READY FOR THE REVOLUTION in performance gear?

It was nearly 200 years ago the sewing machine was invented, and since then, there has been no more robust, no more durable alternative to the construction of seams, until now.

Stealth has developed a revolutionary seam welding technology, that uses no stitching, no external heat and no glue. By using a patented sonic and high-frequency welding process Stealth seams eliminate the problems of existing performance clothing and outdoor gear. Stealth seams are 50% stronger*, more durable, up to 90% warmer*, 50% slimmer*. And can be used to weld lightweight fabrics for the first time in history.

In use across apparel, outdoor gear, and tents, Stealth’s welded seam technology provides endless possibilities in creating revolutionary performance products.

Stealth seams are set to change the world.

No stitching, No glue and No external heat. No compromise.

Are you ready for the revolution?

Performance wear and outdoor gear has a major problem. It’s stitched.

No Stitching

No Glue

No Excuses

WHY WE EXIST.

Current performance clothing and outdoor gear has a problem. It’s stitched

Performance fabrics have evolved rapidly over the last decade: Lighter, denser, advanced membrane and weatherproof options are offered with promises to enable us to go further, do more and be closer to the world’s extreme elements than ever before. But the technology for which to manufacture garments and outdoor gear in these new fabrics has failed to keep pace. Until now.

Current methods of stitching fabrics and glueing seams are flawed. On a traditional performance jacket, stitching weakens the seam points and creates holes for water and air to seep through. Then, adding glued tape over the stitching adds another weak link, the tape adhesives make seams prone to delamination, tape then weakens on the seams making them permeable once again. And on lightweight fabrics the heat used to apply the tape damages the fabric rendering the seams ineffective.

Stealth has developed a revolutionary seam welding technology, that uses no stitching, no external heat and no glue. By using a patented sonic and high-frequency welding process Stealth seams eliminate the problems of existing performance clothing and outdoor gear. Stealth seams are; 25% stronger. 25% more durable. And able to weld lightweight fabrics for the first time in history.

Finally, it is possible to create outdoor performance gear that isn’t constrained by the weaknesses of traditional stitching methods. Now, the world can be experienced close-up without the fear of your gear failing you. No doubts. No vulnerabilites. No weak links. This is the world of performance without compromise. Stronger. Lighter. Tougher. Stealth seams set you free.

‘Having trekked extensively in Nepal I needed a performance jacket that I could 100% trust in whatever the conditions. My Stealth jacket was super warm and waterproof whilst being super light and durable – I couldn’t ask for anything better.’

    ‘Stealth’s technology is ground-breaking, the absolute gold standard in performance gear manufacturing. Not only can you barely see the seams, but they’re stronger and more durable than anything that has been done before. My go-to manufacture when only the best will do.’
