The 3mm Double Ply is our everyday sleeve: comfortable compression and knee support without the bulk of thicker neoprene. Here is who it suits and how to size it.
What They Are
The 3mm Double Ply Knee Sleeves use two bonded layers of fabric for extra durability, with moderate compression in a lightweight 3mm build. They give stable knee support with a comfortable fit that will not restrict movement.
Who They Are For
- Functional fitness and CrossFit athletes who want light support
- HYROX competitors
- General gym training
- Runners who want light knee support
Who Should Look Elsewhere
- Squatting heavy? You will want more compression from the V3 5mm or V3 7mm.
- Mainly after warmth for long runs? Compare with the Thermal Endurance sleeves.
Read Knee Sleeves for HYROX and Running for how the two lighter sleeves compare.
How to Size Them
Lighter sleeves are measured differently from our heavy V3 range.
- Where to measure: around the middle of the kneecap, with your knee bent to about 30 degrees
- Sizes: XS/S, M/L and XL/XXL
- Between sizes? Size down. A snug fit stops the sleeve slipping.
Looking After Them
Hand wash cold and air dry away from direct heat.
