Magic Dial Secrets
The Precision Compression Dial is your personal volume knob for comfort. Simply twist to tighten for extra support during long walks, or loosen it up when you are relaxing on the sofa. It is all about giving you the perfect squeeze whenever you need it.
Sizing Your Hug
Pick your size based on your weight! Small fits 110–130 lbs, Medium 131–165 lbs, Large 166–200 lbs, XL 201–240 lbs, and XXL is for our sturdy friends over 240 lbs. If you are right on the edge, we recommend sizing up for the coziest fit.
Laundry Day Fun
To keep your Peakflex sleeve bouncy and bright, we recommend a gentle hand wash with mild soap. Air dry it in the shade—no tumble dryers, please! This keeps the silicone grip sticky and the gel pad perfectly plump.
The Peakflex Promise
We ship your knee's new best friend within 24 hours. If you accidentally ordered a 'Right' when you needed a 'Left,' don't panic! Our friendly team will swap it out faster than you can say 'skipping.'
