Yes. Second Set is one size: the metal slider and the hook-and-loop set it to your leg, 30–45 cm (12–18 in) around, measured two fingers below the kneecap. Set it once and it stays set.

Because the slider does the sizing. No chart, no wrong guess, nothing to send back, and a Doubles Pack you can share without asking your partner's size. Doesn't fit you? The 60-day guarantee covers it.

Three colours, same strap, same fit, same price: Ink (black), Chalk (grey) and Blush (pink). Every strap in a pack comes in the colour you pick.

Two fingers below the kneecap, with the silicone pad centred on the soft spot between the kneecap and the shin bone.

Snug, not tight. It should hold when you move, with no pinching, tingling or numbness.

Second Set is a support strap, not a medical device, and it doesn't treat injuries. If your knee hurts, see a physio or a doctor.

Hand wash in cold water and let it air dry.

No. A wall, a chair and a low step are enough.
