Game changer for race day!

I used to hate poking holes in my expensive running shirts with safety pins. These magnetic clips are incredibly strong and held my bib perfectly steady throughout the entire marathon without slipping. Highly recommend!

Saves my favorite running tops

I was skeptical about the strength, but these exceeded expectations. No sagging, no flipping corners, and absolutely no holes in my shirt. I bought a second pair just to be safe for future races.

Great product, slight bulk

These work exactly as advertised and keep the bib flat against the chest. They are slightly thicker than traditional pins, but the trade-off of not ruining my gear is worth it. Very satisfied with the purchase.

Perfect for triathlons

Used these during my last triathlon transition. They were quick to attach and didn't snag on anything. The grip is solid, and my number stayed visible the whole time. A must-have for serious athletes.

No more torn shirts

Finally, a solution that doesn't damage technical fabric. The magnets are powerful enough to stay put even when I was sweating heavily. Easy to put on and take off in seconds before the race start.

Simple and effective

Why didn't I think of this sooner? Traditional pins are a pain and often bend or break. These magnetic buckles are durable, reusable, and make getting ready for a race so much less stressful.

5 FAQ

Q: Are these safe for people with pacemakers?

A: These clips contain strong magnets. Individuals with pacemakers or other implanted medical devices should consult their physician before use and generally maintain a safe distance from strong magnetic fields.

Q: Can I wash my shirt with the clips still attached?

A: We recommend removing the clips before washing your clothing to preserve the magnet's strength and prevent any potential damage to the washing machine drum or the clip itself.

Q: What if my bib has a timing chip attached to the back?

A: The clips work perfectly with standard timing chips. Just ensure you place the magnets on either side of the chip area or sandwich the chip gently between the layers without bending it sharply.

Q: Will these work on thick winter running jackets?

A: Yes, the neodymium magnets are strong enough to secure a race bib through most winter running jackets, provided the fabric thickness does not exceed 0.5 inches.

Q: Do they come in different colors?

A: Currently, we only offer the Matte Black finish to ensure a discreet look on all types of athletic wear, but we are considering more color options for future production runs.
