is built to withstand repeated washings and daily wear while maintaining its calibrated compression and spring-back recovery.
