Hat, One Size, White/Silver

When I first saw this hat, I really liked the design and the functionality, particularly with my Garmin 920XT's Ant+ fucntion.I purchased this hat in June of 2015 and the hat worked wonderfully until July, that's when connectivity with my Garmin 920XT became very spotty. .A month after I purchased the hat, I noticed that there was an issue of spotty connection with my Garmin. I contacted Lifebeam and was told that they were working on a fix. They were very quick to respond to all my emails and I was satisfied with their customer service.A year passed since that contact, and since I saw no movement from Lifebeam, I contacted them again. I was told that there was no fix coming for it and that there would be none forthcoming, since they were concentrating on their Vi headphones.Although I was upset at first, the good folks at LifeBeam helped me and ultimately resolved my issue satisfactorily.I can say that this hat does work with bluetooth and although connectivity with Ant+ is no longer going to be supported, the hat does the trick and the measurements are very accurate as compared with my chest strap. I will use this hat from now on via bluetooth and will look into buying the Vi.

ordered it in white and black, I got two black ones and didn't know until I opened the box after the return date so i was stuck with 2 like items and unable to return one.

I just received my new LifeBEAM hat and am pleased to report that it is very much to my liking. It's comfortable, which I was concerned about given that there is obviously technology in it and I was concerned that it may affect comfort. So far so good. Synching up to my Garmin devices and iPhone has been painless.

Small size, black head band inside

This is my first optical HRM. I don't like the wrist-based ones since I don't like wearing anything that tight on my arms, especially while running. I usually put up about 40 miles a week and I always wear a hat unless it's dark. The Life BEAM Hat was the perfect product for me to try and get away from the chest strap. It synced effortlessly with my Garmin Fenix 2, as well as the Strava and Endomondo apps on my phone. It doesn't have to be wet before wear, so it pics up your HR accurately faster than the chest strap did. The hat is super light, breathable, and comfortable, no complaints there. Actually, I have no complaints at all.My only recommendation to Life BEAM is to consider making a headband that I can easily wear under a buff or beanie for cold weather, as well as to be able to wear while I'm wearing a head torch in the dark hours.

Doesn't work

I used the hat to track my kids' heart rate during runs and it gave me a clear cut analysis of when they were over their personal limits , with it I re-did their sports plan.

was to flimsy.
