      I was in the Middle East, Europe, Japan, Los Angeles and New York all within 3 weeks and FlyKitt worked great. Really terrific app and experience. The packaged experience combined with glasses and application is really top notch. Highly recommended.

      Happy to report that on 6 hours of travel I landed in Vegas feeling great. Meditated, took a nap, and rocked the socks off of 1200 people. Then, I took another red eye to Costa Rica and am feeling healthy, strong, and present. Excited for these to go global.

    Travelers Love FlyKitt:

    As a competitive athlete, you have to show up “race ready”. Travel is one of the most challenging variables. Jet lag can literally cost you the race, and wipe away months of training. FLYKITT by@FountBiois a game-changer. I’ve had zero jet lag, and now won’t travel without it.

    Oh man, the new app for@AndrewHerrBio/@FountBio’s legendary Jet Lag cure kit is *fly AF.*DM me if you want early access to the new FlyKitt: the first commercially-available cure for Jet Lag, which until recently was available only to the military/select pro sports teams.

    It just works

    In an almost scientific study, I traveled once without FlyKit with disastrous results, no sleep, brain fog, and general suckiness for 3+ days. The next two trips to Europe with FlyKit have been amazing. Full night of sleep, alert and awake during the day, and most importantly perform at my best for work and play. I won’t make another trip without it.

    First deployment that I hit the ground running

    Been doing deployments for 26 years- that’s a lot of time to figure out traveling halfway around the world not only sucks, but I’ve never been 100% there until a few days into the cycle. That’s just been the way it’s been- for me and everyone else around me… This time- completely different- I slept through the entire evening the first day I got here-(18 hour difference between home and location) and then was up and set from that day going forward- I’ll never do another deployment or travel across time zones without this FlyKitt travel kit or the plan- it’s so easy to follow the guidelines for eating, sleeping, supplementation all through the app! Seriously the best travel hack I’ve ever found!


    The best for long flights and overcoming jet lag!
