Born in Paris. Knit in Portugal. Worn everywhere.
Heavelyn was born in 2021 from a simple frustration: sportswear that sculpts at the expense of comfort, or delivers comfort at the expense of line. Three years later, we work with a single family-run mill in Guimarães to knit essentials that hold you the way a well-made garment should.
Read our storyYour questions, our answers.
How does the sculpting knit actually work?
Our 4th-generation knit uses variable-tension zones — denser at the waist and glutes, softer at the knees — knit as one piece, with no compressive seams. The result: a smooth silhouette without the pinch of traditional shapewear.
What is your return policy?
We offer 30 days of free returns from the delivery date. Items must be unworn, with tags attached. You can start a return from your account or via the tracking link in your email.
Where are Heavelyn products made?
Every piece is knit and finished in a family-run workshop in Guimarães, Northern Portugal — a mill our founders have worked with since 2021.
How do I care for my pieces?
Cold wash inside out with like colors, air dry. No tumble dryer, iron, or bleach. Cared for this way, our knit holds 500+ wears without losing compression.
