"Leg day! No probs FKN tights own it! flexibility is awesome, stand out in the gym FKN oath!" - Helen D

Do you know why gym leggings are pants? Because they are pants.

Not everyone is wearing leggings just to grab coffee with the girls, FKN ladies actually lift in them and THEN go and have coffee.

The world famous STFO (Stand The F#CK Out) Leggings are true to size and feature a giant right leg FKN Gym Wear logo.

They feature a mild scrunch bum and a supportive FKN Gym Wear woven waistband. 

Sublimated polyester/spandex fabric means that the print is actually dyed into the fabric so it is guaranteed to never crack or peel, no matter how big your legs and booty get.

✔ Woven Logo Waistband

✔ Slick Appearance

✔ Attention Grabbing AF

Our model is 162cm tall and wearing a size small. She is also wearing our Strapped Gym Crop to complete the look.

- Lay your leggings flat to air dry. Try hanging them over several rungs of a clothes horse rather than the clothes line so that they don't stretch out of shape.
- For best results, wash in cold or warm water only and never use fabric softener on your activewear. Fabric softener can damage the technical properties of a sports fabric and remove it's abilities to be sweat-wicking, anti-bacterial, etc.
- If you get a bleach stain on your black leggings, use a Sharpie to dab the spot back to black.
- To avoid getting any fluff or pilling on your leggings, try washing them in a lingerie bag with your crop tops and sports bras.
- If your leggings are wrinkled, never iron them! Use a clothing steamer, or even a hair dryer can help get the creases out.
- Built from 80% Polyester & 20% Spandex.
- Proudly designed in Australia by bodybuilders.
