How to Choose Knee Sleeves
Thickness
7 mm sleeves give the most support for heavy squats; 5 mm offer more mobility for CrossFit; knit sleeves are light compression.
Fit
Measure around the knee; snug fits support more, but should not cut circulation.
Material
Neoprene adds warmth and rebound; knit nylon is breathable for daily wear.
Competition rules
Powerlifters should check federation-approved lists.
Pair or single
Some listings sell single sleeves; check before buying.
Use
Sleeves support and warm the joint; they don’t replace good technique or medical care.
