The sport loop band just arrived. It's comfortable and easy to put on and take off. With that said, I would not use this band for any active water sports (swimming, surfing, wakeboarding, water park, etc). The velcro on the watch separates far too easily - for active water activities. It takes less pressure to separate the velcro than using a single finger to turn on/off a wall light switch. I'm going to swap it with the band on my other Apple Watch.
