Pain under your kneecap? Keep playing. The Second Set strap worn just below the kneecap: airbag inside, stays put, one size.
It sits right on the spot that hurts: the pad rests on the patellar tendon, just below the kneecap, and takes the load off it.
An airbag for your tendon: the inside of the pad, with the air pocket that cushions every landing and springs back.
On in seconds: 1, the pad under the kneecap, notch up; 2, close it behind the leg; 3, play. One size, fits 30 to 45 cm (12 to 18 in).
Before and after: without the strap, knee pain; with Second Set, back in the game.
Second Set compared with a sleeve, a hinged brace and tape: airbag inside, targets the tendon, stays put, slim under shorts, on in seconds, reusable.

  • Slim 3 cm knit band that breathes and wicks sweat
  • Hook-and-loop closure with a brushed-metal slider: set it once
  • One size: the slider adjusts it to your leg, 30–45 cm (12–18 in) around
  • Three colours: Ink, Chalk and Blush
  • Sold as a Single, a Doubles Pack (2 straps) or a Club Pack (4 straps)Sold one by one, 2 for the price of 1, or 4 for less than the price of 2

A support strap, not a medical device: it helps you keep playing, it doesn't treat an injury.

Second Set is a support strap, not a medical device.

Is it right for me?

Made for you if one of these sounds familiar.

1
Sharp pain just under the kneecap

It bites when you lunge, jump or push off. That's your patellar tendon asking for help.

Most players start here
2
Your knee aches the morning after

Fine during the game, stiff on the stairs the next day. The pad takes load off the tendon while you play.

Feel it from the first session
3
Your sleeve or tape keeps slipping

Sleeves ride down, tape peels by the second set. The silicone pad grips the skin and stays put.

Set once, forget it
4
No pain yet, and you want to keep it that way

You play 3+ times a week and you're not 20 anymore. Players who protect the tendon early stay on court longer.

Prevention beats rehab

The airbag inside

It takes the shock, so your tendon doesn't.

The raised centre of the pad holds a sealed air pocket that sits right on your patellar tendon.

The strap

16/20

people showed less strain on the patellar tendon with a strap

That's the spot our pad sits on, just below the kneecap. It's also why physios often suggest a patellar strap for jumper's knee.

Lavagnino et al. · Sports Health · 2011

The strap supports your knee while you play; it doesn't treat an injury. Sharp pain or swelling? See a physical therapist first.

The experts

Coaches and physical therapists tried it first.

Alex Mercer Alex Mercer Coach · Certified Pickleball Coach & Pro Player · Florida Paddle Club, Miami
“The Florida heat makes standard knee braces completely unwearable. This strap is a breath of fresh air. It provides the exact patellar stability my players need for quick transitions without trapping sweat or sliding off mid-rally.”
Brad Miller Brad Miller Coach · Pickleball coach · Lone Star Pickleball Hub, Austin
“I used to wear bulky knee sleeves that trapped heat and slipped down during long drilling sessions. This strap delivers targeted compression exactly where it counts, locks in place, and stays completely cool.”
Dan Wright Dan Wright Coach · Head Pickleball Coach / PPR Certified · Austin Pickle Ranch, Austin
“Drilling everyday takes a massive toll on the knees. I've switched over over a dozen of my students to this strap because it doesn't restrict their lateral movement or speed when rushing the kitchen line.”
Emma Hale Emma Hale Physical therapist · Knee physio, DPT · Premier Physical Therapy, Scottsdale
“Secure it exactly two fingers below the kneecap before warm-ups. I recommend it to patients looking to offload patellar tendon stress during explosive kitchen line lunges without the bulk of a full brace.”

On before I lace up

I put it on before I lace up and forget about it until we're done. Three of the ladies in my group ordered one after asking about it.

Arrived in 6 days, fitted in 10 seconds

Tracked the whole way. One size really does fit: slide it on, close it, done. The 8-week program email landed the same day and the first session took me 15 minutes.

Two hours every morning

Our ladies' league plays two hours every morning. It's comfortable from the first game to the last and it doesn't leave marks on my leg.

Good on hot indoor courts

Our indoor club gets hot by the evening. The band breathes and the pad stays where it is, even when I'm soaked.

Binned my old sleeve

My neoprene sleeve turned into a sauna by the second set and kept bunching behind the knee. This only covers a strip under the kneecap, so the rest of my leg can breathe. The sleeve is going in the bin.

Before you order.

How does the money-back guarantee work?

60 days to play with it. Not better? One email and we refund you in full within 48 hours. Keep the strap.

Will I pay customs or import fees?

No. Prices include everything: no customs, no import duty, no surprise at the door, in the UK and in the US.

Will it fit my knee?

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. Doesn't fit you? The 60-day guarantee covers it.

Will it fix my knee pain?

It won't cure an injury, and we won't pretend it does. What it does: steady, targeted pressure on the patellar tendon, the spot physios often target with a strap for jumper's knee. In one study, 16 of 20 people showed less strain on that tendon with a strap in place. Sharp pain, swelling or a knee that gives way? See a physical therapist first.

Jumper's knee, Osgood or runner's knee: will it help?

The strap targets the patellar tendon, just below the kneecap. Players with pain in that exact spot feel it most. Pain around or behind the kneecap? It can still steady the knee, and the 60 days cover you if it isn't for you. It's a support strap, not a medical device.

Why do most players take two?

Padel is played in pairs. Two straps give you one per knee, or one for you and one for your partner. One size fits you both, so there's no size to ask.

When do I put it on?

Before your warm-up: two fingers below the kneecap, snug but comfortable. Take it off after the match and let it air dry.

Will it get in the way of my game?

No. It sits under your kneecap, stays slim under shorts, leggings or a skirt, and your knee bends freely.

Which colour should I pick?

Three colours, same strap, same price: Ink (black), Chalk (grey) and Blush (pink). Buying a Doubles or Club pack? Tap Mix colours and pick one per strap.

Can I wear it for other sports too?

Yes. It works for any sport that stops and starts: padel, pickleball, tennis, running or the gym.

How do I get the 8-week program?

It's free with every strap. The download link is in your order confirmation email, so you can start the same day.

Your knee. Your padel game back. 2 straps for the price of 1.
