The Fitbit Alta HR wristband is made of a flexible, durable elastomer material similar to that used in many sports watches. The tracker is made with surgical-grade stainless steel, and the buckle is made with aluminum.
@ian_shakil The Fitbit Alta HR is splash-proof. When you're showering, it's a great time to charge your device, so you're not missing exercise or sleep tracking.
