It’s comfortable but after a few hours the skin around the libre becomes so itchy that I have to take the band off.
The armband makes me feel that my sensor is secure when doing exercises.
Libreband Armband for Freestyle Libre 1 & 2, Teal Heart. I wore it for the first time 7 Sept 23 at a Aqua aerobics class. I asked one of the life guards to tighten the armband for me. We had to be chest high in water so I needed to wear the armband. It worked, it did not fall off and when I took it off I could still see my readings. As it was away from my phone I had no signal anyway but I did eat extra food before class so not to go low whilst exercising.
Very nice don't really know how long it will last ,I will have to wait and see
