Patents Aren't Just Paperwork — They're Proof
In the world of sports gadgets, anyone can sell you a gadget. A patent, though — that's different. A patent means the invention was novel enough, non-obvious enough, and backed by enough real-world evidence to earn a legal monopoly. GO²'s breathing technology holds that distinction, and it's the reason the numbers behind it are numbers you can trust.
Designed by Doctors, Built on Physiology
The GO² endurance device wasn't cooked up in a marketing meeting. It was designed by doctors who understood a simple, overlooked truth: your breathing is a performance bottleneck. Most training focuses on legs and lungs, but the muscles of your breathing apparatus fatigue just like any others — and when they do, oxygen delivery drops and your heart has to work harder to compensate.
GO²'s patented design targets that exact mechanism. By optimizing the way air flows through the device, it reduces the work your breathing muscles do — which means more oxygen where it counts, a lower heart rate at the same effort, and endurance gains you can measure.
The Numbers Behind the Patent
GO² is the only breathing device scientifically proven to:
- Increase endurance by 6% — measured in controlled testing, not anecdote
- Increase VO2 max by 4% — the gold-standard metric of aerobic capacity
- Increase oxygen intake while lowering heart rate — the rare combination that every endurance athlete chases
Those aren't round-number marketing claims. They're specific, replicable results — the kind of evidence a patent examiner and a scientist both look for.
Trusted Where Failure Isn't an Option
The technology isn't just validated in the lab. It's been relied on by athletes who can't afford for equipment to fail: World Mountain Running Champion Joseph Gray, pro high-altitude climber Don Bowie, 24x IRONMAN finisher Ricardo Urbina, and 3x IRONMAN champion Laurel Wassner. When your event is run at 14,000 feet or stretches past 12 hours, you don't gamble on gimmicks — you use what the patent protects.
What a Patent Protects You From
Here's what the patent really means for you as an athlete: every cheap copycat on the market is guessing. Imitations can copy the look, but they can't copy the validated mechanism without infringing — which means the device you're buying for $60 is the real, tested article, not a knockoff riding on someone else's research.
- WADA legal — compete anywhere with total confidence
- Made in USA — manufactured to exacting standards
- No expiration date — unlike foam shoes that die after ~150 miles, your GO² keeps working
Your Secret Weapon Is Patented
Six percent more endurance. Four percent more VO2 max. Lower heart rate. At $60, it's the cheapest legal performance edge you can own — and the patent guarantees there's nothing else like it.
