FAQs
What are 7mm and 5mm sleeves used for?
7mm sleeves are built for heavy squats, Olympic lifting, and strength-focused training where maximum compression and joint stability matter most.
5mm sleeves offer lighter compression with greater freedom of movement, better suited to CrossFit, functional fitness, and all-round training sessions where mobility matters alongside support.
What is CR grade neoprene?
CR (Chloroprene Rubber) is a premium grade of neoprene known for its durability, consistent compression, and resistance to breaking down under repeated heavy use. It's the same material standard used in competition-grade equipment, built to outlast standard gym sleeves.
Are they hard to get on?
They can feel snug at first, that's normal and part of what gives you compression. If you're struggling, fold the sleeve in on itself, pull it up past your calf to just below the kneecap, then unfold it up over your knee. This makes getting them on far easier.
How long do they take to break in?
Due to the density of the material, allow 1-2 sessions for your sleeves to mould to your knee shape. Some lifters find it takes a few sessions more, this is completely normal and they'll continue to feel better with wear.
Can I wear these all day, or just during training?
These are built for training sessions, not all-day wear. Remove them after your session to let the neoprene and your skin breathe.
Do I need to size up or down from my normal size?
Mammal Knee sleeves run differently to other brands sizing. ALWAYS check the Size Guide and measure BELOW your kneecap rather than guessing from your usual size.
Can these be used for running or everyday wear?
7mm sleeves are built for heavy lifting, not running or extended low-intensity wear. If you want something for everyday training or endurance work, the 5mm or Thermal sleeves are a better fit.
