Patent-pending flip support · For women who lift

Knee support, built into your leggings.

Flip the built-in sleeve up over your knees for multi-layer support on squats, lunges, or wherever you need it. Flip it down and they look like regular leggings again. Nothing extra to pack, pull on, or forget in the car.

One flip. Two modes.

The built-in sleeve is your knee support. Down, it looks like regular leggings. Up, it's support. It's always with you.

Wear it like your favourite leggings

Wear it like your favourite leggings

Warm-ups, upper-body days, the drive home. Sleek, full length, nothing bulky.

Five seconds between sets

Flip the sleeve up over each knee. No taking shoes off, no pulling anything on.

Layered support for heavy leg days

03 · Up

Layered support for heavy leg days

Multiple layers, cut at a specific angle, sit snug over the knee through squats, lunges and leg press.

The problem we got tired of

You started lifting to get stronger. Not to babysit knee sleeves.

Sleeves rolling down mid-set, pulled off and on between exercises, sweaty, left at home on leg day. Support is supposed to help your workout, not interrupt it.

Built for the long game

Lift heavier. Train for decades. Keep your knees in it.

Muscle mass peaks in our 30s and slowly declines after that, and women who strength train 2–3 days a week are linked to longer lives. Flipactiv is for the woman who's in it for strength, muscle and longevity, and wants support there when she needs it.

Patent-pending angle

A specific cut that holds over the knee as you bend.

Moisture-wicking, fast-dry

Breathable, odour-resistant performance fabric.

From one woman to another

Invented by a trainer who watched her clients fight their sleeves.

Aveeva was a competitive figure skater and high-level rugby player before becoming a personal trainer. She kept asking one question: why can't support be built into the activewear women already wear? Flipactiv is her answer.

Questions, answered

Is this a knee brace?

No. It's built-in, multi-layer compression support for training, not a medical brace. If you're managing an injury, check with your healthcare provider.
