THE UPGRADE
One buckle, two straps. Switch your style in a click.
Free worldwide shipping · no minimum
The shortcut over the pole. The belt that goes with everything.
The farthest reaches of the extreme south · the road for those who always go further.
Not sure? Go Slim. It fits everything. Both straps share the same buckle. The two widths cannot be mixed — choose the same width for both.

One buckle. Two straps. Every style.
The Upgrade gives you one buckle and two interchangeable straps in different colors. Keep the same buckle and switch straps depending on the outfit, the mood, or the destination. The mechanism is the same as on board: slide, pull, done. Two routes, one belt.
The aircraft seatbelt.
Resized for your pants.
It started with one belt almost nobody notices. The one in front of you on every flight. We kept the design, kept the spirit, and adapted it to the place you actually wear a belt.
We just resized the webbing for trouser loops and switched the buckle for a lightweight aluminum one, made for daily wear.

Offerte à mon chef pour son départ en retraite
30 ans chez Air France, il a choisi la Transatlantic et la Runway — le premier vol qu'il avait piloté (CDG-JFK) et la piste sur laquelle il a atterri pour son dernier vol. Il a serré la boucle en salle de pot de départ et il a eu les larmes aux yeux. Merci.
Father's Day gift, he loved it
Dad's a retired Delta pilot. I got him navy and black straps with one buckle. He sent me a selfie at Sunday brunch wearing it. First time in 10 years he liked one of my presents.
Two belts, one buckle, genius
The modular system is the real upgrade (pun intended). I can do black on weekdays and red on weekends with the same hardware. Swap takes 15 seconds. Worth every euro.
Groen en grijs dekken bijna alles
Twee kleuren, twee stemmingen. De groene draag ik bij linnen overhemden en een jeans, de grijze onder het colbert. Dezelfde gesp houdt beide — en maakt het wisselen meer een ritueel dan gedoe. Slimste accessoire dat ik dit jaar heb gekocht.
Two colors. One buckle.
The buckle is shared between both straps. Switch in seconds, exactly like on board. The aluminum buckle is built to last through both.
Every combination is yours.
Every color in the collection is available for both straps. Choose any two. Every pairing says something. Make it count.
Adjusts exactly like on board.
Slide the strap through the buckle and pull to tighten. Fits any waist size up to 110 cm continuously.
Built to fit every trouser.
Two widths. Slim (38mm) fits all standard belt loops including dress trousers, chinos and slim jeans. Authentic (48mm) is the exact on-board format, for jeans and cargo pants. Both straps must be the same width — the buckle is shared.
Born in Paris. Built on one obsession.
Fly-Belts was founded in Paris in 2012. The obsession: take the most iconic piece of aviation design and make it genuinely wearable. Not as a novelty. Not as a gadget. As a real belt, built to last, worn every day. Wear the plane.
The perfect gift.
Two colors make it personal and thoughtful. Ships in a fabric pouch inspired by business class amenity kits — ready to give, no wrapping needed.
Free worldwide shipping on every order, with no minimum. Every order is tracked. France and Europe: 3 to 5 business days. International: 7 to 14 business days.
Returns and exchanges are accepted within 30 days of delivery, provided the belt is new, unworn and in its original packaging — the pouch delivered with your order. Return shipping costs are at the buyer's expense. Refund within 2 business days of receiving the return. Wrong width? Wrong models? Contact us and we sort it out.
Lifetime guarantee on the buckle
Buckle guaranteed for life. The same hardware as in commercial airliners, redesigned for your waist. If it ever fails, we replace it.
