Did my first boot camp style workout with the lte watch and sport loop. I sweated heavily for a solid hour and the watch was extremely comfortable and forgot I had it on. I used the HIIT workout setting and ended the workout at 80% battery. It did take a full 3 hours for the band to completely dry. After an hour it was just damp and could hardly notice. I might get another sport loop to switch out rather than rubber. I like the feel and ability to adjust it so easily.
